These drawings and the accompanying description are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0055] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0056] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0057] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "fixed," and the like should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication between them; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0058] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0059] In the above description, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.

[0060] In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification, as well as features of different embodiments or examples, unless they are mutually inconsistent.

[0061] Imaging devices (such as inkjet printers and laser printers) typically have relatively long lifespans. Therefore, when the consumable materials (e.g., ink, toner, etc.) in a printing consumable cartridge (e.g., an ink cartridge with a print head, a toner cartridge, or a photosensitive drum) are used up, a new cartridge must be replaced for continued use. The lifespan of a printing consumable cartridge is shorter than, or even significantly shorter than, the lifespan of the imaging device. These printing consumable cartridges contain printing components, such as a print head and a drum unit, that are used to print text or images. These printing components are integrated into the consumable cartridge and can be replaced with each replacement of the consumable cartridge.

[0062] Imaging equipment manufacturers hope that trusted printing consumables cartridges will be used in their imaging equipment, because the use of untrusted printing consumables cartridges may affect the quality of the imaging equipment, threaten safety, deteriorate print quality, etc., resulting in customer losses or irreversible consequences, affecting the customer experience.

[0063] Furthermore, under many conditions, printing consumables cartridges cannot simply be refilled with consumables and continued to be used. For example, a damaged heater resistor in the print head prevents the corresponding nozzle from ejecting ink, which can affect print quality. Ink can corrode circuit components, resistors, or wires in the print head, causing open or short circuits. A crack in the print head makes it unsuitable for continued printing. A clogged flow path or nozzle can prevent ink ejection. In other examples, damage to the photosensitive component of the photosensitive drum prevents normal printing or affects print quality. Given these numerous non-reusable conditions, it is highly undesirable for untrusted third parties to continue to market repaired printing consumables and use them in imaging devices.

[0064] Currently, there are two common technical approaches to prevent untrusted third parties from reusing repaired printing consumables cartridges in imaging devices:

[0065] First, a disposable structure is provided on the consumable cartridge. Upon initial use or when the consumable material is depleted, the structure changes state, rendering it unusable. For example, a consumable cartridge may have such a structure that, when the consumable cartridge is loaded into an imaging device, the imaging device rotates the printing consumable cartridge, causing the structure to change from a first state to a second state. Once in the second state, the structure cannot be restored. Consequently, when the consumable cartridge is reloaded with consumable material or partially restored after stored data is restored, the imaging device does not detect the change from the first state to the second state and therefore refuses to use the consumable cartridge.

[0066] For another example, the consumable box is provided with readable information (such as a QR code, RFID, NFC data, etc.) that can be destroyed. When the consumable box is used for the first time, the readable information can be read. After the consumable box is loaded into the imaging device, the readable information is destroyed. When the consumable box is loaded into the imaging device for use again, the imaging device does not detect the readable information and thus refuses to use the consumable box. However, this external structure that prevents continued use is easy to imitate, and then the imitated structure replaces the original structure. In this way, the imaging device can continue to use the consumable box because it detects the required status or information. This external structure is easy to imitate and replace, so the effect is not obvious. Therefore, the second anti-reuse method is more often used.

[0067] The second is to use communication authentication methods, such as serial number, encryption authentication, etc. For example, a serial number (such as ID) is stored in the chip of the consumable box. The serial number is unique. When the imaging device reads the serial number, if it matches the serial number of the consumable box in its database, the authentication is passed. When the consumable material in the consumable box is exhausted, the imaging device will rewrite the corresponding data in the memory to the exhausted state (for example, storing 1111 1111 in a certain memory address means that the consumable material is exhausted and cannot be used. Of course, other forms can also be used to represent the exhausted state). When the consumable material is transferred back into the consumable box, the consumable box is rejected because the data in the memory is in the exhausted state. In order to reuse the consumables cartridge, an untrusted third party may add a repair chip that reproduces the serial number or simulates a serial number that can be recognized by the imaging device, and rewrites the corresponding consumable level in the same memory address to a usable state (for example, storing 0000 0000 in the same memory address means that the consumables are full, or at least usable). When such a printing consumables cartridge is reinstalled in the imaging device, the serial number and consumable level data meet the requirements, and thus the consumables cartridge can continue to be used.

[0068] For example, a session key is stored in the consumable cartridge chip. The imaging device communicates with the printing consumable cartridge based on this session key, or encrypts and decrypts data using an encryption algorithm to prevent untrusted third parties from learning the meaning of the data in the memory. However, if the encryption algorithm module is completely copied and the data in the memory is reproduced, the repaired consumable cartridge will still be recognized by the imaging device as a normal printing consumable cartridge and can continue to be used. Moreover, with the increasing sophistication of reverse engineering technology, the possibility of obtaining data and algorithms is also increasing. The data reading or operation rules of the imaging device can also be easily cracked, thereby imitating the imaging device's operation rules, regenerating data and writing it to the memory. As a result, the consumable cartridge will still be recognized by the imaging device as a normal printing consumable cartridge and can continue to be used. In this way, untrusted third parties can still repair the modified printing consumable cartridge and continue to use it.

[0069] The following describes in detail the technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems using specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following embodiments of the present invention are described in conjunction with the accompanying drawings.

[0070] The present invention provides an imaging device that aims to solve the aforementioned technical problems of the prior art. It is applied to the field of imaging device technology, specifically the field of imaging device component disposal technology, to address the existing problem of untrusted third parties reproducing or repairing discarded printing components.

[0071] Figure 1 FIG. 1 is a schematic diagram of an imaging device according to an embodiment of the present invention. Figure 1 As shown, the imaging device 1 includes: a main control module 11 and a main body 12 connected thereto, wherein:

[0072] The main body 12 is internally provided with a mounting portion for accommodating a consumables box (ie, a printing consumables box) 2 . The mounting portion is provided with a destruction structure 102 , wherein the destruction structure 102 is used to destroy the printing component 22 in the consumables box 2 .

[0073] The main control module 11 is connected to the destruction structure 102 and is used to control the destruction structure 102 to irreversibly destroy the printing component when the consumable box 2 reaches a specified discard condition, so that the printing component has printing defects.

