Description

Technical Field

[0001] The present application relates to the field of image forming technology, and in particular to a consumable chip and a consumable box. Background Art

[0002] Commonly used printers include: inkjet printers and laser printers. Inkjet printers use ink cartridges as consumable boxes to provide the printer with ink for printing, so as to form the text or pattern to be printed on the paper; laser printers use toner cartridges as consumable boxes to provide the printer with toner for printing, so as to form the text or pattern to be printed on the medium. The imaging principles and use of consumable boxes of copiers, fax machines and multi-function printers are basically the same as those of printers.

[0003] A consumable chip is generally installed on the shell of the consumable box. The data stored in the consumable chip includes the consumable model, consumable capacity, and consumable remaining quantity. When the consumable is exhausted, the user can replace the consumable with a new one and reset the consumable chip so that the data stored in the consumable chip is restored to the factory settings, so that the consumable chip can be reused. The existing consumable chip reset method is as follows: during use, when the consumable remaining quantity recorded in the consumable chip reaches the preset value, it does not respond to the next instruction sent by the printer. At this time, the printer will think that the consumable chip cannot be recognized and prompts to replace the ink cartridge. At this time, the user can unplug and plug the ink cartridge. During the first power-on process after the ink cartridge is unplugged, the chip will use the time between the first power-on and the printer sending the first instruction to perform a reset action and restore the ink volume related data. However, the above reset action will be affected by the length of time between the first power-on and the printer sending the first instruction. As the printer is updated, this time length becomes shorter and shorter, and the failure rate of the existing reset method is also getting higher and higher, affecting the normal use of the printer. Summary of the Invention

[0004] In view of this, the present application provides a consumable chip and a consumable box to help solve the problem of high reset failure rate caused by long reset time in the prior art.

[0005] In a first aspect, an embodiment of the present application provides a consumable chip, wherein the consumable chip is installed in a consumable box, and the consumable box is installed in an image forming device. The consumable chip stores consumable data and multiple copies of consumable backup data, each copy of the consumable backup data corresponding to a portion of the data attributes of the consumable data;

[0006] During a power cycle process of the power line between the image forming device and the consumable chip, a reset operation is performed multiple times to update the consumable backup data to the consumable data.

[0007] In an optional embodiment, the consumables data includes: consumables remaining data;

[0008] The one or more pieces of consumable backup data in the consumable backup storage area are backup data corresponding to the consumable remaining data.

[0009] In an optional embodiment, the resetting operation is performed multiple times in the power line circulation between the image forming device and the consumable chip.

[0010] When the consumable data meets the resetting condition, the resetting operation is performed multiple times in the power line circulation between the image forming device and the consumable chip.

[0011] In an optional embodiment, after each power-on of the power line, part of the consumable data is updated by at least one piece of consumable backup data.

[0012] In the single power-on process of the power line, part of the consumable data is updated by target consumable backup data corresponding to the attribute.

[0013] The target consumable backup data is consumable backup data associated with the current power-on.

[0014] In an optional embodiment, when the resetting operation performed in the current power-on is completed, the corresponding identification information is modified to be completed.

[0015] In an optional embodiment, when the resetting operation performed in the last power-on is completed, the target consumable backup data is consumable backup data associated with the current power-on, and when the resetting operation performed in the last power-on is not completed, the target consumable backup data is consumable backup data associated with the last power-on.

[0016] The completion of the resetting operation performed in each power-on is determined by the corresponding identification information.

[0017] In an optional embodiment, the number of pieces of consumable backup data is less than or equal to the number of the circulation power-on and power-off processes.

[0018] In an optional embodiment, the chip is provided with a resetting flag bit, and whether the consumable data meets the resetting condition is determined by the value of the resetting flag bit.

[0019] In an optional embodiment, the consumable data includes a consumable remaining value.

[0020] In the normal working process, when the consumable remaining value is lower than a consumable threshold value and the number of resetting operations previously performed by the consumable chip is less than a preset resetting number threshold value, the resetting flag bit is modified to a first value.

[0021] The first value is used to indicate that the consumable data meets a reset condition when the cycle power-on and power-off process is performed once under the power line.

[0022] In a second aspect, the embodiments of the present application provide a consumable cartridge, wherein the consumable cartridge is installed with the consumable chip provided in the first aspect.

