Description

Technical Field

[0001] This application relates to the field of image forming technology, specifically to a consumable, a consumable detection method, a control method, and an image forming system. Background Technology

[0002] With the advancement of science and technology, image forming devices such as copiers, fax machines, and multifunction printers are widely used in people's work and daily life.

[0003] As a typical image forming device, its imaging principle is as follows: the laser performs selective exposure on the photosensitive component that is uniformly charged by the charging device in the processing box according to the image information to form a corresponding electrostatic latent image. Then, the latent image on the photosensitive component is formed into a toner image by the developing device, and the toner image on the photosensitive component is transferred to the printing medium by the transfer device, thereby forming a visible toner image on the printing medium. In related technologies, the high-voltage power supply in an image forming apparatus is generally turned on when the main motor of the image forming apparatus rotates. Some imaging components (such as transfer rollers, developing rollers, charging rollers, etc.) are prone to abnormalities when subjected to high-voltage power supply for a long time, which can affect the image quality. For example, when the high-voltage transfer is turned on for a long time or is abnormal, it can cause abnormal charging of the surface of the photosensitive component (such as the photosensitive drum), resulting in defects in the image.

[0004] It should be noted that the information disclosed in the background section of this application is intended only to enhance the understanding of the general background of this application, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] This application provides a consumable, a consumable testing method, a control method, and an image forming system to help solve the problem in related technologies where imaging components in an image forming apparatus are prone to malfunctions due to prolonged high-voltage power supply, thus affecting image quality.

[0006] In a first aspect, embodiments of this application provide a consumable for detachable installation in an image forming apparatus, the consumable including a magnetic unit configured to: When a first control signal is received, the system switches to a first state. The first state allows the magnetic unit to engage with the high voltage switching unit in the image forming apparatus, thereby enabling the high voltage switching unit to turn on the high voltage power supply unit in the image forming apparatus. When a second control signal is received, the system switches to a second state. In this second state, the magnetic unit and the high-voltage switching unit disconnect their magnetic interaction, thereby causing the high-voltage switching unit to disconnect the high-voltage power supply unit.

[0007] In one possible implementation, the consumables further include: An information processing device is used to send the first control signal and / or the second control signal to the magnetic unit.

[0008] In one possible implementation, the consumable further includes a switching unit electrically connected to both the information processing device and the magnetic unit, and the switching unit is configured to: Upon receiving the first control signal, the system switches to the disconnected state, causing the magnetic unit to switch to the first state. Upon receiving the second control signal, the system switches to the on state, causing the magnetic unit to switch to the second state.

[0009] In one possible implementation, the magnetic unit is specifically configured to switch to a first state when it receives a first control signal sent by the image forming apparatus; And / or, The magnetic unit is specifically configured to switch to a second state when it receives a second control signal sent by the image forming apparatus.

[0010] In one possible implementation, the magnetic unit includes an electromagnet, and the magnetic unit is specifically configured as follows: When the first control signal is received, the electromagnet switches to the energized state. The energized state allows the electromagnet to form a magnetic interaction with the high-voltage switching unit, so that the high-voltage switching unit can conduct the high-voltage power supply unit. When the second control signal is received, the electromagnet switches to a de-energized state. The de-energized state causes the electromagnet to disconnect its magnetic interaction with the high-voltage switching unit, thereby causing the high-voltage switching unit to disconnect the high-voltage power supply unit.

[0011] In one possible implementation, the magnetic unit includes a first magnetic element, a blocking element, and a first driving element, wherein the magnetic unit is specifically configured as follows: When the first control signal is received, the first driving member drives the blocking member to move along the first preset path to the first position, so that the first magnetic member and the high voltage switching unit form a magnetic interaction, thereby enabling the high voltage switching unit to conduct the high voltage power supply unit. When the second control signal is received, the first driving member drives the blocking member to move along the first preset path to the second position, so that the first magnetic member disconnects the magnetic interaction with the high voltage switching unit in the image forming apparatus, thereby causing the high voltage switching unit to disconnect the high voltage power supply unit.

[0012] In one possible implementation, the first driving member is used to drive the blocking member to move along a first preset path, the first preset path having a first position and a second position, wherein: When the blocking component is located at the first position of the first preset path, the first magnetic component and the high voltage switching unit form a magnetic interaction, so that the high voltage switching unit can conduct the high voltage power supply unit. When the barrier is located at the second position of the first preset path, the barrier prevents the magnetic interaction between the first magnetic component and the high-voltage switching unit, causing the high-voltage switching unit to disconnect the high-voltage power supply.

[0013] In one possible implementation, a receiving space is formed within the consumable body, and the receiving space has an opening on the surface of the consumable body. The first magnetic component is housed within the receiving space. When the blocking component is located at a first position on the first preset path, the blocking component is misaligned with the opening. When the blocking component is located at a second position on the first preset path, the blocking component closes the opening.

[0014] In one possible implementation, the magnetic unit includes a second magnetic element and a second driving element, and the magnetic unit is specifically configured as follows: When the first control signal is received, the second driving member drives the second magnetic member to move along the second preset path to the third position, so that the second magnetic member forms a magnetic interaction with the high voltage switching unit in the image forming apparatus, thereby enabling the high voltage switching unit to conduct the high voltage power supply unit. When the second control signal is received, the second driving member drives the second magnetic member to move along the second preset path to the fourth position, so that the second magnetic member forms a magnetic interaction with the high voltage switching unit in the image forming apparatus, thereby enabling the high voltage switching unit to conduct the high voltage power supply unit.

[0015] In one possible implementation, the second driving member is used to drive the second magnetic member to move along a second preset path, the second preset path having a third position and a fourth position, wherein: When the second magnetic component is located at the third position of the second preset path, the second magnetic component and the high voltage switching unit form a magnetic interaction, causing the high voltage switching unit to disconnect the high voltage power supply unit. When the second magnetic component is located at the fourth position of the second preset path, the magnetic interaction between the second magnetic component and the high voltage switching unit is broken, causing the high voltage switching unit to disconnect the high voltage power supply.

[0016] Secondly, embodiments of this application provide a consumable detection method applied to an image forming apparatus, wherein the consumable described in any one of the first aspects is detachably installed in the image forming apparatus, and the method includes: The magnetic unit in the consumable is controlled to switch between the first state and the second state according to a specified switching rule, and the on / off state of the high voltage switching unit is detected. If the on / off state of the high-voltage switching unit matches the specified switching rule, then the consumable is determined to be normal. If the on / off state of the high-voltage switching unit does not match the specified switching rule, then the consumable is determined to be abnormal.

[0017] In one possible implementation, controlling the magnetic unit in the consumable to switch between the first state and the second state according to a specified switching rule includes: A state switching command is sent, which is used to control the magnetic unit to switch between the first state and the second state according to a specified switching rule.

[0018] In one possible implementation, controlling the magnetic unit in the consumable to switch between the first state and the second state according to a specified switching rule, and detecting the on / off state of the high-voltage switching unit, includes: When a preset signal is detected, the magnetic unit in the consumable is controlled to switch between the first state and the second state according to the specified switching rules, and the on / off state of the high voltage switching unit is detected. The preset signal includes at least one of a power-on signal, a recovery ready signal, and a sleep / wake-up signal.

[0019] In one possible implementation, before controlling the magnetic unit in the consumable to switch between the first state and the second state according to a specified switching rule, and before detecting the on / off state of the high-voltage switching unit, the method further includes: Detect whether the initial on / off state of the high-voltage switching unit meets expectations; If the initial on / off state of the high-voltage switching unit does not meet expectations, then the consumable is determined to be abnormal.

[0020] Thirdly, embodiments of this application provide a control method for an image forming apparatus, wherein a plurality of consumables as described in any one of the first aspects are detachably installed in the image forming apparatus, and the plurality of consumables correspond to different colors; the method includes: Based on the image forming operation mode, a target consumable is determined from a plurality of consumables, and the color of the target consumable is matched with the image forming operation mode; The magnetic unit of the target consumable is switched to a first state, so that the magnetic unit in the target consumable and the high voltage switching unit corresponding to the target consumable in the image forming apparatus form a magnetic interaction, thereby enabling the high voltage switching unit corresponding to the target consumable to conduct the high voltage power supply unit corresponding to the target consumable.