[0074] Optionally, the imaging device 1 can accommodate one or more consumable boxes 2, and a printing component 22 (for example, a print head, a photosensitive drum, etc.) is provided in the consumable box 2, and a destruction structure 102 is provided in the imaging device. Optionally, in an embodiment of the present invention, the destruction structure 102 can be in the form of a physical stress applying component to achieve irreversible damage to the printing component.

[0075] In one possible example, Figure 2 As shown, the consumable box 2 has a box body, a printing component 22, and the box body is used to accommodate consumable materials (such as ink, toner, etc., and when it is a photosensitive drum, it is used to accommodate a photosensitive drum unit or can also accommodate waste toner). The consumable materials can be sprayed or transferred to a printing medium 3 (such as paper, plastic, cloth, etc.) under the action of the printing component 22 to form the required text or image.

[0076] For example, Figure 2 The ink cartridge structure with a print head shown in the figure has an ink supply channel and an ejection chamber provided on the printing component 22. The ink supply channel supplies the ink contained in the box body of the consumable cartridge 2 to the ejection chamber. The ejection chamber is provided with an ejection element (such as a heating resistor, a pressure-sensitive element, etc.) and an inkjet hole. When the ejection element is stimulated, the ink in the ejection chamber can be ejected from the ejection hole to form the desired image or text.

[0077] In an embodiment of the present invention, the printing component 22 is controlled by the main control module 11 to perform a spraying or transfer action, that is, a printing action. For example, the main control module 11 receives the printing data signal, clock signal, address signal, activation signal, etc. from the imaging device 1, and then activates the spray element at the specified address of the printing component 22 to perform printing based on the received signal.

[0078] like Figure 3 As shown, in another possible example, in addition to the printing component 22, the destruction structure 102, etc., the consumable end, that is, the consumable box, may also be provided with various types of sensors (such as consumable level sensor 251, temperature sensor 252, crack sensor 253, bubble sensor 254, etc.) and corresponding sensor detection circuits 25. These sensors can be integrated into the printing component 22 and the print control module 23, or they can be independent modules, becoming another independent chip or circuit. Here, these circuits at the printing consumable end such as the printing component 22, the print control module 23, the sensors, the sensor detection circuit 25, etc. are collectively referred to as consumable circuits. These consumable circuits can be independent or integrated. When the consumable box 2 does not have various functional modules such as sensors and sensor detection circuits 25, and only has the printing component 22 and the print control module 23 for completing the printing action, the printing component 22 and the print control module 23 can be consumable circuits.

[0079] Optionally, the main control module 11 is used to obtain data information of the consumable circuit, and when it is detected that the data information reaches a specified discard condition, it controls the destruction structure 102 to irreversibly destroy the printing component so that the printing component has a printing defect.

[0080] In a possible example, the above-mentioned specified discarding conditions include any one or more of the following situations: exhaustion state, short circuit or disconnection or open circuit, cracks, blockage, abnormal temperature, reaching the specified number of uses, and reaching the specified usage time.

[0081] In another possible example, the printing defects include any one or more of the following: failure to print data, incorrect print data, missing print data, broken print data, streaks in printing, ghosting of print data, too light print data, or too dark print data.

[0082] For example, when the print head reaches a specified discard condition, the main control module 11 controls the destruction structure 102 to apply physical stress to the printing components. The degree of physical stress applied should be sufficient to cause irreversible physical damage to the printing components, resulting in visible printing defects and unacceptable printing results for customers. When the printing components suffer irreversible physical damage, even recycled consumables cannot be simply reused through external structural replacement and reproduction, communication authentication, etc., thereby preventing the continued use of unauthorized repaired consumables. Furthermore, it prevents consumables that have reached the scrap standard from being used again after repair, which would harm customer interests.

[0083] It is understandable that when these printing components are irreversibly damaged, even if the consumable box 2 has passed the certification of the imaging device 1, the printing effect will be greatly reduced or even unable to print, so it cannot continue to be put into market use. Therefore, it completely solves the problem of an untrustworthy third party continuing to put the repaired consumable box 2 into the market for use, effectively preventing damage to the imaging device, reduction in printing quality, and damage to customer interests.

[0084] Illustratively, irreversible damage (e.g., physical damage) to the printing component can be partial or complete. For example, the entire printing component 22 may be burned, rendering all nozzles unable to eject ink. Alternatively, partial damage may occur, such as burning a specific area (e.g., the center, a column, the left side, the right side, or a combination thereof) of the printing component 22. In this case, even if some nozzles can still eject ink, the damaged area cannot, resulting in unacceptable printing results for the customer, thereby preventing the repaired consumable cartridge 2 from being released to the market. Alternatively, damage may occur to the entire circuit structure or a portion of the circuit structure of one or more components, such as the data receiving module, latches, registers, address generators, various arithmetic logic gates, switch controls, pre-charge circuits, and selection circuits, resulting in an inability to complete printing operations. Irreversible damage to the printing component results in unacceptable printing results for the customer. Unacceptable printing results refer to visually detectable printing defects. For example, the printing component may be short-circuited, broken, open-circuited, unable to receive data, unable to output data, outputting erroneous data, or unresponsive to signals. Unacceptable printing effects include the inability to print data, incorrect print data, missing print data, broken print data, stripes on the print, ghosting of print data, too light print data, too dark print data, etc. Unacceptable printing effects are obvious defects visible to the naked eye. For ordinary customers or consumers, such visible printing effects are unacceptable.

[0085] This approach avoids the problem of external structure being replaced and reproduced, and communication authentication methods being cracked, thereby preventing the continued use of untrusted repair consumable boxes 2 from the source. Moreover, it prevents the consumable boxes 2 that have reached the scrap standard from being used after being repaired, which would harm the interests of customers.

[0086] In a possible example, the destruction structure 102 includes:

[0087] The pressure applying member is used to apply pressure to the printing component from the bottom of the mounting portion when destroying the printing component, so as to physically break the printing component.

[0088] In one example, the destructive structure 102 includes a pressure-applying component, such as a rigid structure placed at the bottom of the mounting portion. When the imaging device determines that the consumable box needs to be physically destroyed, the rigid structure is lifted upward by a lifting component. The upward force causes the print head to shatter and cannot be used further.

[0089] Through the embodiments of the present invention, a pressure-applying member can be used to apply pressure to the printing component that is sufficient to damage the printing component, such as causing the printing component to be damaged, broken, or have gaps. This damage makes it impossible to complete normal printing operations, thereby outputting visible and unacceptable printing defects.

