Technical Field

[0001] This application relates to the technical field of image forming apparatus, and more particularly to an image forming apparatus and its control method, control device and storage medium. Background Technology

[0002] During operation, the printer's drive unit needs to rotate continuously in the same direction to provide driving force to the corresponding components. However, this continuous rotation can easily lead to excessive gear pressure on the photosensitive drum's drive unit, increasing the drive unit's torque and potentially damaging the equipment or even affecting image quality. Summary of the Invention

[0003] This application provides an image forming apparatus and its control method, control device and storage medium. The method allows the image forming apparatus to transfer residual toner on the surface of the photosensitive drum to the cleaning blade after the consumables have been preheated and stirred or after the paper jam has been cleaned. The cleaning blade can then clean the residual toner, ensuring the quality of the printed image. At the same time, it reduces the pressure on the drive gear of the photosensitive drum and the torque of the drive unit.

[0004] In a first aspect, embodiments of this application provide a control method for an image forming apparatus, the image forming apparatus including a driving unit, the method comprising: when the image forming apparatus is in a first working state and a target event is detected to meet a preset condition, controlling the driving unit to rotate along a first direction at a first rotational speed for a first duration; after controlling the driving unit to rotate along the first direction at the first rotational speed for the first duration, waiting for a second duration, and after the second duration, controlling the driving unit to rotate along a second direction at a first rotational speed or a second rotational speed lower than the first rotational speed; wherein the first direction is different from the second direction.

[0005] In one possible implementation, when the image forming apparatus is in a first working state and a target event is detected to meet a preset condition, controlling the drive unit to rotate along the first direction at a first speed for a first duration includes: when the image forming apparatus is in a power-on state or a preheating and stirring state, if it is detected that a cover of the image forming apparatus is opened and then closed, or if it is detected that the image forming apparatus is awakened, then controlling the drive unit to rotate along the first direction at a first speed for a first duration.

[0006] In one possible implementation, when the image forming apparatus is in a first working state and a target event is detected to meet a preset condition, controlling the drive unit to rotate along the first direction at a first speed for a first duration further includes: when the image forming apparatus is in a standby state or a cleaning state and a fixing temperature inside the image forming apparatus is detected to reach a preset temperature threshold, then controlling the drive unit to rotate along the first direction at a first speed for a first duration; or when the image forming apparatus is in a preheating and stirring state and a command is received that the consumable components of the image forming apparatus have completed stirring, then controlling the drive unit to rotate along the first direction at a first speed for a first duration.

[0007] In one possible implementation, the first duration is shorter than the second duration, and the durations of the first and second durations are inversely related to the printing speed of the image forming device.

[0008] In one possible implementation, the printing speed is positively correlated with the rotational speed of the drive unit.

[0009] In one possible implementation, the first direction is counterclockwise and the second direction is clockwise.

[0010] In one possible implementation, the second rotational speed is 1 / 2 of the first rotational speed, or the second rotational speed is 3 / 4 of the first rotational speed.

[0011] Secondly, embodiments of this application also provide an image forming apparatus control device. The image forming apparatus includes a driving unit. The device may include a state detection module, an event detection module, and a driving control module. The driving control module includes the driving unit. The state detection module is used to acquire a first working state of the image forming apparatus. The event detection module is used to detect whether a target event meets a preset condition and send the detection result to the driving control module. The driving control module is used to control the driving unit to rotate along a first direction at a first rotational speed for a first duration when the detection result is determined to meet the condition. It is also used to control the driving unit to rotate along a second direction at a first rotational speed or a second rotational speed lower than the first rotational speed after waiting for a second duration. The first direction is different from the second direction.

[0012] Thirdly, embodiments of this application also provide a control device for an image forming apparatus, including a processor and a memory, wherein the memory is used to store at least one instruction, which, when loaded and executed by the processor, implements the control method for the image forming apparatus provided in the first aspect.

[0013] Fourthly, embodiments of this application also provide an image forming apparatus, including the image forming apparatus control device provided in the third aspect.

[0014] Fifthly, embodiments of this application also provide a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the control method of the image forming apparatus provided in the first aspect.