[0023] In the embodiments of the present application, the consumable chip comprises a consumable data storage area and a consumable backup storage area, the consumable data storage area stores consumable data, and the consumable backup storage area stores a plurality of consumable backup data, each of which corresponds to part of the consumable data; when the consumable data meets a reset condition, a reset operation is performed multiple times in a cycle power-on and power-off process of the image forming device, so as to update the consumable backup data to the consumable data. In the embodiments of the present application, in the process of multiple power-on and power-off, only part of the consumable data is reset each time the power is turned on, and after multiple operations, the consumable data can be completely reset, thereby improving the success rate of the reset.

[0032] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0033] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0035] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0036] Common image forming devices usually have a detachable consumable cartridge inside which contains consumables (such as ink, toner, etc.) and on the shell of which a consumable chip for recording consumable data is installed. Referring to Figure 1 , the image forming device can include an image forming device and a consumable cartridge. The image forming device is used to perform image forming related operations to output a printed image. The consumable cartridge is a replaceable accessory in the image forming device. For example, when the image forming device is an inkjet printer, a laser printer, a 3D printer, a label printer, a needle printer, etc., the corresponding consumable cartridge is an ink cartridge, a toner cartridge, a selenium drum, a powder cartridge, a ribbon cartridge, etc.

[0037] In an implementable embodiment, the consumable cartridge can be a developing cartridge, which includes a developer accommodating portion and a developer conveying element. The developer accommodating portion is used to accommodate a developer such as toner, and the developer conveying element is a component for stirring and / or conveying toner, such as a powder feeding roller, a powder feeding screw, etc. The developing cartridge can also only include the developer accommodating portion or the developer conveying element, which is not limited here.

[0038] The consumable chip is an electronic device with a storage function, which can be installed in a consumable box, and the consumable box can be installed in an image forming device. When the consumable box is installed on the image forming device, the consumable chip is connected to the image forming device in a communication manner. The communication connection can be a communication connection through contacts, antennas or coils, and the embodiments of the present application are not limited to this. It should be noted that the consumable chip stores information including raw data, and the raw data is information related to the image forming device. For example, the raw data can include at least one of the following categories: (1) imaging control related parameters, such as: print engine control parameter information, specifically high voltage control parameters, fixing temperature parameters, paper feed speed control parameters, etc. When the image forming device is a color printer, it also includes color calibration parameter information or calibration patterns; (2) consumable related parameters, such as: various proportional factors for calculating toner consumption; or basic attribute information of consumables, wherein the basic attribute information of consumables can specifically be information such as consumable model, consumable serial number, consumable capacity and life. It should be noted that those skilled in the art can also design the consumable chip to store other types of raw data according to actual needs, and the embodiments of the present application are not limited to this.

[0039] Figure 2 This is a schematic diagram of the structure of an image forming device provided in an embodiment of the present application. Figure 2 As shown, the image forming device may include: a developer accommodating portion 11, a developing component 12, a developer conveying element 13, a photosensitive component 14, a transfer component 15 and a fixing assembly 5, etc. The paper to be printed moves in the paper feeding direction, and after successively undergoing the powder feeding operation of the developer conveying element 13 and the developing operation of the developing component 12, arrives at the clamping area between the photosensitive component 14 and the transfer component 15 for transfer, and then passes through the fixing assembly 5 for fixing to complete the image forming operation, wherein the developer accommodating portion 11 is used to accommodate the developer, which can be materials such as toner and carbon powder; the developing component 12 includes: a developing roller, etc.; the developer conveying element 13 includes: a powder feeding roller, etc.; the photosensitive component 14 includes: a photosensitive drum (OPC, Organic Photo Conductor) and a charging roller, etc., wherein the charging roller is used to charge the photosensitive drum.

[0040] Typically, an image forming device is detachably mounted with at least one consumable material. Figure 2 As an example of the image forming device shown in FIG, the image forming device is detachably mounted with four consumables (respectively Figure 2 The consumables 1, 2, 3 and 4 shown are used to provide the image forming device with four colors of developers (black K, cyan C, magenta M and yellow Y), respectively. Of course, in other embodiments, the number of consumables installed in the image forming device can be increased or decreased, for example, to 5 or 6 or even more or less, etc., and this application does not limit this.