[0090] Schematically, the pressure-applying member is arranged at the basic middle position of the printing component. Since the middle position can withstand less stress and is more likely to break, it can ensure that the applied force can cause destructive damage. At the same time, the applied force is reduced, the stroke of the pressure-applying member can be shortened, and the occupied space can be reduced.

[0091] In another possible example, the above-mentioned destruction structure 102 further includes:

[0092] The cutting component is used to cut the printing component based on different cutting directions when destroying the printing component, so as to physically break the printing component.

[0093] In one example, the destruction structure 102 includes a cutting member that can move left and right and / or up and down, cutting the printed component during the movement to cause irreversible physical damage.

[0094] Optionally, the above-mentioned irreversible physical damage includes breakage, fracture, notch, thermal damage, and melting.

[0095] Illustratively, as an optional real-time method, the cutting member moves in the direction of the short side of the printed component. For example, if the printed component has a long side and a short side, and the cutting direction is set to one side, when the printed component needs to be physically damaged, the cutting member moves in the direction of the short side of the printed component. This allows the printed component to be damaged with minimal travel, saving space.

[0096] Through embodiments of the present invention, a cutting member can be used to cut the printing component, thereby severing the electrical connection between the printing component and the imaging device. Once severed, the printing component cannot perform normal print head operation, resulting in visible and unacceptable print defects. Furthermore, the cutting member may also sever repairable components (such as flexible circuits and connectors), thereby increasing the difficulty and cost of repair.

[0097] In another possible example, the destruction structure 102 is movably provided, or is connected to a force-applying portion for moving the destruction structure 102 .

[0098] Exemplarily, the above-mentioned destructive structure 102 can move in multiple directions such as up, down, left, right, front, and back, or is connected to a force-applying portion 1021 for moving the above-mentioned destructive structure 102 to assist the destructive structure 102 in achieving multiple directions such as up, down, left, right, front, and back, thereby controlling the position, area, and degree of destruction of the printed component, thereby achieving a more anti-reuse effect.

[0099] For example, Figure 4Another destructive structure 102 shown also includes a force-applying portion 1021 that can move in directions such as up and down, left and right. After the consumable box 2 stops printing and returns to its original position, the force-applying portion 1021 will move to be close to the printing component 22 under the control of the main control module 11 and continue to apply stress. The printing component is damaged by the stress of the force-applying portion 1021. If the force-applying portion is a protrusion, a blade, etc., the printing component cannot be printed normally after being damaged.

[0100] In another possible example, the above-mentioned destruction structure 102 further includes:

[0101] The heating component is used to heat the printing component when destroying the printing component, so as to cause thermal damage to the printing component.

[0102] like Figure 5 As shown, the destructive structure 102 is provided with a heating unit 1022 such as a heating resistor or heating coil. The main control module 11 applies voltage or current to the heating unit 1022 to heat it up, thereby baking the printing element 22 at high temperature, causing it to suffer thermal damage or melt, resulting in irreversible damage and preventing normal printing. The heating unit 1022 can also be movable, allowing it to be brought closer to the printing element to cause thermal damage.

[0103] As an optional embodiment, when physical damage to printed components is required, the heating element heats up to a temperature that can damage the printed components, such as melting the rubber of the photosensitive drum or causing thermal damage to the circuitry in the print head or the print head, leading to failure. Furthermore, the heating element may also heat repairable components (such as flexible circuits and connectors), damaging them and increasing the difficulty and cost of repair.

[0104] In an embodiment of the present invention, a heating component can be used to heat the printing component to a temperature exceeding the normal operating temperature. More preferably, the temperature can destroy the physical or electrical characteristics of the printing component, causing it to be irreversibly damaged, thereby making it impossible to complete normal printing operations, thereby outputting visible and unacceptable printing defects.

[0105] In addition, the inability to print properly may be referred to in this manual as "unacceptable printing results" or "unacceptable printing results," which means that the printed text or image contains visually discernible printing defects. Such printing defects may include any one or more of the following: failure to print data, incorrect print data, missing print data, broken print data, streaked prints, ghosting print data, too light print data, or too dark print data.

[0106] Exemplarily, the main control module 11 is further configured to determine whether the consumables box has reached a specified discard condition, and when the specified discard condition is reached, control the destruction structure 102 to perform irreversible physical destruction on the printing component.

[0107] Optionally, in an embodiment of the present invention, the specified discard conditions are as specified in this specification, including any one or more of the following situations: exhaustion state, short circuit or break or open circuit, cracks, blockage, abnormal temperature, reaching the specified number of uses, and reaching the specified usage time.

[0108] Optional, still as Figure 3 As shown, the printing consumables chip may also include a memory 26, which is used to store the cartridge model, ink model, serial number, encryption and decryption program or data, manufacturer information, regional information, etc. It can also be used to store abnormal working electrical conditions. The imaging device 1 reads the abnormal working electrical conditions in the printing consumables chip and generates a trigger signal to trigger the main control module to control the destructive structure to perform irreversible physical damage to the printing components of the consumable box. In addition, it can also trigger the corresponding module of the imaging device 1 or the electrical condition control module of the printing consumables chip to apply abnormal working electrical conditions to the consumable circuit to cause it to cause irreversible damage.

[0109] This embodiment also provides a control circuit, including: a first interface module, the first interface module is used to electrically connect to the consumable circuit on the consumable box to realize data transmission; the main control module is electrically connected to the first interface module, the main control module is used to obtain data information of the consumable circuit through the first interface module, and when it is detected that the data information reaches a specified discard condition, abnormal normal electrical conditions are applied to cause irreversible damage to the printing components in the consumable circuit.

[0110] Exemplarily, the control circuit further includes a sensor processing module, which is used to obtain or compare detection data of the sensor, and the main control module obtains the specified discarding condition according to the detection data.

[0111] An embodiment of the present invention further provides an imaging device, including a mounting structure for accommodating a consumables box, and including any one of the above-mentioned control circuits.

[0112] Optionally, the above-mentioned electrical condition control module can be a voltage converter or a current source, etc., and when the trigger condition is reached, it can also output abnormal working electrical conditions that are sufficient to cause irreversible damage to the printing circuit, causing irreversible damage to the printing components in the consumable circuit.

[0113] Optionally, the abnormal operating electrical condition is such that the printing component exceeds its normal operating tolerance value. The abnormal operating electrical condition is applied to the printing component that is directly electrically coupled to the first interface module.