[0015] In a sixth aspect, embodiments of this application also provide a computer program product, including a computer program or instructions, which, when executed by a processor, implement the control method of the image forming apparatus provided in the first aspect.

[0016] The above technical solution allows the image forming equipment to control the drive unit to reverse for a certain period of time after it has entered a different working state, so that the residual toner on the surface of the photosensitive drum can be transferred to the cleaning blade and cleaned by the cleaning blade, ensuring the quality of the printed image. At the same time, it reduces the pressure on the photosensitive drum gear and the torque of the drive unit. Then, the drive unit is controlled to rotate forward to provide the corresponding driving force for subsequent operations of the image forming equipment. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Figure 1 This is a schematic diagram of an image forming apparatus structure provided in one embodiment of this application.

[0025] Please see Figure 1 The image forming apparatus 100 is used to perform image forming jobs, and examples of the image forming apparatus 100 include printers, scanners, copiers, fax machines, and multi-functional peripherals (MFPs) that can perform functions such as receiving images and printing images in a single device.

[0026] As an example of an image forming apparatus 100, the image forming apparatus 100 includes a photosensitive drum 101Y-K, a charging roller 102Y-K, a developing roller 103Y-K, a toner hopper 104Y-K, a transfer belt 105, a secondary transfer roller 106, a paper feed tray 107, a manual paper feed tray 108, a paper feed roller 109, a transfer roller 110, a paper detection sensor 120, a laser scanning unit (LSU) 111, a fixing roller (including a heating roller 112 and a pressure roller 113), an ejector roller 114, and an ejector tray 115, etc. Generally, the processing cartridge CM includes a photosensitive drum 101Y-K, a charging roller 102Y-K, a developing roller 103Y-K, and a toner hopper 104Y-K for holding toner.

[0027] LSU 111 is a single LSU comprising four optical paths. Four charging rollers 102Y-K charge the surfaces of the four photosensitive drums 101Y-K respectively. The four optical paths of LSU 111 emit laser beams to form electrostatic latent images on the surfaces of the photosensitive drums 101Y-K. Four developing rollers 103Y-K develop toner images of a single color on the surfaces of the photosensitive drums 101Y-K respectively. The image forming apparatus 100 employs a two-stage transfer method: the four photosensitive drums 101Y-K sequentially transfer the toner image onto the transfer belt 105, and then the colored toner image formed on the transfer belt 105 is transferred a second time onto the paper via the secondary transfer roller 106. The paper tray 107 stores the paper, and the paper feed roller 109 transports the stored paper to the transport path (i.e., the paper path channel described later). The conveyor roller 110 transports the paper to the secondary transfer roller 106.

[0028] The secondary transfer roller 106 transports the imaged paper to the clamping area of ​​the hot roller 112 and the pressure roller 113. The hot roller 112 and the pressure roller 113 are used to fix the toner image on the paper. The hot roller 112 can be heated by ceramic heating. The hot roller 112 and the pressure roller 113 transport the fixed paper to the discharge roller 114. The discharge roller 114 discharges the paper into the discharge tray 115 and stacks it up.

[0029] The laser scanning unit 111 acquires an optical analog image signal of the original / source document through exposure of the light printhead. The paper detection sensor 120 is used to detect whether there is paper in the paper path at its location.

[0030] The paper feed cassette 107 is provided with a paper outlet. The paper feed roller 109 is specifically used to feed the paper contained in the paper feed cassette 107 from the paper outlet into the paper path for transfer requirements. The image forming apparatus 100 also includes a drive mechanism (not shown) for driving the paper feed roller 109. The drive mechanism is a drive motor used to drive the paper feed roller 109 to move, thereby realizing the paper feeding operation. The drive mechanism 181 is electrically connected to the controller (not shown) of the image forming apparatus to realize the controller's operation control of the drive mechanism. The controller is electrically connected to the paper detection sensor 120, which sends the detection result information of whether there is paper in the paper path to the controller.

[0031] The image forming apparatus 100 also includes an operation panel (not shown), which includes an operation section consisting of various keys (not shown) and a touchpad-type display section (not shown).