[0041] The consumable chip stores a consumable remaining value corresponding to the remaining amount of consumable in the consumable cartridge. When the consumable is used up (at which time the consumable remaining value is lower than a preset value), the image forming device can output a prompt information for replacing the consumable to remind the user to dismount the consumable cartridge and fill in new consumable. Optionally, the image forming device can output a first prompt information to prompt the user to replenish the consumable, and the specific way of outputting the first prompt information includes but is not limited to displaying or printing on the display panel of the image forming device. In some scenarios, the image forming device is communicatively connected with a user device such as a smart phone, and the first prompt information can also be sent to the user through the user device.

[0042] Specifically, for the image forming device to determine that the consumable chip corresponding remaining value is lower than the consumable threshold, in one embodiment, the image forming device acquires the remaining value stored in the consumable chip, and compares it with the consumable threshold to determine whether the remaining value of the consumable chip is lower than the consumable threshold. If the remaining value stored in the consumable chip is lower than the consumable threshold, the first prompt information is output. In another embodiment, the consumable chip pre-stores the consumable threshold. When the consumable chip determines that the remaining value stored by itself is lower than the consumable threshold, the second prompt information is output to the image forming device. The second prompt information is used for the consumable chip to inform the image forming device that the corresponding remaining value is lower than the consumable threshold. At this time, the image forming device can output the first prompt information based on the received second prompt information.

[0043] When the user replaces the consumable and re-installs the consumable cartridge into the image forming device, the image forming device supplies power to the consumable chip. After the power is supplied, the consumable chip performs a reset operation, so that the consumable data returns to the factory setting or approaches the factory setting, to realize repeated use. For example, the consumable data includes the usage information of the consumable, which can be the consumption amount or the remaining amount of the consumable. In the reset process, the consumption amount is reset to zero or a value representing a lower consumption amount, or the remaining amount is restored to a value representing full ink or approaching full ink.

[0044] From the time when the image forming device supplies power to the consumable chip to the time when the image forming device sends the first instruction to the consumable chip, the reset operation of the consumable chip should be completed. Referring to Figure 3 , after the user re-installs the consumable cartridge, the image forming device supplies power to the consumable chip at t1, and the power supply VCC becomes high. At t2, the clock signal becomes high, and the image forming device sends a control signal to the consumable chip in response to the clock signal. After t1, the consumable chip performs a reset operation, and the reset operation is required to be completed before t2. However, with the update of the printer, the time length is getting shorter and shorter, and the failure rate of the existing reset method is getting higher and higher, which affects the normal use of the printer.

[0045] To solve the above problems, the embodiment of the present application provides a consumable chip, which divides consumable data and consumable backup data into a plurality of corresponding data blocks respectively. The consumable backup data can correspond to all of the consumable data or part of the consumable data. Each data block of the consumable data and the corresponding data block of the consumable backup data form a group of corresponding data blocks, wherein the consumable backup data is reference data of the consumable data. For example, when the consumable data contains consumable remaining amount data, the consumable remaining amount data can be divided into a plurality of blocks, and consumable backup data is stored in the consumable chip, including a plurality of consumable backup remaining amount data corresponding to the consumable remaining amount data in the consumable data. In a plurality of power-on and power-off processes, each time the power is turned on, a reset operation is performed based on a data block in the consumable data, so that the consumable chip is reset to reference data, thereby achieving accurate reset of the consumable chip. In other words, the consumable data is divided into a plurality of blocks, and different data blocks are modified at different power-on times in multiple times, and after multiple executions, the consumable data returns to a state that can represent that the ink cartridge containing the chip is full or close to full.

[0046] Figure 4 A flowchart of a chip reset method provided by the embodiment of the present application is shown. The method can be applied to the consumable chip provided by the embodiment of the present application, as shown in Figure 4 The method can include the following steps.

[0047] Step 401, after being electrically connected with the image forming device, a reset flag is identified.

[0048] Step 402, when the reset flag indicates that the consumable data meets the reset condition, a reset operation is performed multiple times in a power-on and power-off process of a power line between the image forming device and the consumable chip, so that the consumable backup data is updated to the consumable data.