[0114] In one example, the abnormal operating electrical condition is applied to a printing component that is directly electrically coupled to the first interface module 10 of the image forming device 1 .

[0115] The print head is also provided with a first interface module, which is electrically connected to the second interface module of the flexible circuit (the combined interface module is generally sealed and packaged to prevent the interface module and nearby circuits from being corroded or damaged. The combination method is generally direct connection, laser welding, wire binding, etc.). The second interface module of the flexible circuit is provided with a contact module, and the contact module is connected to the second interface module via a wire trace, so that the signal of the main control circuit is transmitted to the print head chip through the second interface module and the first interface module, and the data of the print head chip is transmitted to the main control circuit through the first interface module and the second interface module. The flexible circuit is attached to the outside of the consumable box housing and is used to realize signal transmission between the main control device and the print head chip. For a laser printer, the printing component can be the photosensitive component of the photosensitive drum.

[0116] The printing component can be any element, module or port element involved in the printing process, or a combination of any number of elements, modules or ports involved in the printing process. When these printing components are irreversibly damaged, even if the consumable box 2 passes the certification of the imaging device 1, the printing effect will be greatly reduced or even unable to print, and then it cannot be put into market use. Therefore, it completely solves the problem of an untrustworthy third party putting the repaired consumable box 2 into market use.

[0117] An embodiment of the present invention also provides a chip, for example, a printing consumables chip in the consumables box 2, including: a second interface module, used to electrically connect to the first interface module of the imaging device to realize data transmission; a printing component, the above-mentioned printing component is used to receive the control signal sent from the above-mentioned second interface module and perform printing action; the above-mentioned electrical condition control module is used to receive the trigger signal sent from the above-mentioned second interface module, and generate abnormal working electrical conditions that cause irreversible damage to the above-mentioned printing component according to the above-mentioned trigger signal.

[0118] In addition, the printing consumable chip itself has a microcontroller that can determine whether the consumable chip has reached a specified discard condition. When the specified discard condition is reached, the printing component of the consumable chip is irreversibly damaged. The consumable chip includes a sensor processing module, a memory, a second statistical module, etc. The sensor processing module is used to process sensor detection results, the memory is used to store the specified discard condition, and the statistical module is used to calculate the consumable parameters or electrical parameter results. The microcontroller determines whether the printing consumable or consumable chip has reached the specified discard condition based on the sensor processing module, the memory data, and the results of the second statistical module. If so, the printing component of the consumable circuit is irreversibly damaged.

[0119] At this time, the consumable chip can also include an electrical condition control module. When the microcontroller determines that the printing consumables or consumable chip are in a specified discard condition, a trigger signal is applied to the electrical condition control module. The electrical condition control module generates an abnormal working electrical condition that causes irreversible damage to the above-mentioned printing components based on the trigger signal.

[0120] In an optional embodiment, the consumable level sensor 251 may be set on the inner wall of the consumable box 2, and be set vertically from top to bottom. The imaging device 1 reads the thermal data, resistance data, voltage data, etc. of the sensor to determine the remaining amount of consumables at this time. When a certain value is reached, it is determined that the consumables are exhausted.

[0121] For example, the sensor at the top of the box body has a slower heat transfer rate and a higher temperature because it is not covered by ink, while the sensor at the bottom of the box body has a faster heat transfer rate and a lower temperature because it is covered by ink. The ink level is determined by temperature to determine whether the consumables are present or exhausted. Alternatively, the consumable level sensor 251 is integrated into the printing component 22 to determine the remaining amount of consumables by whether bubbles are generated and the time of bubble generation. When a certain value is reached (such as a resistance, voltage, or capacitance value greater than or less than a certain value), the consumables are determined to be exhausted. Alternatively, the consumable level sensor 251 is not provided, and the consumable box 2 uses the second statistical module 28 to count the consumable consumption and determine whether the consumables are exhausted (such as counting the amount of ink used for each print and then comparing it with the total ink amount data read from the consumable circuit to obtain an estimated result). When the exhaustion level or exhaustion state is reached, it is considered that the specified discard condition has been met.

[0122] In addition, the second statistical module 28 can also count the number of failures that occur in the consumable cartridge 2 during the printing process, such as the number of activation failures, the number of temperature anomalies, the number of bubble anomalies, etc. When a predetermined value is reached, it is also considered that the specified rejection condition has been met. The second statistical module 28 is used to count whether the consumable parameters (such as consumable levels) or electrical parameters (such as the number of activation failures, the number of temperature anomalies, the number of bubble anomalies, etc.) have reached a specified threshold level. The statistical results are stored in the memory 26 of the consumable cartridge, and the statistical results serve as the specified rejection condition.

[0123] Still Figure 3 As shown, a temperature sensor 252 can also be provided in the box body of the consumable box 2 to detect the temperature of the printing component 22, a certain printing area, the ink temperature, etc. The activation energy applied to the printing component 22 can be changed according to the signal detected by the temperature sensor 252 (such as a sampled analog signal, which can also be converted into a data signal for processing, etc.), and the energy of the heating circuit of different printing areas can be adjusted to balance the temperature of each area. When the imaging device 1 detects that the temperature of a certain temperature detection sensor is always lower than a certain value or higher than a certain value, the corresponding circuit may be broken or disconnected, and it is considered that the specified discard condition has been met.

[0124] For example, Figure 3 As shown, a crack sensor 253 may also be provided within the body of the consumables box 2. For example, if an inkjet print head is provided in the imaging device 1, the heating resistor serves as the printing component 22. A continuous coil of conductive wire (such as a metal wire, polysilicon wire, etc.) may be provided around the heating resistor as the crack sensor 253. When the crack sensor 253 is detected as broken or open, it indicates that a fracture has occurred around the heating resistor. Furthermore, crack sensors 253 may be provided around a main control module 11, around a chip, or in other locations to detect the presence of cracks. The presence of a crack indicates that a component or circuit has been or is about to be damaged, and a specified discard condition is considered to have occurred.