[0032] It is understood that the image forming apparatus 100 listed above is only an example, and the component configuration and component arrangement of the image forming apparatus 100 can be adjusted according to the actual situation without affecting the improvement idea of ​​the present invention.

[0033] In some embodiments, the image forming apparatus provided in this application further includes a driving unit, which can be used for... Figure 1 The drive motor in the image forming apparatus shown provides driving force for the image forming apparatus to perform tasks such as printing, scanning, and copying. This drive unit can provide forward driving force by rotating clockwise and reverse driving force by rotating counterclockwise.

[0034] Figure 2 This is a flowchart of a control method for an image forming apparatus provided in one embodiment of this application.

[0035] Reference Figure 2 As shown, the method may include the following steps:

[0036] S201: When the image forming device is in the first working state and a target event is detected to meet the preset conditions, the control drive unit is rotated along the first direction at a first speed for a first duration.

[0037] In some applications, the image forming device enters a power-on state upon connection to a power source and startup. If no operation command is detected within a preset time after startup, the image forming device enters a sleep state. During the process of receiving and executing a print job, the image forming device sequentially goes through the following states: preheating state, stirring state, ready state, imaging state, and cleaning state. In some embodiments, the preheating state and stirring state can be combined into one state, namely the preheating and stirring state. The ready state can also be understood as a standby state. In this preheating and stirring state, the image forming device heats the fixing component (such as the fixing roller) and stirs the printing consumables (such as the toner cartridge). During the heating of the fixing component, it detects whether the temperature of the fixing component has reached a preset temperature threshold (i.e., determines whether the fixing temperature has reached the preset temperature threshold). If the preset temperature threshold is reached based on the detection result, heating is stopped. Furthermore, after the printing consumables (such as the toner cartridge) have finished stirring, a command indicating that the consumable component has completed stirring is generated. Upon detecting this command, the image forming device stops stirring the printing consumables. After the image forming apparatus completes the imaging process, the imaging components inside the image forming apparatus can be cleaned. For example, residual toner on the surface of the photosensitive drum can be cleaned to improve the quality of the next image.

[0038] In some embodiments, the first working state may include a power-on state, a preheating and stirring state, a standby state, and a cleaning state.

[0039] In some embodiments, the target event of the image forming apparatus may include an apparatus cover opening / closing event, a wake-up event, a fixing heating event, and a consumable stirring event, etc. This target event is used to indicate whether a designated drive unit rotates along a first direction.

[0040] In some embodiments, the image forming apparatus can detect whether a target event meets preset conditions. Specifically, when it is detected that the front or right cover of the image forming apparatus housing has been opened and then closed, the apparatus cover opening / closing event can be confirmed as meeting preset conditions. When it is detected that the image forming apparatus has received an operation command, i.e., been awakened, the awakening event can be confirmed as meeting preset conditions. When it is detected that the fixing temperature within the image forming apparatus has reached a preset temperature threshold, the fixing heating event can be confirmed as meeting preset conditions. When it is detected that the consumable components of the image forming apparatus have responded with a stirring completion command, the consumable stirring event can be confirmed as meeting preset conditions.

[0041] In some embodiments, when the image forming apparatus is in a first working state and a target event is detected to meet a preset condition, controlling the drive unit to rotate along the first direction at a first rotation speed for a first duration may include: when the image forming apparatus is in a power-on state or a preheating and stirring state, if a cover of the image forming apparatus is detected to be opened and then closed, or if the image forming apparatus is detected to be awakened, then controlling the drive unit to rotate along the first direction at a first rotation speed for a first duration.

[0042] In this embodiment, when the image forming device is in a powered-on state or a preheating and stirring state, it can detect whether the device cover opening and closing event or the wake-up event meets the preset conditions. When the device cover opening and closing event or the wake-up event meets the preset conditions, it can control the drive unit to rotate along the first direction at a first speed for a first duration.

[0043] In one embodiment, the detection of whether the cover of the image forming apparatus is opened and then closed can be the detection of whether the paper feed cover and the fixing protection cover of the image forming apparatus are opened and then closed.