[0049] In actual use scenarios, for the consumable that has been exhausted, the user dismounts the consumable cartridge from the image forming device, and after the consumable is filled, the user re-installs the consumable cartridge to the image forming device. The consumable chip of the embodiment of the present application is provided with a consumable data storage area and a consumable backup data storage area, wherein the consumable data storage area stores consumable data, and the consumable backup storage area stores a plurality of consumable backup data, each of which corresponds to part of the data attribute of the consumable data. Referring to Figure 5The consumable backup storage area stores multiple consumable backup data, including consumable backup data 1, consumable backup data 2, consumable backup data 3, …, and consumable backup data 8. Each piece of consumable backup data corresponds to a part of the data attribute of the consumable data, and the combination of the eight pieces of consumable backup data can constitute a new consumable data. For example, the consumable data contains consumable model, consumable serial number, and consumable remaining amount value information, the consumable backup data 1 can contain the consumable model, the consumable backup data 2 can contain the consumable serial number, …, and the consumable backup data 8 can contain the consumable remaining amount value. The above is only an exemplary description, and in some embodiments, the consumable backup storage area can also contain other numbers of consumable backup data, and different consumable backup data can also record the specified fields of the consumable data in other forms.

[0050] In an optional embodiment, the consumable data includes consumable remaining amount data. One or more pieces of consumable backup data in the consumable backup storage area are backup data corresponding to the consumable remaining amount data. For example, the consumable backup data 1, the consumable backup data 2, and the consumable backup data 3 can be part of the consumable remaining amount data. When the consumable chip performs the reset operation, the consumable remaining amount data can be updated based on the consumable backup data 1, the consumable backup data 2, and the consumable backup data 3, so that the consumable remaining amount data is restored to the factory settings. In other embodiments, the consumable remaining amount data can also correspond to other consumable backup data attributes. For example, when the consumable chip has six pieces of consumable backup data, the first two pieces of consumable backup data can be part of the consumable remaining amount data, which is not limited here.

[0051] The reset flag bit is provided in the consumable chip, and after being electrically connected with the image forming device, the consumable chip can identify the value of the reset flag bit to determine whether the consumable data meets the reset condition. Optionally, the value of the reset flag bit can include a first value and a second value, the first value can represent that the consumable data meets the reset condition, and the second value can represent that the consumable data does not meet the reset condition. In actual scenarios, the first value can be 1 (high level), and the second value can be 0 (low level), and the specific value is not limited.

[0052] In an optional embodiment, the reset flag bit is determined by the consumable chip based on the consumable remaining amount value when the consumable chip is working normally. When the consumable chip detects that the consumable remaining amount value is lower than a preset consumable threshold, the reset flag bit can be modified to the first value. After the user replaces the consumable, the power line between the image forming device and the consumable chip will perform a cycle power-on and power-off process. In this process, the consumable chip can identify the reset flag bit to determine whether the consumable data meets the reset condition.

[0053] When the consumable chip is determined to meet the reset condition, the consumable chip will perform the reset operation multiple times in the power line cycle of power-on and power-off. Specifically, after each power-on of the image forming device, the consumable chip performs the reset operation based on at least one backup consumable data.

[0054] In an alternative embodiment, during the single power-on of the image forming device, the consumable chip obtains the target backup consumable data associated with the current power-on, and then updates the corresponding part of the consumable data based on the target backup consumable data. Specifically, the update process can include: writing the target backup consumable data into the corresponding position of the consumable data storage area to update the corresponding field of the consumable data. After the update is completed, the consumable chip modifies the corresponding identification information to completed. In the cycle reset process, the consumable chip first identifies the identification information to determine whether the last reset operation performed is completed. When the last reset operation performed in the last power-on is completed, the consumable chip obtains the target backup consumable data associated with the current power-on, and when the last reset operation performed in the last power-on is not completed, the target backup consumable data associated with the last power-on is obtained.

[0055] In an alternative embodiment, the consumable chip reset flow can be as shown in Figure 6 The image forming device powers the consumable chip at t1, and VCC becomes high. After the consumable chip is powered on, it reads the backup consumable data 1 in the backup consumable storage area, and then writes the backup consumable data 1 into the corresponding position of the consumable data storage area. Since the backup consumable data 1 is only one-eighth of the size of the consumable data, the consumable chip can complete the writing of the backup consumable data 1 before t2. After a predetermined time, the image forming device stops powering the consumable chip, and VCC becomes low, and the power-on and power-off process is completed. Optionally, after the first reset of the consumable chip is successful, the related identification information (such as the mark position 1) can be modified to indicate that the reset operation of the backup consumable data 1 is completed.