[0125] In another example, Figure 3As shown, a bubble sensor 254 can also be provided in the box body of the consumable box 2. When the amount of ink is sufficient or the corresponding flow path, hole or groove of the heating resistor is not blocked, bubbles are generated at a specified time and disappear at a specified time. For example, the bubble sensor 254 is like a conductor and is provided around the printing component 22. Initially, the ejection chamber on the print head is filled with ink, and the bubble sensor 254 is covered by ink. The ink, as a conductor, can communicate with the grounding component or other components, so that the bubble sensor 254 is detected to have a small resistance, a small voltage, a small capacitance, etc. When the bubble nucleus gradually forms a bubble covering the bubble sensor 254, the bubble sensor 254 has no conductive effect of the ink. At this time, the detected data has a large resistance, a large voltage, a large capacitance, etc., and then the bubble will continue to grow and eject the ink from the inkjet hole. When the activation of the printing component 22 is stopped, due to the effect of negative pressure, the ink will continue to fill the ejection chamber, so that the bubble sensor 254 is covered by ink again, resulting in a small resistance, a small voltage, a small capacitance, etc. (of course, other parameters or the opposite of the above parameters may also be the result).

[0126] As an optional implementation, if bubbles fail to appear or disappear within a specified timeframe, it could be that the inkjet orifice or ink flow path is clogged, preventing normal inkjet ejection, or performance is degraded. Alternatively, the time between bubble generation and ink coverage in the bubble sensor can be used to determine the ink level and the presence or level of consumables, as well as whether the consumables are depleted. When sensor data indicates printhead clogs, performance degradation, or consumable levels reaching a specified value, a designated discard condition is considered to have occurred.

[0127] It should be noted that, from an environmental protection perspective, the embodiment of the present invention allows the consumable box 2 to be repaired and reused when the consumable box 2 and the consumable circuit or printing component have not reached the scrap standard. When the number of times the consumable box 2 or the consumable circuit is used reaches a specified value or the usage time exceeds a certain value, the printing performance may be greatly reduced. Therefore, when the number of uses or the usage time is greater than the specified value, it is also considered that the specified discard conditions have been met, and in this case, the repaired consumable box 2 is not allowed to continue to be used. The number of uses reaching a specified value and the usage time exceeding a certain value may be to detect the performance of any of the above-mentioned sensors (such as consumable level sensors, temperature sensors, crack sensors, bubble sensors, etc.). If the detection result is abnormal, there is a risk that the device cannot accurately measure the results. These problems can be considered to have reached the specified discard conditions.

[0128] Any of the above-mentioned exhaustion, short circuit or open circuit, abnormal temperature, cracking, blockage, reaching the specified number of uses, reaching the specified usage time, etc., are conditions for the consumable box, consumable circuit or printing component to reach the specified disposal. The specified disposal condition can be any one condition or a combination of multiple conditions. This does not exhaust all possible specified disposal conditions, but does not exclude other possible or future specified disposal conditions.

[0129] For example, Figure 6 As shown, the main control end of the imaging device 1, that is, the control circuit, includes a main control module 11 (or called a main controller or control module, etc.), which is used to realize printing signal processing, data transmission, signal detection, storage, data reading and writing, etc. It can also include various modules for realizing the above-mentioned judgment of specified discard conditions and working modules for generating abnormal normal electrical conditions. For example, it also has a second electrical condition control module 15. When the main control module 11 obtains the specified discard condition, it provides a trigger signal to the second electrical condition control module 15. The second electrical condition control module 15 will generate abnormal normal electrical conditions when the signal appears, so that the printing component will produce irreversible destructive electrical conditions.

[0130] The embodiment of the present invention further provides a consumables box, comprising any one of the above chips. Figure 3 The printing consumable chip within the consumable cartridge 2 may also include a first electrical condition control module 27. The printing consumable chip includes a consumable circuit. As mentioned above, the consumable circuit is used to receive control signals from the imaging device 1 and perform printing operations. When circuit functions such as sensors and the sensor processing module 14 are absent, the printing consumable chip may only protect the printing components used to perform printing operations. Furthermore, when the first electrical condition control module 27 receives a trigger signal from the first interface module 10 of the imaging device 1, it can generate an electrical condition that irreversibly damages the printing components and causes abnormal operation based on the trigger signal. Of course, the first electrical condition control module 27 may also be a functional circuit within the consumable circuit, rather than a separate module.

[0131] like Figure 6 As shown, there is also a computer storage medium 16 in the imaging device 1, which can be used to store control logic for running printing actions, sensor data comparison logic and other logics, and can also store the program and logic of the implementation method mentioned above.

[0132] In addition, the above-mentioned arbitrary specified discarding conditions can be, for example, Figure 6In the schematic diagram of the imaging device shown, the imaging device 1 activates various sensors and a sensor processing module 14 to obtain detection data. The detection data is then compared with a specified result preset in a computer storage medium 16. If the detection data exceeds the specified result, a specified rejection condition is considered to have occurred. Alternatively, the consumable circuit stores the measurement results in its own memory (such as memory 26). The imaging device 1 reads the measurement results through the data reading module 12 and the first statistical module 13, performs statistical analysis, and compares the results to determine whether the specified rejection condition has occurred.

[0133] Of course, the consumable circuit may also generate specified discard condition data after comparison based on the measurement results. The specified discard condition data is stored in the memory 26. When the imaging device 1 reads the specified discard condition data through the data reading module 12, it is also considered that the specified discard condition has been generated.

[0134] An example is Figure 7 As shown, it may include a data receiving module 51, a decoder 52, a register 53, a latch 54, an address generator 55, various arithmetic logic gates 56, a switch controller 57, etc. Each printing component 22 is connected to the corresponding switch controller 57. The data receiving module 51 receives the address signal and the print data signal and decodes them through the decoder 52 and transmits them to the corresponding module. The register 53 and the latch 54 latch the print data under the control of the clock control signal. The address generator 55 receives the address signal and decodes it to generate the selected address of the corresponding printing component 22. The switch controller 57 is jointly controlled by the selected address and the print data and is selected. When an excitation signal is applied to the excitation line 59 of the printing component 22 and the switch controller 57 is turned on, the printing component 22 is excited to eject the ink out of the ejection hole.

[0135] Another example is Figure 8 As shown, it may include a data receiving module 51, a decoder 52, a register 53, a latch 54, an address generator 55, various operation logic gates 56, a switch controller 57, a printing component 22, etc. Figure 7 The difference is that the address generator 55 has an address data receiving port for obtaining an address signal from the imaging device 1 .