[0044] The image forming apparatus includes a main body, an imaging unit, and a fixing unit. The imaging unit and fixing unit are housed within the main body. A paper discharge cover is provided at the upper opening of the main body to close the opening, thus preventing the imaging unit from being exposed to the opening. A fixing protective cover is provided on the paper discharge cover to protect the fixing unit. In the event of a paper jam, the user needs to open the fixing protective cover to remove the obstructing paper. After opening the paper discharge cover, the fixing unit is disconnected from electrical connection.

[0045] In one embodiment, sensors can be installed at the positions of the paper feed cover and the fuser cover of the image forming apparatus, and the opening / closing state of the paper feed cover and the fuser cover can be determined by the sensing data from these sensors. In other embodiments, the opening / closing state of the paper feed cover and the fuser cover of the image forming apparatus can also be detected by other means. This application does not limit the method of detecting the opening / closing state of the paper feed cover and the fuser cover of the image forming apparatus.

[0046] In one implementation, the image forming device is triggered to wake up when it receives a print job from another connected terminal device or cloud platform, i.e., a wake-up event is triggered. In another implementation, the image forming device can be automatically woken up when its sleep time reaches a preset sleep time, which can also trigger the image forming device to wake up. In other implementations, the image forming device can also be woken up in response to user operation when it is in sleep mode. For example, a user clicking any button on the control panel of the image forming device can trigger the image forming device to wake up.

[0047] It should be noted that the embodiments of this application do not limit the method of triggering the image forming device to wake up. In other embodiments, the image forming device can also be woken up in other ways.

[0048] In other embodiments, when the image forming apparatus is in a first working state and a target event is detected to meet a preset condition, controlling the drive unit to rotate along the first direction at a first speed for a first duration further includes: when the image forming apparatus is in a standby state or a cleaning state, if the fixing temperature inside the image forming apparatus is detected to reach a preset temperature threshold, then controlling the drive unit to rotate along the first direction at a first speed for a first duration; or when the image forming apparatus is in a preheating and stirring state, if a command is received that the consumable components of the image forming apparatus have completed stirring, then controlling the drive unit to rotate along the first direction at a first speed for a first duration.

[0049] In one embodiment, the heating temperature of the fixing component can be obtained by a temperature sensor located at the fixing component of the image forming apparatus. When the obtained heating temperature reaches a preset temperature threshold (i.e., the fixing temperature inside the image forming apparatus is detected to have reached the preset temperature threshold), it can be confirmed that the fixing heating event meets the preset conditions, and then the drive unit can be controlled to rotate along the first direction at a first rotation speed for a first duration. It should be noted that this application embodiment does not limit the method of obtaining the fixing temperature; in other embodiments, other detection methods can be used to determine the fixing temperature.

[0050] In this embodiment, when the image forming device is in standby or cleaning state, it can detect whether the fixing heating event meets the preset conditions. When the fixing heating event meets the preset conditions, it can control the drive unit to rotate along the first direction at the first speed for the first duration.

[0051] In some embodiments, when the image forming apparatus is in a preheating and stirring state, it can also detect whether the consumable stirring event meets a preset condition. When the consumable stirring event meets the preset condition, it can control the drive unit to rotate along the first direction at a first speed for a first duration.

[0052] In some embodiments, the target event may further include a paper jam event. It should be noted that when the image forming apparatus detects a paper jam event that meets preset conditions in any state, it can control the drive unit to rotate along a first direction at a first rotational speed for a first duration. In one embodiment, when the image forming apparatus confirms a paper jam, it can confirm that the paper jam event meets the preset conditions. Furthermore, this application does not limit the method by which the image forming apparatus confirms a paper jam.

[0053] In some embodiments, the first direction may be counterclockwise. In one embodiment, the first rotational speed may be the rotational speed of the drive unit in the default printing mode of the image forming apparatus. In other embodiments, the first rotational speed may also be the rotational speed of the drive unit in other operating modes of the image forming apparatus, and this application does not limit this.