[0021] In one possible implementation, the method further includes: The magnetic units of the other consumables (excluding the target consumable) are switched to a second state, causing the magnetic units of the other consumables to disconnect their magnetic interaction with the high-voltage switching unit corresponding to the other consumables in the image forming apparatus. This, in turn, causes the high-voltage switching unit corresponding to the other consumables to disconnect the high-voltage power supply unit corresponding to the other consumables.

[0022] In one possible implementation, the image forming operation mode includes a monochrome image forming operation mode and a color image forming operation mode.

[0023] Fourthly, embodiments of this application provide an image forming system, including: The consumables of the image forming apparatus and any one of the first aspects, wherein the consumables are detachably mounted on the image forming apparatus.

[0024] Compared with related technologies, the embodiments of this application, by setting a switchable magnetic unit in the consumables, can selectively turn on and off the high-voltage power supply unit in the image forming apparatus, thereby avoiding the imaging components from being powered by high voltage for a long time when not necessary, reducing the impact of high voltage anomalies on the imaging components, and improving imaging stability and imaging quality.

Detailed Implementation

[0028] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0029] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0030] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0031] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0032] See Figure 1 This is a schematic diagram of the structure of an image forming system provided in an embodiment of this application. Figure 1As shown, the image forming system includes an image forming apparatus and consumables. The image forming apparatus is the part of the image forming system that performs the image forming operation, and the consumables are replaceable parts of the image forming system. For example, when the image forming apparatus is an inkjet printer, laser printer, 3D printer, label printer, or dot matrix printer, the corresponding consumables are ink cartridges, toner cartridges, drum units, toner cartridges, ribbon cartridges, etc.

[0033] One possible implementation is that the consumable has a separate structure, including a drum cartridge and a developing cartridge that are detachable from each other. The drum cartridge includes a photosensitive drum and a charging roller, while the developing cartridge includes a developer container, a developing roller, and a developer delivery element. Another possible implementation is that the consumable has an integrated structure, for example, including a developer container, a developing roller, a developer delivery element, a photosensitive drum, and a charging roller. Further, the consumable may also include only a housing and a developer container. It should be noted that the consumable may also be the aforementioned developing cartridge or drum cartridge. The aforementioned developer container is used to hold a developer such as toner, and the developer delivery element is a component such as a toner delivery roller or a toner delivery screw used for stirring and / or delivering toner. Of course, the aforementioned developing cartridge may also include only the aforementioned developer container, which is not limited here. Furthermore, the aforementioned developing cartridge may also include only the aforementioned developer container and developer delivery element, which is not limited here. In one possible implementation, the consumable may also include a toner cartridge and / or an imaging assembly. The toner cartridge is used to deliver toner to the imaging assembly when the toner in the imaging assembly is insufficient, so that the image forming apparatus can form an image based on the toner delivered by the imaging assembly. When the consumable is a toner cartridge, it may consist only of a housing and a developer container, or it may include a housing, a developer container, and a developer delivery element; this is not limited here. When the consumable is an imaging assembly, it may include a housing, a developer container, a developer delivery unit, a charging roller, a photosensitive drum, etc. A developer transfer channel is provided between the developer container and the imaging assembly; this is not limited here.

[0034] It should be noted that the consumables mentioned in the embodiments of this application can also be other easily damaged components, parts, or units (such as paper boxes) in the image forming apparatus that need to be replaced, which also belong to the technical solutions corresponding to the consumables protected in this application.

[0035] In related technologies, the high-voltage power supply in an image forming apparatus is generally turned on when the main motor of the image forming apparatus rotates. Some imaging components (such as transfer rollers, developing rollers, charging rollers, etc.) are prone to abnormalities when subjected to high-voltage power supply for a long time, which can affect the image quality. For example, when the high-voltage transfer is turned on for a long time or is abnormal, it can cause abnormal charging of the surface of the photosensitive component (such as the photosensitive drum), resulting in defects in the image.

[0036] To address the aforementioned issues, this application provides a consumable that, by incorporating a switchable magnetic unit, allows for the selective switching on and off of the high-voltage power supply unit in the image forming apparatus. This prevents the imaging component from being powered by high voltage for extended periods when unnecessary, reduces the impact of high-voltage anomalies on the imaging component, and improves imaging stability and quality. The specific implementation will be described in detail below.

[0037] See Figure 2 This is a schematic diagram of another image forming system provided in an embodiment of this application. Figure 2 As shown, the image forming system includes an image forming apparatus and consumables, with the consumables being detachably mounted on the image forming apparatus.

[0038] The image forming apparatus includes a high-voltage switching unit and a high-voltage power supply unit. The high-voltage switching unit can selectively turn the high-voltage power supply unit on or off. When the high-voltage switching unit turns the high-voltage power supply unit on, the high-voltage power supply unit can provide high-voltage power to components such as the transfer roller and charging roller, i.e., apply high voltage; when the high-voltage switching unit turns the high-voltage power supply unit off, the high-voltage power supply unit stops providing high-voltage power to components such as the transfer roller and charging roller, i.e., reduce high voltage.

[0039] The consumable includes a magnetic unit configured to: when receiving a first control signal, switch to a first state, the first state enabling the magnetic unit to magnetically engage with a high-voltage switching unit in the image forming apparatus, thereby enabling the high-voltage switching unit to conduct the high-voltage power supply unit in the image forming apparatus; and when receiving a second control signal, switch to a second state, the second state enabling the magnetic unit to disengage from the high-voltage switching unit, thereby enabling the high-voltage switching unit to disconnect the high-voltage power supply unit.

[0040] It should be noted that the "imaging component" in the embodiments of this application refers to an imaging component that requires high-voltage power supply, such as a transfer roller or a charging roller. For the sake of brevity, it will not be described in detail below.

[0041] This embodiment of the application incorporates a magnetic unit in the consumables that can switch between different states. By utilizing the magnetic interaction between this magnetic unit and the high-voltage switching unit in the image forming apparatus, selective switching of the high-voltage power supply unit is achieved. This prevents the high-voltage power supply from being passively activated by the main motor of the image forming apparatus, allowing it to be controlled according to actual operational needs. This effectively avoids prolonged application of high-voltage power to the imaging components during unnecessary operating phases, reducing the risk of performance degradation and malfunctions due to continuous high voltage, thereby improving the imaging stability and quality of the image forming apparatus.

[0042] In practical applications, the state switching of the magnetic unit can be achieved through different control methods. One method is that the consumable itself controls the magnetic unit, and the other method is that the image forming apparatus controls the magnetic unit.

[0043] By controlling the consumables, the high-voltage power supply can be controlled according to the actual imaging needs, provided that the consumables are correctly installed. This avoids turning on the high-voltage power supply when the consumables are not installed or not in the working position (high-voltage power supply is usually not needed when the consumables are not installed or not in the working position). By controlling the image forming device, the high-voltage power supply can be centrally managed in conjunction with the overall workflow and operating status of the machine, so as to achieve a more flexible control strategy.

[0044] The different control methods described above will be explained below with reference to specific implementation methods.

[0045] See Figure 3 This is a schematic diagram of another image forming system provided in an embodiment of this application. Figure 3 As shown, the consumable also includes an information processing device, which is used to send a first control signal and / or a second control signal to the magnetic unit to control the magnetic unit to switch between different states. In specific implementations, the information processing device can be a consumable chip disposed on the consumable or other functional units with information processing capabilities; this application embodiment does not impose specific limitations on this.