[0136] Another example is Figure 9 As shown, it may include a data receiving module 51, a decoder 52, a register 53, a latch 54, an address generator 55, a switch controller 57, a printing component 22, etc. Figure 5 and Figure 6The difference between the example is that it also includes a pre-charging circuit 61 and a selection circuit 62. The pre-charging circuit 61 can receive a pre-charging signal sent from the pre-charging line 64, and the selection circuit 62 can receive a selection signal sent from the selection line 63. The pre-charging circuit 61 charges the control end of the switch controller 57 to a level that can be turned on. The selection circuit 62 receives the address signal, the print data signal, and the selection signal on the selection line 63 to control whether the control end of the pre-charged switch controller 57 is discharged or charged. When the low level is valid, the selection circuit 62 receives a valid address signal and print data signal, and the control end maintains the conduction circuit. At this time, if the excitation line 59 is applied with an excitation signal, the printing component 22 is excited to eject ink out of the ejection hole. If any one of the address signal or print data of the selection circuit 62 is high, the selection signal on the selection line 63 is valid, and the control end of the switch controller 57 is discharged. At this time, even if there is an excitation signal, the printing component cannot print normally.

[0137] The above examples merely illustrate the circuit structure of the printing component. A variety of other circuit structures and connection methods exist for these components. Of course, other modules, such as boost modules, also participate in controlling the printing component 22. These circuits, which enable the printing component 22 to print normally, constitute the printing component. These circuit modules have specified electrical operating conditions. For example, the excitation voltage of the printing component 22 (e.g., the heating resistor) is 32V or 1mA, the drive voltage of the switch controller (e.g., NMOS) is 5V, and the operating voltage of the arithmetic logic gate is 3.3V. When these circuit modules exceed these specified electrical operating conditions and reach their upper tolerance limits, they can suffer irreversible damage. For example, semiconductor devices such as NMOS, PMOS, and CMOS can be damaged beyond repair and continued use after thermal breakdown. Heating resistors, made of metal wire or polysilicon, can melt or thermally break down when exceeding specified voltages or currents, also resulting in irreversible damage and irreversible use. Electrical operating conditions can include voltage, current, power, and other electrical parameters.

[0138] The units, circuits, and other components of the printing unit 22 and main control module 11 that enable the consumable cartridge 2 to perform normal printing operations are collectively referred to as the printing unit. Because data stored in the memory may not affect the normal printing operation of the printing unit 22, only those modules that participate in the printing process and are essential for printing text or images are considered printing units. If the data in the memory 26 is essential for printing, it also belongs to the printing unit. If the data in the memory 26 can be modified and replaced without affecting printing, it does not belong to the printing unit.

[0139] Modules such as sensors and sensor processing modules that are essential to the printing process and cannot be replaced or repaired later are also considered printing components. If these components are irreversibly damaged, the entire printing system must be replaced to achieve acceptable printing results. Alternatively, these damaged components can be repaired or replaced, but the high cost of such repairs and replacements makes it uneconomical for untrustworthy third parties to repair or replace damaged consumable cartridges.

[0140] If any of the printing components suffers irreversible damage, the printing component 22 will be unable to complete the printing operation normally. Normal printing operation means that acceptable printing results can be obtained on the print medium. If the printing component 22 is damaged, it cannot be activated even if it receives the correct signal; if the address generator is damaged, it cannot generate the correct address or generates an incorrect address, resulting in incorrect print data or failure to print; if the data receiving module is damaged, data cannot be received and transmitted normally, and normal printing cannot be performed; if the latch or register is damaged, data cannot be stored correctly, resulting in printing errors or failure to print; if various logic gates or switch controllers are damaged, the printing component 22 is in an open circuit state and cannot receive the activation signal, etc.

[0141] Of course, damage to various components or modules can also produce other unacceptable printing results or effects. If these printing components are irreversibly damaged, or if the damage reaches a certain level, the result is that normal printing cannot be completed, resulting in unacceptable printing effects or unacceptable printing effects, that is, the printed text or images contain printing defects that can be seen by the naked eye.

[0142] Therefore, the destruction structure is controlled by the main control module to irreversibly physically destroy the printing component of the consumable cartridge. The printing component can be any component, module, or port component involved in the printing process, or a combination of any number of components, modules, or ports involved in the printing process.

[0143] For example, Figure 7As shown, one end of the printing component 22 is connected to a power supply terminal for receiving an activation signal (e.g., FIRE, firing line 59), and the other end is electrically connected to a switch controller 57. When the switch controller 57 is turned on and the printing component 22 receives the activation signal, it can print, that is, eject or transfer the consumable material onto the print medium 3, such as the heating resistor in the print head 21 ejecting the ink in the ejection chamber from the ejection hole. When the switch controller 57 is turned on, the end of the printing component 22 that receives the activation signal outputs an abnormal normal operating electrical condition, causing electrical or physical damage to the printing component 22, resulting in irreversible damage and making it impossible to complete normal printing.

[0144] For example, Figure 8 As shown, one end of the switch controller 57 is electrically connected to the printing component 22 and the other end is connected to the power supply. When the power supply receives a conduction signal, the switch controller 57 is turned on and transmits an activation signal to the printing component 22. When the printing component 22 receives the activation signal, it can print, that is, eject or transfer the consumable material onto the printing medium 3. The control switch is, for example, a PMOS device (high-side switch), with its source connected to a high level and its drain connected to the printing component 22, and turned on when the gate receives a low level; or an NMOS device (low-side switch), with its power supply connected to one end of the printing component 22 and the drain of the other end of the printing component 22, with its source connected to a low level, and turned on when the gate receives a high level. When abnormal normal operating electrical conditions are applied to the source, drain, or gate of the switch controller (such as a PMOS or NMOS), the switch controller may suffer thermal breakdown, resulting in damage, and thus irreversible damage, causing failure to print normally.