[0054] When the image forming apparatus is detected in the first working state by any of the methods provided in the embodiments of this application, and the target event is detected to meet the preset conditions, the drive unit is controlled to rotate counterclockwise at a first speed for a first duration. This can transfer the residual toner on the surface of the photosensitive drum to the cleaning blade, which can then clean it, thereby improving the quality of the image printed in the next printing. At the same time, it reduces the pressure on the drive gear of the photosensitive drum and reduces the torque of the drive unit.

[0055] S202: After the control drive unit rotates along the first direction at a first speed for a first duration, wait for a second duration. After the second duration, the control drive unit rotates along the second direction at a first speed or a second speed lower than the first speed.

[0056] In some embodiments, the drive unit can be controlled to rotate along a first direction at a first rotational speed, and a first time can be recorded for a first duration, allowing the drive unit to rotate at the first rotational speed for the first duration. Then, the timer is restarted for a second duration, during which the drive unit is controlled to stop rotating. It should be noted that the purpose of stopping the drive unit for the second duration is to allow the rotational speed of the drive unit and the rotational speed of the components driven by the drive unit to drop below a preset speed, thereby providing the conditions for subsequent forward rotation of the drive unit and preventing damage to the components from sudden forward rotation when the drive unit or the driven components are in high-speed reverse rotation.

[0057] After a second time interval, the drive unit can be controlled to rotate along a second direction at a first rotational speed or a second rotational speed lower than the first rotational speed. The first direction is different from the second direction. In one embodiment, the first direction is opposite to the second direction; for example, if the first direction is counterclockwise (i.e., reverse rotation), then the second direction is clockwise (i.e., forward rotation). In other words, when the drive unit rotates along the first direction, it is in reverse rotation, and when the drive unit rotates along the second direction, it is in forward rotation. In some embodiments, the second rotational speed is half the first rotational speed; that is, when the drive unit is controlled to rotate at the second rotational speed, it is a half-speed rotation. In other embodiments, the second rotational speed can also be other speeds such as one-third or three-quarters of the first speed; this application does not limit the second rotational speed.

[0058] In some embodiments, at the same printing speed, the first duration of the drive unit reversing is shorter than the second duration of the drive unit stopping rotation. However, at different printing speeds, the durations of the first and second times are inversely related to the printing speed of the image forming apparatus; that is, the higher the printing speed, the shorter the first duration of the drive unit reversing and the second duration of the drive unit stopping rotation. The printing speed is positively related to the rotational speed of the drive unit; the higher the printing speed, the higher the rotational speed of the drive unit. The image forming apparatus can set the printing speed based on user operation, and the rotational speed of the drive unit varies at different printing speeds. This printing speed may include a first printing speed (i.e., a normal printing speed), a second printing speed (medium printing speed), and a third printing speed (low printing speed). The first rotational speed of the drive unit corresponding to the first printing speed is greater than the second rotational speed of the drive unit corresponding to the second printing speed, and also greater than the third rotational speed of the drive unit corresponding to the third printing speed.

[0059] In other embodiments, steps S201 and S202 are executed when the image forming device does not receive a print job. Specifically, during S202, the drive unit can be controlled to rotate along a second direction at a first rotational speed or a second rotational speed lower than the first rotational speed for a third duration. For example, when the printer is currently in a sleep state, in response to user operation, the printer triggers a wake-up (i.e., detects that a target event meets preset conditions), and then the printer's drive unit can be controlled to rotate counterclockwise at full speed (i.e., the first rotational speed) for a first duration. After completing the first duration of rotation, it waits for a second duration before stopping rotation. After the second duration, the printer's drive unit is controlled to rotate clockwise at full speed (i.e., the first rotational speed) or half speed (i.e., the second speed) for a third duration before stopping rotation. The third duration can be a preset time length, and the third duration can be longer than the second duration.