[0046] Understandably, when consumables are not installed in the image forming apparatus, or when consumables are installed but not in a working position, the information processing device is typically in a power-off or sleep state. In this state, the information processing device usually does not send a first control signal to the magnetic unit to keep the magnetic unit in a second state (a state where it does not generate magnetic interaction with the high-voltage switching unit), thereby keeping the high-voltage power supply unit in a closed state. In this way, the high-voltage power supply can be avoided when consumables are not installed or not in a working position.

[0047] When the consumables are installed in the image forming apparatus and in the working position, and a high-voltage power supply to the imaging component is indeed required, the information processing device sends a first control signal to the magnetic unit, causing the magnetic unit to switch to a first state (a state that generates magnetic interaction with the high-voltage switching unit), thereby enabling the high-voltage power supply unit to conduct and achieve high-voltage power supply. When the imaging operation is completed or high-voltage power supply is no longer needed, the information processing device sends a second control signal to the magnetic unit, causing the magnetic unit to switch to a second state (a state that does not generate magnetic interaction with the high-voltage switching unit), thereby disconnecting the high-voltage power supply.

[0048] In this embodiment, by controlling the magnetic unit by the consumable itself, the high-voltage power supply can be turned on only when the consumable is installed and in the working position, thus avoiding the high-voltage power supply being turned on when the consumable is not installed or not in the working position, thereby reducing the risk of the high-voltage power supply having an adverse effect on the imaging component.

[0049] See Figure 4 This is a schematic diagram of another image forming system provided in an embodiment of this application. Figure 4 As shown, the consumable also includes a switching unit, which is electrically connected to the information processing device and the magnetic unit respectively. The switching unit is configured to: switch to an off state when receiving a first control signal, causing the magnetic unit to switch to a first state; and switch to an on state when receiving a second control signal, causing the magnetic unit to switch to a second state.

[0050] In this embodiment, the operating state of the magnetic unit is indirectly controlled by a switching unit, which can further improve the reliability and safety of the control while ensuring the switching function of the magnetic unit. For example, it can avoid problems such as excessive load, electrical interference, or unstable control caused by the information processing device directly driving the magnetic unit, and is beneficial to reducing the power consumption and design complexity of the information processing device.

[0051] In one specific implementation, the magnetic unit can be an electromagnet, and the switching unit can be a controlled conducting device (e.g., a transistor, MOSFET, etc.). When the consumable is installed in the image forming apparatus and is in the working position, the image forming apparatus provides operating power to the electromagnet, and the consumable controls the on / off relationship between the electromagnet and the grounding circuit through the switching unit, thereby realizing the control of the magnetic state of the electromagnet.

[0052] For example, when the information processing device outputs the first control signal, the switching unit switches to the off state, that is, disconnects the connection between the electromagnet and the grounding circuit, causing the electromagnet to switch to the energized state, corresponding to the first state of the magnetic unit. When the information processing device outputs the second control signal, the switching unit switches to the on state, that is, connects the electromagnet to the grounding circuit, causing the electromagnet to switch to the de-energized state, corresponding to the second state of the magnetic unit. Normally, the information processing device can default to outputting the second control signal, that is, defaulting to setting the electromagnet to the de-energized state.

[0053] In this embodiment, the image forming apparatus provides power to the electromagnet, and the consumable controls the electromagnet's operating state through a switching unit. This ensures the stability of the electromagnet's power supply while confining the high-voltage switching control logic to the consumable side. This approach eliminates the need for a separate power supply module, thereby reducing the consumable's structural complexity and manufacturing cost, and improving its versatility.

[0054] To facilitate understanding, the technical solutions provided in the embodiments of this application will be described in detail below with reference to specific implementation methods.

[0055] See Figure 5 This is a schematic diagram of another image forming system provided in an embodiment of this application. Figure 5 As shown, the image forming apparatus includes a data board, and the consumables include a consumable substrate and an electromagnet. An information processing device is mounted on the consumable substrate. When the consumables are installed in the image forming apparatus and are in the working position, the first power output port on the data board is electrically connected to the power input port of the electromagnet to provide operating power (24V for the electromagnet); the second power output port on the data board is electrically connected to the power input port of the information processing device to provide operating power (3.3V for the electromagnet); the clock port and data port on the data board are electrically connected to the clock port and data port of the information processing device, respectively, forming a clock line SCL and a data line SDA between the data board and the information processing device. The data board and the information processing device can exchange information based on the clock line SCL and the data line SDA.

[0056] Furthermore, the consumables also include a transistor Q, a first resistor R1, and a second resistor R2. The I / O port of the information processing device is electrically connected to the base of the transistor Q through the first resistor R1, the emitter of the transistor Q is electrically connected to the electromagnet, and the collector of the transistor Q is electrically connected to the ground circuit (GND); the first end of the second resistor R2 is electrically connected to the base of the transistor Q, and the second end is electrically connected to the ground circuit.

[0057] When the I / O port of the information processing device outputs a low level (first control signal), transistor Q is turned off, thus disconnecting the electromagnet from the ground circuit and energizing the electromagnet. When the I / O port of the information processing device outputs a high level (second control signal), transistor Q is turned on, de-energizing the electromagnet. Normally, the I / O port of the information processing device outputs a high level by default, meaning the electromagnet is set to a de-energized state by default.

[0058] It should be added that, Figure 5 The circuit structure shown is merely an exemplary illustration of an embodiment of this application. It is understood that those skilled in the art can make adaptive adjustments according to actual needs, and all such adjustments, without altering the basic function, should fall within the protection scope of this application.

[0059] In another implementation, the state switching of the magnetic unit can be controlled by the image forming apparatus. In this implementation, the magnetic unit is configured to directly receive control signals from the image forming apparatus and switch between different states according to the control signals. Specifically, when a first control signal is received from the image forming apparatus, it switches to a first state; and / or, when a second control signal is received from the image forming apparatus, it switches to a second state.

[0060] For example, when the image forming apparatus enters the working stage that requires applying high voltage power to the corresponding imaging component, the image forming apparatus sends a first control signal to the magnetic unit, causing the magnetic unit to switch to a first state, thereby generating a magnetic interaction with the high voltage switching unit, causing the high voltage switching unit to conduct the high voltage power supply unit; when the image forming apparatus enters the non-imaging stage, standby stage, or stage that does not require applying high voltage power to the imaging component, the image forming apparatus sends a second control signal to the magnetic unit, causing the magnetic unit to switch to a second state, thereby disconnecting the magnetic interaction, causing the high voltage switching unit to disconnect the high voltage power supply unit.

[0061] By controlling the magnetic unit through the image forming apparatus, the switching on and off of the high-voltage power supply can be coordinated with the overall workflow of the image forming apparatus. For example, the image forming apparatus can centrally control the state of the magnetic unit based on the printing task status, imaging process stage, fault detection results, or system operating mode, thereby achieving more flexible and precise high-voltage power supply management.

[0062] Furthermore, directly controlling the magnetic unit through the image forming apparatus reduces the internal control structure of the consumables, simplifying their structure and reducing design complexity and manufacturing costs. This approach also facilitates unified management of multiple consumables at the system level. For example, in an image forming apparatus with multiple consumables, the state of the magnetic unit of the corresponding consumable can be selectively controlled according to the current imaging mode, preventing high-voltage power supply from being applied to imaging components corresponding to non-target consumables.

[0063] For ease of understanding, the technical solutions provided in the embodiments of this application will be described in detail below in conjunction with the specific structures of the image forming apparatus and consumables.

[0064] See Figure 6 , Figure 7A and Figure 7B In this embodiment of the application, the consumable 10 is detachably installed in the mounting part 20 of the image forming apparatus. The image forming apparatus has components such as a transfer roller and a separation assembly, and the consumable has imaging components such as a developing roller and a charging roller.

[0065] The mounting section 20 includes a high-voltage switching unit 21, which comprises a conductive block 211, a first contact section 22, and a second contact section 23. Wherein: The first contact portion 22 is a high-voltage contact, and the second contact portion 23 is electrically connected to one or more rollers in the imaging component. The second contact portion 23 may also be a metal contact portion of one or more rollers in the imaging component.