[0145] If the switch controller is not directly connected to a connection point on the second interface module 20, but is instead connected between the printing component 22 and ground, and is switched on and off by the signal output by the arithmetic logic gate, then the switch controller does not constitute a printing component that has a direct electrical connection with the second interface module 20 or the first interface module 10. Similarly, if the printing component 22 utilizes a high-side switch, i.e., is not directly connected to a power supply terminal (e.g., excitation line 59), then the printing component 22 does not constitute a printing component that has a direct electrical connection with the second interface module 20 or the first interface module 10. Since the consumable circuit on the consumable cartridge 2 transmits data with the first interface module 10 of the imaging device 1 via the second interface module 20, the first interface module 10 and the second interface module 20 have a direct electrical connection, and the second interface module 20 is connected to the consumable circuit. Therefore, a printing component that has a direct electrical coupling with the first interface module 10 is a printing component that has a direct electrical connection with the second interface module 20. This type of control is simpler and can control all existing consumable boxes 2 on the market, those that have been produced and are waiting to be sold, those that have been discarded and repaired, etc., without any processing of the consumable boxes. It is more versatile and the anti-reuse measures cover a wider range.

[0146] For example, Figure 9 As shown, the address generator 55 does not directly receive the address signal sent by the data receiving module 51. Instead, its input terminal directly receives the address signal sent by the imaging device 1 and selects the corresponding printing component 22 through decoding. When the imaging device 1 sends abnormal operating conditions to the address generator through the address line on the first interface module 10, the corresponding interface or internal components of the address generator are damaged, causing irreversible damage, resulting in the inability to properly receive the address signal or complete decoding. As a result, the printing component 22 that should be selected for printing cannot be selected, and thus normal printing cannot be completed.

[0147] As long as the printing components have a direct electrical connection with the second interface module 20, they are all printing components that can have a direct electrical coupling with the first interface module 10 and can be directly controlled by the control signal sent by the imaging device 1. These modules can also be input ports of any signal, such as a clock terminal, a selection terminal (or a selection circuit), a pre-charging terminal (or a pre-charging circuit), etc. By inputting abnormal normal operating electrical conditions at any one or more combined ports, the corresponding port devices are damaged, resulting in irreversible damage, which makes it impossible to complete normal printing work.

[0148] It should be noted that the first interface module 10 and the second interface module 20 (collectively referred to as interface modules) can adopt a variety of protocols, such as I2C protocol, CAN bus protocol, SPI protocol, custom protocol, etc. In addition, the interface module can also include multiple interface terminals (or contacts), such as power terminal, ground terminal, clock terminal, print data transmission terminal, latch signal terminal, address signal terminal, activation signal terminal, selection signal terminal, pre-charge signal terminal, sensor terminal, data write and read terminal, etc. The imaging device end and the consumable box end are both provided with corresponding interfaces, so that the two can complete communication operations such as printing control and data reading and writing.

[0149] Each type of interface can be one or more, such as one or more ground terminals, one or more print data transmission terminals, and one or more address signal terminals. When there is only one print data transmission terminal or address signal terminal, time division multiplexing and other methods can be used for signal transmission. The connection between the imaging device end and the consumable box end can be a direct contact-to-contact connection, a wired connection, or a wireless connection. Here, the connection between the imaging device end and the consumable box end is collectively referred to as a connection through a control line. The control line includes functional lines for realizing data transmission between corresponding ports, such as power lines, ground lines, clock lines, latch lines, address lines, activation lines, selection lines, pre-charge lines, sensor control lines, etc. When these lines are not directly connected to the second interface module 20, they become internal functional lines, and those that have a direct connection relationship with the second interface module 20 are external control lines.

[0150] For example, in the attached Figure 7 、 8 In Figures 9 and 9, the suspended control lines are directly electrically connected to the second interface module 20 and are used to directly receive control signals from the imaging device 1. The non-suspended lines are not directly electrically connected to the second interface module 20 and are therefore internal functional lines. Therefore, the printing components that are directly electrically connected to the second interface module 20 and directly electrically coupled to the first interface module 10 are modules that are directly electrically connected to these external control lines.

[0151] In one example, in another implementation described in the above example, the abnormal operating electrical condition is applied to a printing component that has a direct electrical coupling relationship with the first interface module at the imaging device 1 .

[0152] like Figure 10As shown, the main control end of the imaging device 1 is provided with a first interface module 10, which is used to electrically connect to the consumable circuit (when only the printing component is provided, the printing component is also the consumable circuit) at the consumable cartridge end to achieve data transmission. Similarly, the consumable circuit is also provided with a second interface module 20, which is used to electrically connect to the first interface module 10 of the imaging device 1 to achieve data transmission. The first interface module 10 and the second interface module 20 can be connected in various ways, such as direct connection, wired connection, or wireless connection. For example, the data receiving module receives print data (DATA), clock data (CLK), address data (ADDRESS), etc. After receiving this data, it transmits it to the corresponding receiving unit (such as a latch, register, address generator, arithmetic logic gate, etc.). The data received by these receiving units is controlled by the data receiving module. After receiving the data, the data receiving module outputs a corresponding level signal (such as a logic high "1" such as 3.3-5V; a logic low "0" such as below 1.5V or 0V, etc.) to enable the corresponding receiving unit to operate (register data, latch data, generate address signals, turn on or off, etc.).

[0153] In the above situation, it is difficult for imaging device 1 to directly control the electrical conditions of the receiving units because the inputs of these receiving elements are controlled by the data receiving module. Generally speaking, existing data receiving modules do not have the ability to output signals that put the receiving elements into abnormal operating electrical conditions after receiving data, unless the data receiving module itself receives the trigger conditions of imaging device 1 and, under the action of these trigger conditions, outputs an operating module that puts the receiving units into abnormal operating conditions. If imaging device 1 applies abnormal operating electrical conditions to the data receiving module, the corresponding module of the data receiving module will be damaged, making it impossible to properly transmit data to subsequent receiving units. It may also be impossible for the imaging device 1 to properly receive data, resulting in the inability to complete normal printing.

[0154] The present invention provides a control method for an imaging device, which is applied to any one of the above-mentioned imaging devices, wherein the above-mentioned imaging device includes a main body and a main control module connected thereto; Figure 11 FIG. 1 is a flow chart of a control method for an imaging device provided by an embodiment of the present invention. Figure 11 As shown, the method includes:

[0155] S101, the main control module detects whether the consumables box built into the main body of the imaging device has reached a specified discard condition;

[0156] S102: When the consumables box reaches the specified discarding condition, the main control module controls the built-in destruction structure of the main body to irreversibly destroy the printing components in the consumables box, so that the printing components have printing defects.

[0157] Optionally, the imaging device can accommodate one or more consumable boxes, which are provided with printing components (for example, a print head, a photosensitive drum, etc.), and a destruction structure is provided in the imaging device. Optionally, in an embodiment of the present invention, the destruction structure can be in the form of a physical stress applying component to achieve irreversible damage to the printing components.