[0060] In some embodiments, at the same printing speed, the first printing time is less than the second printing time, which is less than the third printing time. Furthermore, the first, second, and third printing times have different values ​​at different printing speeds. For example, the first printing speed > the second printing speed > the third printing speed. Specifically, at the first printing speed, the first printing time is Ta1; at the second printing speed, the first printing time is Tb1; at the third printing speed, the first printing time is Tc1, and Ta1 < Tb1 < Tc1. At the first printing speed, the second printing time is Ta2; at the second printing speed, the second printing time is Tb2; at the third printing speed, the second printing time is Tc2, and Ta2 < Tb2 < Tc2. At the first printing speed, the third printing time is Ta3; at the second printing speed, the third printing time is Tb3; at the third printing speed, the third printing time is Tc3, and Ta3 < Tb3 < Tc3.

[0061] In some embodiments, the rotation of the drive unit can be controlled by a pulse signal.

[0062] Figure 3 This is a schematic diagram of the pulse signal of the control drive unit provided in one embodiment of this application.

[0063] Reference Figure 3 As shown, when the drive unit is powered on, the corresponding pulse signal is in a high-level state. When the image forming device in its first operating state detects a target event that meets a preset condition, the pulse signal switches to a low-level state and remains there for a first duration. In response to the low-level pulse signal of this first duration, the drive unit rotates along the first direction at a first rotational speed for a first duration T1 (i.e., reverses the first rotational speed for the first duration T1). After the drive unit completes the reversal of the first duration, the pulse signal switches to a high-level state and remains there for a second duration T2, so as to control the drive unit to stop rotating within the second duration, causing its rotational speed to decrease or fall below a preset rotational speed. After this second duration, the pulse signal switches to a low-level state, thereby controlling the drive unit to rotate along the second direction (forward) at a first rotational speed or a second rotational speed less than the first rotational speed, until the image forming device completes the printing operation, and the pulse signal switches back to a high-level 0V state.

[0064] Figure 4 This is a schematic diagram of the structure of an image forming apparatus control device provided in one embodiment of this application.

[0065] Reference Figure 4 As shown, the device may include a state detection module 401, an event detection module 402, and a drive control module 403. The drive control module includes a drive unit. The state detection module is used to acquire a first working state of the image forming device. The event detection module is used to detect whether a target event meets a preset condition and send the detection result to the drive control module. The drive control module is used to control the drive unit to rotate along a first direction at a first rotation speed for a first duration when the detection result is confirmed to meet the condition. It is also used to control the drive unit to rotate along a second direction at a first rotation speed or a second rotation speed lower than the first rotation speed after waiting for a second duration. The first direction is different from the second direction.

[0066] In one possible implementation, when the state detection module 401 detects that the image forming device is in a first working state and the event detection module 402 detects that the target event meets the preset conditions, the drive control module controls the drive unit to rotate along the first direction at a first speed for a first duration, including: when the state detection module 401 detects that the image forming device is in a power-on state or a preheating and stirring state, the event detection module 402 detects that a cover of the image forming device is opened and then closed, or detects that the image forming device is woken up, the drive control module 403 controls the drive unit to rotate along the first direction at a first speed for a first duration.

[0067] In one possible implementation, when the state detection module 401 detects that the image forming device is in a first working state and the event detection module 402 detects that the target event meets the preset conditions, the drive control module controls the drive unit to rotate along the first direction at a first speed for a first duration, including: when the state detection module 401 detects that the image forming device is in a striking state or a cleaning state, the event detection module 402 detects that the fixing temperature of the image forming device has reached a preset temperature threshold and the printing consumables of the image forming device have been stirred, the drive control module 403 controls the drive unit to rotate along the first direction at a first speed for a first duration; or when the state detection module 401 detects that the image forming device is in a preheating and stirring state, the event detection module 402 receives an instruction that the consumable components of the image forming device have completed stirring, the drive control module 403 controls the drive unit to rotate along the first direction at a first speed for a first duration.

[0068] In one possible implementation, the first duration is shorter than the second duration, and the durations of the first and second durations are inversely related to the printing speed of the image forming device.

[0069] In one possible implementation, the printing speed is positively correlated with the rotational speed of the drive unit.

[0070] In one possible implementation, the first direction is counterclockwise and the second direction is clockwise.

[0071] In one possible implementation, the second rotational speed is 1 / 2 of the first rotational speed, or the second rotational speed is 3 / 4 of the first rotational speed.