[0066] The high-voltage switching unit 21 has a first coordination state and a second coordination state. For example... Figure 7A As shown, in the first engagement state, the first contact portion 22 and the second contact portion 23 are electrically connected to the conductive block 211, respectively. The first contact portion 22 and the second contact portion 23 are connected by the conductive block 211, enabling the imaging component to achieve high-voltage power supply. For example... Figure 7B As shown, in the second engagement state, the first contact part 22 and the second contact part 23 are disconnected, the circuit between the first contact part 22 and the second contact part 23 is non-conductive, and the imaging component is not powered by high voltage.

[0067] See Figure 8 The consumable 10 includes a consumable body 11 and a magnetic unit 12 disposed on the consumable body 11. The magnetic unit 12 has a first state and a second state. After the consumable 10 is assembled into the mounting part 20, wherein: When the magnetic unit 12 receives the first control signal, it switches to the first state and applies a magnetic force to the outside. The magnetic unit 12 can form a magnetic action cooperation with the high voltage switching unit 21, so that the high voltage switching unit 21 is in the first cooperation state. At this time, the first contact part 22 and the second contact part 23 are electrically connected through the conductive block 211, that is, the high voltage power supply unit in the image forming apparatus is turned on.

[0068] When the magnetic unit 12 receives the first control signal, it switches to the second state. The magnetic unit 12 no longer applies magnetic force or applies a very small magnetic force. The magnetic unit 12 can disconnect the magnetic action cooperation with the high voltage switching unit 21, so that the high voltage switching unit 21 is in the second cooperation state. At this time, the first contact part 22 and the second contact part 23 disconnect the electrical connection, that is, disconnect the high voltage power supply unit in the image forming apparatus.

[0069] This embodiment of the application incorporates a magnetic unit 12 in the consumable 10 that can switch between different states. By utilizing the magnetic interaction between the magnetic unit 12 and the high-voltage switching unit 21 in the image forming apparatus, selective switching of the high-voltage power supply unit is achieved. This prevents the high-voltage power supply from being passively activated by the main motor of the image forming apparatus, allowing it to be controlled according to actual operational needs. This effectively avoids prolonged application of high-voltage power to the imaging components during unnecessary operating phases, reducing the risk of performance degradation and malfunctions due to continuous high voltage, thereby improving the imaging stability and quality of the image forming apparatus.

[0070] The embodiments of the present invention provide a magnetic unit 12 and a high voltage switching unit 21 with multiple implementations. Those skilled in the art can make various combinations based on the following implementations or modifications, which are not limited here.

[0071] [Magnetic unit 12 in the first embodiment] Reference Figure 8 As shown, this is a magnetic unit 12 according to the first embodiment of this application. The magnetic unit 12 includes an electromagnet 121. Specifically, the magnetic unit 12 is configured such that: when a first control signal is received, the electromagnet 121 switches to an energized state, which allows the electromagnet 121 to form a magnetic interaction with the high-voltage switching unit 21, thereby enabling the high-voltage switching unit 21 to conduct the high-voltage power supply unit; when a second control signal is received, the electromagnet 121 switches to a de-energized state, which allows the electromagnet 121 to disconnect from the high-voltage switching unit 21, thereby enabling the high-voltage switching unit 21 to disconnect the high-voltage power supply unit.

[0072] See Figure 6 and Figure 8 The consumable body 11 is provided with a consumable-side electrical connection part 15, and the consumable-side electrical connection part 15 is provided with a consumable-side electrical contact 151. The electromagnet 121 is electrically connected to the consumable-side electrical contact 151 through a conductive structure. The mounting part 20 is provided with a device-side power supply part 24, and the device-side power supply part 24 is provided with a device-side electrical contact 241, wherein: When the consumable 10 is not installed in the mounting part 20 or is not installed properly, the consumable side electrical contact 151 on the consumable side electrical connection part 15 is not in contact with the device side electrical contact 241 of the device side power supply part 24, the electromagnet 121 is not powered, the electromagnet 121 is not magnetic, the high voltage switching unit 21 in the mounting part 20 is not subjected to magnetic force, the high voltage switching unit 21 remains in the second engagement state, the circuit between the first contact part 22 and the second contact part 23 is not conductive, and the imaging component is not powered by high voltage.

[0073] After the consumable 10 is assembled in the mounting section 20, the consumable-side electrical contact 151 on the consumable-side electrical connection section 15 contacts the device-side electrical contact 241 of the device-side power supply section 24. The image forming apparatus can switch the electromagnet 121 between a energized state and a de-energized state by switching the power supply state of the device-side electrical contact 241, thereby achieving selective switching on and off of the high-voltage power supply unit.

[0074] Specifically, when the image forming apparatus control device side electrical contact 241 is powered, the consumable side electrical contact 151 can obtain power from the image forming apparatus (receiving the first control signal), thereby powering the electromagnet 121 and making the electromagnet 121 magnetic. The electromagnet 121 can apply a magnetic force to the high-voltage switching unit 21 in the mounting part 20, causing the high-voltage switching unit 21 to switch to the first engagement state. The first contact part 22 and the second contact part 23 are electrically connected to the conductive block 211, and the first contact part 22 and the second contact part 23 are connected by the conductive block 211, so that the imaging component can be powered by high voltage.

[0075] When the power supply to the image forming apparatus control device side electrical contact 241 is cut off, the consumable side electrical contact 151 cannot obtain power from the image forming apparatus (receives the second control signal), and therefore cannot supply power to the electromagnet 121, causing the electromagnet 121 to lose its magnetism. The electromagnet 121 cannot apply magnetic force to the high-voltage switching unit 21 within the mounting portion 20, causing the high-voltage switching unit 21 to switch to the second engagement state. The first contact portion 22 and the second contact portion 23 are respectively disconnected from the conductive block 211, the first contact portion 22 and the second contact portion 23 are disconnected, and the high-voltage power supply to the imaging component is cut off.

[0076] Furthermore, the image forming apparatus is also equipped with a voltage detection module and a control module. The voltage detection module is used to detect the voltage in the image forming apparatus. The control module is used to cut off the power supply to the electrical contact 241 on the control device side when it is detected that the image forming apparatus has not printed for a long time or the voltage is unstable. At this time, the electromagnet 121 is not powered and the electromagnet 121 has no magnetism, so the high voltage switching unit 21 switches from the first engagement state to the second engagement state. At this time, the electrical connection of the imaging component will change from the on state to the off state.

[0077] Please continue reading. Figure 8In one possible implementation, a receiving space 13 is provided inside the consumable body 11. The receiving space 13 forms an opening at the bottom of the consumable body 11. The electromagnet 121 is housed in this receiving space 13, thereby preventing the electromagnet 121 from being exposed outside the consumable body 11, which would affect the aesthetics and increase the volume of the consumable body 11. After the consumable 10 is assembled in the mounting part 20, the opening of the receiving space 13 corresponds to the position of the high voltage switching unit 21. The consumable side electrical connection part 15 is also provided at the bottom of the consumable body 11. Along the preset installation direction of the consumable 10, the receiving space 13 and the consumable side electrical connection part 15 are arranged in sequence.

[0078] Please continue reading. Figure 6 , Figure 7A and Figure 7B In one possible implementation, the installation part 20 is provided with a guide path 25 to guide the consumable 10 into the installation part 20 along a preset installation direction and limit the consumable 10. The consumable side electrical contact 151 of the consumable side electrical connection part 15 is provided on the guide path 25. When the consumable 10 moves along the guide path 25, the device side electrical contact 241 and the consumable side electrical contact 151 do not contact each other until the consumable 10 is installed in place. At this time, the consumable side electrical contact 151 presses against the device side electrical contact 241 to achieve electrical connection. The position of the electromagnet 121 is also opposite to the position of the high voltage switching unit 21 to realize the control of the high voltage switching unit 21.