[0158] In one possible example, as shown in the figure, the consumable box has a box body, a printing component, and the box body is used to hold consumable materials (such as ink, toner, etc., and when it is a photosensitive drum, it is used to hold a photosensitive drum unit or can also hold waste toner). The consumable material can be sprayed or transferred to a printing medium (such as paper, plastic, cloth, etc.) under the action of the printing component to form the required text or image.

[0159] In another possible example, the consumables cartridge may also be equipped with various types of sensors and corresponding sensor detection circuits, such as a consumables level sensor, a temperature sensor, a crack sensor, and an air bubble sensor. These sensors may be integrated into the printing component and print control module chip, or they may be independent modules, forming another independent chip or circuit. Herein, these circuits on the printing consumables side, such as the printing component, print control module, sensors, and sensor detection circuits, are collectively referred to as consumable circuits.

[0160] In addition, these consumable circuits can be independent or integrated. When the consumable box does not have various functional modules such as sensors and sensor detection circuits, and only has printing components and printing control modules for completing printing actions, the printing components and printing control modules can be considered as consumable circuits.

[0161] Optionally, the main control module is used to obtain data information of the consumable circuit, and when it is detected that the data information reaches a specified discard condition, it controls the destruction structure to irreversibly destroy the printing component, so that the printing component has a printing defect.

[0162] Optionally, the abnormal normal operating electrical condition is to cause the above-mentioned printing component to exceed its normal operating tolerance value; the above-mentioned abnormal normal operating electrical condition is applied to the above-mentioned printing component that has a direct electrical coupling relationship with the first interface module.

[0163] In a possible example, the above-mentioned specified discarding conditions include any one or more of the following situations: exhaustion state, short circuit or disconnection or open circuit, cracks, blockage, abnormal temperature, reaching the specified number of uses, and reaching the specified usage time.

[0164] In another possible example, the printing defects include any one or more of the following: failure to print data, incorrect print data, missing print data, broken print data, streaks in printing, ghosting of print data, too light print data, or too dark print data.

[0165] For example, when a printhead reaches a specified discard condition, the main control module controls the destructive structure to apply physical stress to the printhead components. The degree of physical stress applied should be sufficient to cause irreversible physical damage to the printhead components, resulting in visible defects. When the printhead components are irreversibly damaged, even recycled consumables cannot be simply replaced and reproduced through external structural means, communication authentication, or other methods. This effectively prevents the continued use of unauthorized repaired consumables. Furthermore, it prevents consumables that have reached the discard standard from being used again after repair, thereby harming customer interests.

[0166] It is understandable that when these printing components are irreversibly damaged, even if the consumable box has passed the certification of the imaging device, the printing effect will be greatly reduced or even unable to print, so it cannot continue to be put into market use. Therefore, it completely solves the problem of untrustworthy third parties continuing to put repaired consumable boxes into the market, effectively preventing damage to imaging equipment, reduction in printing quality, and damage to customer interests.

[0167] Exemplarily, the irreversible damage to the printing component can be partial or complete. For example, the entire printing component is burned, resulting in all nozzles being unable to spray ink; or it can be partial printing component burning, such as burning a certain area (such as the middle, a certain column, the left side, the right side, or a combination) of the printing component. In this way, even if some nozzles can spray ink normally, the damaged area cannot spray ink normally, resulting in unacceptable printing effects for customers, thereby preventing the repaired consumables from being put on the market. For example, it can also be that the entire circuit structure or partial circuit structure of one or more of the data receiving module, latch, register, address generator, various arithmetic logic gates, switch control, pre-charge circuit, selection circuit, etc. is damaged, resulting in the inability to complete the printing work normally, resulting in unacceptable printing effects for customers. The irreversible damage to the printing component can be caused by a short circuit, a break, an open circuit, the inability to receive data, the inability to output data, the output data error, the non-response to signals, etc. Unacceptable printing effects include the inability to print data, incorrect print data, missing print data, broken print data, stripes on the print, ghosting of print data, too light print data, too dark print data, etc. Unacceptable printing effects are obvious defects visible to the naked eye. For ordinary customers or consumers, such visible printing effects are unacceptable.

[0168] In an optional example, at S201, the consumable box is loaded into the imaging device. At this time, the second interface module 20 on the consumable box is electrically connected to the first interface module 10 on the imaging device to facilitate communication between the two. At S202, the imaging device uses the consumable box to perform printing, spraying or transferring consumable materials such as ink and toner onto the printing medium to form text or images. Before S202, communication authentication between the imaging device and the consumable box can also be performed, such as reading the serial number, encryption and decryption authentication, etc. Only the consumable box that passes the authentication is allowed to perform further printing actions. At S203, the imaging device stops printing. Preferably, the stop printing action can be: printing is stopped only after the current print job is processed, especially for consumable boxes that are about to reach the scrap standard but are barely usable and will not be stopped until the user's current job is completed. Perform step S204, otherwise it will cause damage to the user. When certain conditions do not allow continued printing to complete the current job, printing can also be stopped immediately; at S204, a prompt or alarm is issued to the user, such as a reminder of consumable box damage and a printing defect reminder. At S205, if printing is continued, printing defects that can be identified by the naked eye are output, such as inability to print data, incorrect print data, missing print data, broken print data, stripes on the print, ghosting of print data, too light color of print data, too dark color of print data, etc. Unacceptable printing effects are obvious defects visible to the naked eye; at S206, by detecting the printing components of the consumable box, it is determined that the printing components of the consumable box are irreversibly damaged, such as a short circuit, a break, an open circuit, inability to receive data, inability to output data, incorrect output data, no response to signals, etc.

[0169] It should be noted that there is no requirement for the order of steps S203-S206. A prompt or alarm may be issued first and then printing may be stopped, or printing may be stopped after a printing defect that can be identified by the naked eye occurs, and it is impossible that the printing component is damaged before the printing defect occurs; after the consumable box is removed from the imaging device, it can be found through inspection that the printing component has suffered irreversible damage.

[0170] The processing method of the present invention avoids the problems of external structure replacement and reproduction, and the potential for communication authentication to be cracked, thereby preventing the continued use of unauthorized repair consumables at the source. It also prevents consumables that have reached scrap standards from being used after repair, thereby harming customer interests.