[0079] [Magnetic unit 12 in the second embodiment] See Figure 9A , Figure 9B and Figure 10 This is a magnetic unit 12 according to a second embodiment of the present invention. The magnetic unit 12 includes a first magnetic element 122, a blocking element 123, and a first driving element 124. Specifically, the magnetic unit 12 is configured such that: when a first control signal is received, the first driving element 124 drives the blocking element 123 to move along a first preset path to a first position, causing the first magnetic element 122 to form a magnetic interaction with the high-voltage switching unit 21, thereby enabling the high-voltage switching unit 21 to conduct the high-voltage power supply unit; when a second control signal is received, the first driving element 124 drives the blocking element 123 to move along the first preset path to a second position, causing the first magnetic element 122 to disengage from the high-voltage switching unit 21 in the image forming apparatus, thereby enabling the high-voltage switching unit 21 to disconnect the high-voltage power supply unit.

[0080] Specifically, the first magnetic component 122 is a permanent magnet. A receiving space 13 is provided inside the consumable body 11. The receiving space 13 forms an opening on the outer surface of the consumable body 11. The first magnetic component 122 is housed in the receiving space 13. The magnetic force of the first magnetic component 122 is mainly applied to the outside through the opening. Preferably, after the consumable 10 is assembled in the mounting part 20, the opening of the receiving space 13 corresponds to the position of the high voltage switching unit 21.

[0081] The barrier 123 is disposed on the outer surface of the consumable body 11, and is located on the same side of the outer surface as the opening of the receiving space 13. The barrier 123 can move along a first preset path, which has a first position and a second position. When the barrier 123 is located at the first position of the first preset path, the magnetic unit 12 is in a first state; when the barrier 123 is located at the second position of the first preset path, the magnetic unit 12 is in a second state. The first driving member 124 is used to drive the barrier 123 to move along the first preset path, wherein: When the consumable 10 is not installed in the mounting part 20 or is not installed properly, the magnetic force of the first magnetic component 122 is not applied to the high voltage switching unit 21 in the mounting part 20, or the applied magnetic force is small. The high voltage switching unit 21 remains in the second engagement state, the circuit between the first contact part 22 and the second contact part 23 is not connected, and the imaging component is not powered by high voltage.

[0082] After the consumable 10 is assembled in the mounting part 20, the high voltage switching unit 21 can be switched between the first and second positions by controlling the blocking member 123 to move along the first preset path between the first and second positions, thereby achieving selective conduction and disconnection of the high voltage power supply unit.

[0083] Specifically, when the first control signal is received, the first driving member 124 drives the blocking member 123 to move along the first preset path to the first position. The blocking member 123 is misaligned at the opening of the accommodating space 13. The magnetic force of the first magnetic member 122 can be transmitted and applied to the high voltage switching unit 21. The first magnetic member 122 and the high voltage switching unit 21 form a magnetic interaction, so that the high voltage switching unit 21 is in the first interaction state. The first contact part 22 and the second contact part 23 are electrically connected to the conducting block 211 respectively. The first contact part 22 and the second contact part 23 achieve circuit conduction through the conducting block 211, so that the imaging component can achieve high voltage power supply.

[0084] When the second control signal is received, the first driving member 124 drives the blocking member 123 to move along the first preset path to the second position. The blocking member 123 closes the opening of the accommodating space 13. The magnetic force of the first magnetic member 122 cannot reach the high voltage switching unit 21 through the blocking member 123, or only a very small magnetic force reaches the high voltage switching unit 21, so that the high voltage switching unit 21 is in the second engagement state. The first contact part 22 and the second contact part 23 are disconnected from the conductive block 211 respectively. The first contact part 22 and the second contact part 23 are disconnected, and the high voltage power supply to the imaging component is canceled. Furthermore, the image forming apparatus is also equipped with a voltage detection module and a control module. The voltage detection module is used to detect the voltage within the image forming apparatus. The control module is used to control the first driving member 124 to drive the blocking member 123 to move to the second position of the first preset path when it is detected that the image forming apparatus has not printed for a long time or the voltage is unstable. The blocking member 123 closes the opening of the accommodating space 13, and the magnetic force of the first magnetic member 122 cannot reach the high voltage switching unit 21 through the blocking member 123, or only a very small magnetic force reaches the high voltage switching unit 21, so that the high voltage switching unit 21 switches from the first engagement state to the second engagement state. At this time, the electrical connection of the imaging component will change from the conducting state to the disconnected state.

[0085] In one feasible embodiment, refer to Figure 10 As shown, the first driving component 124 includes a driving motor 1241, a driving gear 1242, and a driving rack 1243. The driving motor 1241 and the driving gear 1242 are both housed in the receiving space 13 to avoid affecting the aesthetics of the consumable 10 and increasing the volume of the consumable body 11. The driving rack 1243 is disposed on the barrier 123 and extends along a first preset path direction. The extension direction of the first preset path is parallel to the installation direction of the consumable 10. The output shaft of the driving motor 1241 is connected to the driving gear 1242, and the driving gear 1242 meshes with the driving rack 1243.

[0086] When it is necessary to move the barrier 123 from the second position of the first preset path to the first position of the first preset path, the drive motor 1241 drives the drive gear 1242 to rotate clockwise. Through the power transmission of the drive rack 1243, the barrier 123 can move linearly. When it is necessary to move the barrier 123 from the first position of the first preset path to the second position, the drive motor 1241 drives the drive gear 1242 to rotate counterclockwise. Through the power transmission of the drive rack 1243, the barrier 123 can move linearly in the opposite direction.

[0087] Those skilled in the art will know that the first driving component 124 can also be a driving cylinder. The piston rod end of the driving cylinder is connected to the blocking component 123. The piston rod of the driving cylinder extends and retracts, causing the blocking component 123 to move back and forth along the first preset path. The extension direction of the first preset path can also be set as a curved movement path according to actual needs, and is not limited here.

[0088] [Magnetic unit 12 in the third embodiment] Reference Figure 11A as well as Figure 11B The magnetic unit 12 shown is a third embodiment of the magnetic unit 12 provided by the present invention. The magnetic unit 12 includes a second magnetic element 125 and a second driving element (not shown). The magnetic unit 12 is specifically configured such that: when a first control signal is received, the second driving element drives the second magnetic element 125 to move along a second preset path to a third position, so that the second magnetic element 125 forms a magnetic interaction with the high voltage switching unit 21 in the image forming apparatus, thereby causing the high voltage switching unit 21 to conduct the high voltage power supply unit; when a second control signal is received, the second driving element drives the second magnetic element 125 to move along the second preset path to a fourth position, so that the second magnetic element 125 forms a magnetic interaction with the high voltage switching unit 21 in the image forming apparatus, thereby causing the high voltage switching unit 21 to conduct the high voltage power supply unit.

[0089] Specifically, the second magnetic component 125 is a permanent magnet, and it can be carried on a carrier 126. The carrier 126 is disposed on the outer surface of the consumable body 11. The second driving component is connected to the carrier 126, driving the carrier 126 to carry the second magnetic component 125 and move it along a second preset path. The second preset path has a third position and a fourth position, wherein: When the consumable 10 is not installed in the mounting part 20 or is not properly installed, the magnetic force of the second magnetic component 125 is not applied to the high voltage switching unit 21 in the mounting part 20, or the applied magnetic force is small. The high voltage switching unit 21 remains in the second engagement state, the circuit between the first contact part 22 and the second contact part 23 is not connected, and the imaging component is not powered by high voltage.

[0090] After the consumable 10 is assembled in the mounting part 20, the second magnetic component 125 can be controlled to move between the third and fourth positions along the second preset path to switch the high voltage switching unit 21 between the first and second cooperation states, thereby achieving selective conduction and disconnection of the high voltage power supply unit.

[0091] Specifically, when the first control signal is received, the second driving member drives the second magnetic member 125 to move along the second preset path to the third position. The magnetic force of the second magnetic member 125 can be transmitted and applied to the high voltage switching unit 21. The second magnetic member 125 and the high voltage switching unit 21 form a magnetic interaction, so that the high voltage switching unit 21 is in the first interaction state. The first contact part 22 and the second contact part 23 are electrically connected to the high voltage switching unit 21 respectively. The first contact part 22 and the second contact part 23 realize circuit conduction through the high voltage switching unit 21, and the imaging component can realize high voltage power supply.

[0092] When the second control signal is received, the second driving member drives the second magnetic member 125 to move along the second preset path to the fourth position. The second magnetic member 125 moves away from the high voltage switching unit 21. The magnetic force of the second magnetic member 125 cannot reach the high voltage switching unit 21, or only a very small magnetic force reaches the high voltage switching unit 21, so that the high voltage switching unit 21 is in the second engagement state. The first contact part 22 and the second contact part 23 are disconnected from the conductive block 211 respectively. The first contact part 22 and the second contact part 23 are disconnected, and the high voltage power supply to the imaging component is canceled.

[0093] Furthermore, the image forming apparatus also includes a voltage detection module and a control module. The voltage detection module is used to detect the voltage within the image forming apparatus. The control module is used to control the second driving member to move the second magnetic member 125 to the fourth position of the second preset path when it is detected that the image forming apparatus has not printed for a long time or the voltage is unstable. The second magnetic member 125 is away from the high voltage switching unit 21, and the magnetic force of the second magnetic member 125 cannot reach the high voltage switching unit 21, or only a very small magnetic force reaches the high voltage switching unit 21, so that the high voltage switching unit 21 switches from the first engagement state to the second engagement state. At this time, the electrical connection of the imaging component will change from the conducting state to the disconnected state.

[0094] The structure of the second driving component can refer to the structure of the first driving component 124 in the second embodiment, and will not be described in detail here.

[0095] [Magnetic unit 12 in the fourth embodiment] See Figure 12 and Figure 13This is the fourth embodiment of the magnetic unit 12 provided in this application. The structure of the magnetic unit 12 can refer to the structure of the magnetic unit 12 in the three embodiments described above, and will not be repeated here. The difference between the magnetic unit 12 and the magnetic unit 12 in the three embodiments described above is that the magnetic unit 12 obtains power in a different way. Specifically, the consumable body 11 has a consumable-side power supply unit 14, which can be a consumable chip. The relevant components in the magnetic unit 12 (e.g., electromagnet 121) are electrically connected to the consumable chip through the conductive member 16. The mounting part 20 is provided with a power supply spring. After the consumable 10 is installed in the mounting part 20, the consumable-side power supply unit 14 abuts against the power supply spring in the mounting part 20. The consumable-side power supply unit 14 obtains power from the image forming apparatus and then supplies power to the relevant components in the magnetic unit 12 (e.g., electromagnet 121).

[0096] Similarly, the image forming apparatus is equipped with a voltage detection module and a control module. When it is detected that the image forming apparatus has not printed for a long time or the voltage is unstable, the control module of the image forming apparatus controls the consumable chip to stop power supply or reverse power supply.

[0097] This configuration allows for controllable switching of the magnetic unit 12 between the first and second states.

[0098] It should be noted that, in addition to powering the magnetic unit 12 through the image forming apparatus or consumables, other power supply methods may exist. For example, the magnetic unit 12 may be powered by a separate power supply provided on the image forming apparatus or consumables, or by connecting to an external power supply (a power supply other than the image forming apparatus and consumables), or by the external power supply powering the magnetic unit 12 through wireless power supply technology, etc. The embodiments of this application do not impose specific limitations on these methods.

[0099] [High-voltage switching unit 21 in the first embodiment] See Figure 6 , Figure 7A and Figure 7B This application provides a first embodiment of a high-voltage switching unit 21. The high-voltage switching unit 21 includes a conductive block 211, a first contact portion 22, and a second contact portion 23. The first contact portion 22 and the second contact portion 23 are located on opposite sides of the conductive block 211 in the horizontal direction. The conductive block 211 contains a magnetic material. Alternatively, the entire conductive block 211 can be made of magnetic material, or at least a portion of the conductive block 211 can be made of a magnetically attractable metal material. In short, as long as the conductive block 211 can be magnetically attracted, the specific structure is not limited.

[0100] The conductive block 211 can move along a third preset path, which is a path extending along the direction of gravity. The third preset path has a first end and a second end, with the first end of the third preset path located above the second end of the third preset path. When the magnetic unit 12 is in the first state, the high voltage switching unit 21 is subjected to the magnetic force emitted by the magnetic unit 12, and the conducting block 211 rises to the first end of the third preset path. At this time, the first contact part 22 and the second contact part 23 are respectively connected to the conducting block 211. The first contact part 22 and the second contact part 23 realize circuit conduction through the high voltage switching unit 21, and the imaging component can realize high voltage power supply.

[0101] When the magnetic unit 12 is in the second state, the high voltage switching unit 21 is not subjected to the magnetic force emitted by the magnetic unit 12, or is subjected to a very small magnetic force. Due to gravity, the conductive block 211 falls to the second end of the third preset path, and the first contact part 22 and the second contact part 23 disconnect from the conductive block 211. At this time, the electrical connection of the imaging component will change from the conducting state to the disconnected state.

[0102] Preferably, at least one of the first contact portion 22 and the second contact portion 23 is an elastic structure. When the conductive block 211 is pulled upward to be inserted between the first contact portion 22 and the second contact portion 23, it is subjected to elastic compression from the first contact portion 22 and / or the second contact portion 23 to ensure the stability of the conductivity between the first contact portion 22 and the second contact portion 23.

[0103] In another embodiment, when the conductive block 211 is attracted upward, it is not inserted between the first contact portion 22 and the second contact portion 23, but is pressed against the side of the first contact portion 22 and the second contact portion 23, which can also achieve the conductivity stability of the first contact portion 22 and the second contact portion 23, and is not limited here.

[0104] [High-voltage switching unit 21 in the second embodiment] See Figure 14 , Figure 15A and Figure 15B This is the high-voltage switching unit 21 provided in the second embodiment of this application. The high-voltage switching unit 21 adopts a reed switch structure. A reed switch is a simple and reliable magnetic switch structure with stable structure and low cost. The reed switch includes a glass tube 212, a first magnetic reed 214 and a second magnetic reed 215. A sealed receiving cavity 213 is formed inside the glass tube 212 and is filled with inert gas. The first end of the first magnetic reed 214 is electrically connected to the first contact portion 22, and the second end of the first magnetic reed 214 extends into the receiving cavity 213. The first end of the second magnetic reed 215 is electrically connected to the second contact portion 23, and the second end of the second magnetic reed 215 extends into the receiving cavity 213.

[0105] In a specific implementation, the first contact portion 22 can be a partial area of ​​the first end of the first magnetic reed 214, that is, the first contact portion 22 is a part of the first end of the first magnetic reed 214; the second contact portion 23 can be a partial area of ​​the first end of the second magnetic reed 215, that is, the second contact portion 23 is a part of the first end of the second magnetic reed 215. Of course, the first contact portion 22 and the first end of the first magnetic reed 214 can also be two independent components, which are electrically connected by welding or other connection methods during installation; the second contact portion 23 and the first end of the second magnetic reed 215 can also be two independent components, which are electrically connected by welding or other connection methods during installation.

[0106] When the magnetic unit 12 is in the first state, the high voltage switching unit 21 is subjected to the magnetic force emitted by the magnetic unit 12, and the second end of the first magnetic reed 214 and the second end of the second magnetic reed 215 will attract each other together, thereby enabling the first contact part 22 and the second contact part 23 to achieve circuit conduction, and the imaging component can achieve high voltage power supply.

[0107] When the magnetic unit 12 is in the second state, the high voltage switching unit 21 is not subjected to the magnetic force emitted by the magnetic unit 12, or is subjected to a very small magnetic force. The second end of the first magnetic reed 214 and the second end of the second magnetic reed 215 are in the disconnected state. At this time, the electrical connection of the imaging component will change from the conducting state to the disconnected state.

[0108] Corresponding to the above embodiments, this application also provides a method for testing consumables.

[0109] See Figure 16 This is a schematic flowchart illustrating a consumable testing method provided in an embodiment of this application. This method can be applied to the image forming apparatus described above, such as... Figure 16 As shown, it mainly includes the following steps.

[0110] Step S1601: Control the magnetic unit in the consumable to switch between the first state and the second state according to the specified switching rules, and detect the on / off state of the high voltage switching unit.

[0111] In this step, the image forming apparatus can control the magnetic unit in the consumable according to a preset detection process, so that the magnetic unit switches between a first state and a second state according to a specified switching rule.

[0112] During the state switching of the magnetic unit, the image forming apparatus can simultaneously detect the on / off state of the high-voltage switching unit. The on / off state of the high-voltage switching unit can be obtained by detecting the output state of the high-voltage power supply unit, voltage changes, or other equivalent methods; this embodiment of the application does not specifically limit the detection.

[0113] In one feasible approach, a switching rule is specified to instruct the magnetic unit to switch to either a first state or a second state (single switching). After the magnetic unit completes the switching, the image forming apparatus detects the on / off state of the high-voltage switching unit at the corresponding moment. In this approach, the target state of the magnetic unit is clearly defined, the detection process is simple, and the detection efficiency is high.

[0114] In another possible implementation, a switching rule is specified to instruct the magnetic unit to switch multiple times between a first state and a second state (multiple switching), for example, switching states according to a preset number of times, a preset order, or a preset time interval. During the multiple switching of the magnetic unit, the image forming apparatus repeatedly detects the on / off state of the high-voltage switching unit and records the corresponding detection results. In this way, the on / off response of the high-voltage switching unit within multiple state switching cycles can be obtained.

[0115] In subsequent steps, by comparing the on / off status of the high-voltage switching unit with the specified switching rules, a basis can be provided for determining the status of consumables.

[0116] Step S1602: If the on / off state of the high-voltage switching unit matches the specified switching rule, then the consumables are determined to be normal.

[0117] In this step, the image forming apparatus compares the detected on / off state of the high-voltage switching unit with the specified switching rules.

[0118] In the above-mentioned single-switching implementation method, when the specified switching rule indicates switching to the first state, the high-voltage switching unit can be turned on as expected, or when the specified switching rule indicates switching to the second state, the high-voltage switching unit can be turned off as expected. Then it is considered that the on / off state of the high-voltage switching unit matches the specified switching rule, thereby determining that the consumable is in a normal state.

[0119] In the aforementioned multiple switching implementation method, the image forming apparatus can statistically analyze the on / off state of the high-voltage switching unit based on the multiple state switching of the magnetic unit. For example, if the high-voltage switching unit can change accordingly according to the specified switching rule during multiple switching processes, or if the number of matching reaches a preset threshold, then the on / off state of the high-voltage switching unit is considered to match the specified switching rule, thereby determining that the consumable is normal.

[0120] By using multiple switching and statistical judgment methods, the impact of occasional interference or transient anomalies on the detection results can be effectively reduced, thereby improving the accuracy of the detection results.

[0121] Step S1603: If the on / off state of the high-voltage switching unit does not match the specified switching rule, then the consumables are determined to be abnormal.

[0122] In this step, if the on / off state of the high-voltage switching unit fails to change according to the specified switching rules, the consumable is determined to be abnormal.

[0123] For example, in the single-switching implementation, if the specified switching rule specifies switching to the first state but the high-voltage switching unit is not conducting, or the specified switching rule specifies switching to the second state but the high-voltage switching unit remains conducting, then the consumable is considered to be abnormal.

[0124] In the implementation of multiple switching, if the high-voltage switching unit encounters switching response errors, insufficient response counts, or inconsistencies between the switching status and the specified switching rule during multiple state switching processes, it is considered that the switching status of the high-voltage switching unit does not match the specified switching rule, thus determining that the consumables are abnormal.

[0125] Once a consumable malfunction is detected, the image forming apparatus may stop the imaging operation, disable the high-voltage power supply, prompt the user to replace the consumable, or execute other malfunction handling procedures.

[0126] In this embodiment, the correspondence between switching rules and the on / off state of the high-voltage switching unit can be specified to detect consumables. This method can reliably detect consumables without increasing the complexity of the hardware structure, thereby improving the safety, stability, and imaging quality of the image forming apparatus.

[0127] In one possible implementation, the magnetic unit in the consumable is controlled to switch between a first state and a second state according to a specified switching rule. Specifically, this includes sending a state switching command, which is used to control the magnetic unit to switch between the first state and the second state according to the specified switching rule.

[0128] In practical applications, the state switching of the magnetic unit can be achieved either by the image forming apparatus sending a state switching command to the consumable, allowing the consumable to control the magnetic unit; or by the image forming apparatus directly sending a state switching command to the magnetic unit, thus achieving direct control of the magnetic unit's state. The following sections will explain these two implementation methods.

[0129] In one feasible approach, the image forming apparatus sends a state switching command to the consumable, which then controls the magnetic unit to switch between a first state and a second state based on the received command. Specifically, during the consumable inspection process, the image forming apparatus generates a state switching command based on a preset inspection strategy and sends it to the consumable. Upon receiving the state switching command, the information processing unit in the consumable controls the magnetic unit to complete the corresponding state switching based on the command content, thereby causing the high-voltage switching unit to produce a corresponding on or off change.

[0130] In another feasible approach, the image forming apparatus can directly send state switching commands to the magnetic unit without going through the consumable control unit, thereby controlling the magnetic unit to switch between a first state and a second state. For example, the image forming apparatus can directly change the operating state of the magnetic unit by providing a drive signal or control signal to the magnetic unit, causing a change in the magnetic interaction between the magnetic unit and the high-voltage switching unit, thereby enabling the high-voltage switching unit to be turned on or off.

[0131] In one possible implementation, the magnetic unit in the control consumable switches between a first state and a second state according to a specified switching rule, and detects the on / off state of the high-voltage switching unit. Specifically, when a preset signal is detected, the magnetic unit in the control consumable switches between a first state and a second state according to a specified switching rule, and detects the on / off state of the high-voltage switching unit; wherein the preset signal includes at least one of a power-on signal, a recovery ready signal, and a sleep / wake-up signal.

[0132] In this embodiment, by triggering the consumable detection process after detecting a preset signal, consumable detection can be combined with the critical state of the image forming apparatus, allowing consumable detection to be completed even when the device is first powered on, ready to resume operation, or awakened from sleep mode. This method can detect consumable anomalies before formal imaging, preventing abnormal consumables from participating in the imaging process, thereby improving the reliability of the image forming apparatus and the stability of image quality.

[0133] See Figure 17 This is a schematic flowchart of another consumable testing method provided in an embodiment of this application. This method... Figure 16 Based on the illustrated embodiment, the following steps are also included.

[0134] Step S1701: Check whether the initial on / off state of the high-voltage switching unit meets expectations.

[0135] In practical applications, the high-voltage switching unit usually has a preset default state. For example, when the consumables are not involved in imaging or when the image forming device is in standby or power-on initialization phases, the high-voltage switching unit remains in the off state.

[0136] In this step, when the image forming apparatus performs the consumable detection process, it first obtains the current on / off state (i.e., the initial on / off state) of the high-voltage on / off unit, and compares the initial on / off state with the preset default state to determine whether the initial on / off state of the high-voltage on / off unit meets expectations when no state switching control is performed.

[0137] Step S1702: If the initial switching state of the high-voltage switching unit does not meet expectations, then the consumables are determined to be abnormal.

[0138] For example, if the default state of the high-voltage switching unit is set to the off state, and the initial switching state of the high-voltage switching unit is detected to be the on state without sending the first control signal to the magnetic unit, then the consumable is determined to be abnormal.

[0139] In this embodiment, the initial on / off state of the high-voltage switching unit can be detected before the magnetic unit state switching is performed, thereby identifying consumables with obvious abnormalities in advance. On the one hand, this reduces unnecessary state switching operations and improves detection efficiency; on the other hand, it avoids continuing to perform subsequent detections when the initial state is abnormal, reducing the risk of misjudgment.

[0140] In the above embodiments, the focus was mainly on the high-voltage power supply control and consumable detection methods between a single consumable and the image forming apparatus. Based on the same technical concept, the embodiments of this application further consider application scenarios where multiple consumables are installed simultaneously in the image forming apparatus.

[0141] In practical applications, image forming apparatuses often have multiple consumables of different colors or functions installed simultaneously, such as imaging components corresponding to different color channels. In this case, not all consumables need to participate in every imaging stage. If high-voltage power is applied to multiple consumables at the same time, it is easy for the imaging components corresponding to some consumables to be subjected to high voltage for extended periods during unnecessary operating stages, thereby increasing the risk of imaging abnormalities or component degradation.

[0142] Based on this, this application proposes a control scheme for multiple consumables. By forming an operation mode based on an image, the high-voltage power supply unit corresponding to the target consumable is selectively turned on, while the high-voltage power supply unit corresponding to non-target consumables is kept off, thereby achieving refined high-voltage power supply control for multiple consumables. The following will describe this multi-consumable control scheme in detail with reference to specific embodiments.

[0143] See Figure 18 This is a schematic flowchart illustrating a control method for an image forming apparatus according to an embodiment of this application. The method can be applied to the image forming apparatus described above, which has multiple consumables detachably mounted therein, each consumable corresponding to a different color. Figure 18 As shown, it mainly includes the following steps.

[0144] Step S1801: Based on the image forming operation mode, determine the target consumable among multiple consumables, and the color of the target consumable matches the image forming operation mode.

[0145] In this embodiment, the image forming operation mode is used to indicate the current imaging requirements. For example, the image forming operation mode may include a monochrome image forming operation mode and a color image forming operation mode. In the monochrome image forming operation mode, the image forming apparatus typically only needs to use consumables of the color corresponding to the monochrome image to participate in imaging; in the color image forming operation mode, the image forming apparatus typically needs to use consumables of multiple different colors to work together to complete imaging.

[0146] In this step, the image forming apparatus identifies the consumables that need to participate in the imaging process based on the current image forming operation mode, and designates these consumables as target consumables. This method clarifies which consumables need to be used in the current imaging task and which do not require participation.

[0147] Step S1802: Control the magnetic unit of the target consumable to switch to the first state, so that the magnetic unit in the target consumable and the high voltage switching unit corresponding to the target consumable in the image forming apparatus form a magnetic interaction, thereby enabling the high voltage switching unit corresponding to the target consumable to conduct the high voltage power supply unit corresponding to the target consumable.

[0148] By switching the magnetic unit of the target consumable to the first state, the high-voltage power supply unit corresponding to the target consumable is turned on, thereby providing high-voltage power supply to the target consumable and meeting the high-voltage requirements of the current image forming operation for the target consumable.

[0149] Since this step only performs high-voltage power supply control on the target consumable, other consumables not selected as the target consumables will not be supplied with high-voltage power, thus preventing irrelevant consumables from being subjected to high voltage when not in operation.

[0150] See Figure 19 This is a schematic flowchart illustrating another control method for an image forming apparatus provided in an embodiment of this application. The method is... Figure 18 Based on the illustrated embodiment, the following steps are also included.

[0151] Step S1901: Control the magnetic units of the other consumables (excluding the target consumable) in the multiple consumables to switch to the second state, so that the magnetic units in the other consumables are disconnected from the magnetic interaction with the high voltage switching units corresponding to the other consumables in the image forming apparatus, thereby causing the high voltage switching units corresponding to the other consumables to disconnect the high voltage power supply units corresponding to the other consumables.

[0152] Specifically, among multiple consumables, those other than the target consumable can be referred to as "non-target consumables". By switching the magnetic unit of the non-target consumable to the second state, it can be ensured that the non-target consumable does not participate in the imaging work in the current image forming operation mode, and its corresponding high-voltage power supply unit is disconnected, thereby avoiding the application of high-voltage power supply to non-working consumables.

[0153] In this embodiment, by selectively determining the target consumable based on the image forming operation mode and controlling the conduction of only the high-voltage power supply unit corresponding to the target consumable, the image forming apparatus can achieve refined high-voltage power supply management in multi-consumable application scenarios. On the one hand, it can avoid consumables not involved in imaging being subjected to high voltage for extended periods, reducing the risk of imaging component malfunction or performance degradation; on the other hand, it can improve the utilization efficiency of high-voltage power supply, which is beneficial to improving the imaging stability and overall reliability of the image forming apparatus.

[0154] Based on the above-mentioned multi-consumable control scheme, the embodiments of this application further expand the explanation of the correspondence between magnetic units and color channels.

[0155] In practical applications, the correspondence between magnetic units and color channels is not one-to-one. One magnetic unit can correspond to consumables for one color channel or multiple color channels simultaneously. By configuring the correspondence between magnetic units and color channels differently, it is possible to meet imaging control requirements while balancing system complexity and control accuracy.

[0156] The following uses a color image forming apparatus that includes four color channels: cyan, magenta, yellow, and black, as an example to illustrate different implementation methods.

[0157] First implementation method: The image forming apparatus includes a magnetic unit that simultaneously controls the high-voltage power supply units corresponding to the three color channels: cyan, magenta, and yellow.

[0158] In this implementation, the color image forming apparatus can treat the imaging components corresponding to cyan, magenta, and yellow as a single color imaging circuit, with their high-voltage power supply states uniformly controlled by a single magnetic unit. When color imaging is required, the magnetic unit switches to a first state, turning on the corresponding high-voltage power supply unit; when color imaging is not required, the magnetic unit switches to a second state, turning off the corresponding high-voltage power supply unit. This method reduces the number of magnetic units and simplifies the system structure.

[0159] The second implementation method: The image forming apparatus is equipped with two magnetic units. One magnetic unit is used to control the high-voltage power supply unit corresponding to the three color channels of cyan, magenta and yellow, and the other magnetic unit is used to control the high-voltage power supply unit corresponding to the black color channel.

[0160] By controlling the color and black channels separately, the black channel can be managed independently while maintaining a relatively simplified system structure. For example, in black-and-white imaging mode, only the high-voltage power supply unit corresponding to the black channel needs to be activated, while the high-voltage power supply unit corresponding to the color channel does not need to be activated, thereby further reducing unnecessary high-voltage application.

[0161] The third implementation method: The image forming apparatus is equipped with three magnetic units, which are used to control the high-voltage power supply units corresponding to the three color channels: cyan, magenta, and yellow.

[0162] In this implementation, the high-voltage power supply unit for each color channel can be controlled independently, allowing the image forming apparatus to flexibly select the color channels to participate in the operation according to actual imaging needs. For example, in partial color imaging or special imaging modes, only some color channels are supplied with high-voltage power, thereby improving control flexibility.

[0163] The fourth implementation method: The image forming apparatus is equipped with four magnetic units, which are used to control the high-voltage power supply units corresponding to the four color channels: cyan, magenta, yellow, and black.

[0164] By configuring an independent magnetic unit for each color channel, precise control of the high-voltage power supply for each color channel can be achieved. This allows the consumables for each color channel to have their high-voltage power supply turned on or off individually according to the corresponding imaging task, making it suitable for application scenarios with high requirements for imaging accuracy and stability.

[0165] By configuring various magnetic units and color channels as described above, the number and control granularity of magnetic units can be flexibly selected according to the structural design and application requirements of different image forming apparatuses. On the one hand, this reduces system structural complexity and control costs while ensuring image quality; on the other hand, it enables refined high-voltage power supply management for consumables in different color channels, avoiding unnecessary high-voltage application, thereby further improving the reliability and imaging stability of the image forming apparatus.