[0056] The image forming device performs the second power-on and power-off process at t3, and powers the consumable chip again. The consumable chip identifies the identification information to determine that the backup consumable information 1 has performed the reset operation, reads the backup consumable information 2, writes the backup consumable information 2 into the corresponding position of the consumable data storage area, and modifies the identification information after completion. If the consumable chip determines that the reset operation of the backup consumable information 1 is not successfully performed according to the identification information, it still reads the backup consumable information 1, writes the backup consumable information 1 into the corresponding position of the consumable data storage area again, and modifies the identification information after completion.

[0057] The subsequent power-on and power-off processes are the same as the above process. The image forming device performs the 8th power-on at t15, and the consumable chip performs the reset operation of the backup consumable data 8, and modifies the identification information after the reset is successful.

[0058] After the complete resetting of the consumable data, the consumable chip can modify the reset flag bit to a second value and normally process subsequent work. During the subsequent normal work process, if the consumable chip detects that the consumable remaining value is lower than the consumable threshold value again, the consumable chip can modify the reset flag bit to the first value again. After the user replaces the consumable again, the consumable chip can identify the reset flag bit to start the next reset process. Under normal circumstances, in the power line cycle power-on and power-off process, the consumable chip cannot directly detect the specific value of the consumable remaining value. Therefore, the consumable chip characterizes the consumable remaining value by modifying the reset flag bit during the last normal work, so that the consumable chip can determine whether the consumable data meets the reset condition.

[0059] In the embodiment of the application, the consumable backup data is divided into 8 parts, and each time the power is turned on, only 1 part of the consumable backup data is used to update the corresponding part of the consumable data. The time spent by the consumable chip in updating the corresponding part of the consumable data based on the target consumable backup data is less than the duration of a single power-on in the cycle power-on and power-off process. Therefore, the overall reset of the consumable data can be realized in the multiple cycle power-on and power-off process, and the success rate of the reset of the consumable chip is improved.

[0060] In an optional embodiment, the total number of parts of the consumable backup data can be flexibly set based on the number of times of cycle power-on and power-off of the image forming device. For example, when the image forming device performs 10 times of power-on and power-off after starting, the consumable backup data can be divided into 8 parts. When the image forming device performs 8 times of power-on and power-off after starting, the consumable backup data can be divided into 6 parts. The number of parts of the consumable backup data is usually less than the number of times of power-on and power-off of the image forming device. Even if a reset operation fails, the overall reset operation of the consumable chip can be ensured to be successfully completed as much as possible.

[0061] In an alternative embodiment, the identification information can be implemented by a flag bit. The flag bit is initially set to 0, and when the consumable chip completes resetting the consumable backup data 1, the flag bit can be set to 1. Thereafter, when the consumable chip completes resetting the consumable backup data 2, the flag bit can remain unchanged and still be set to 1. Otherwise, if the consumable chip fails to reset the consumable backup data 2, the flag bit is set to 0. After the consumable chip completes resetting the consumable backup data 8, the flag bit remains set to 1. In another alternative embodiment, the identification information can be implemented by two flag bits, including a first flag bit and a second flag bit. The first flag bit has the same function as the above-described flag bit, and is set to 1 after any consumable backup data is successfully reset, and is set to 0 after any consumable backup data fails to be reset. The second flag bit is initially set to 0, and is set to 1 after the consumable chip completes overall resetting, indicating that the resetting operation of the consumable chip has been completed. In another alternative embodiment, the identification information can be implemented by 8 flag bits, and each consumable backup data is provided with a corresponding flag bit. After any consumable chip completes resetting, the corresponding flag bit is set to 1, otherwise it is set to 0. By providing each consumable backup data with a corresponding flag bit, the actual situation of the resetting operation can be more accurately known, and the resetting efficiency can be improved. The specific implementation of the identification information can be flexibly set based on the operation requirements, which is not limited herein.

[0062] In an alternative embodiment, the consumable has a certain service life and cannot be used permanently without limit. Therefore, the resetting of the consumable chip is limited in number of times. The above-described complete resetting of the 8 consumable backup data can be regarded as one complete resetting operation of the consumable chip, and the consumable chip can record the number of historical resetting times. When modifying the resetting flag bit, the consumable chip needs to detect not only the consumable remaining amount value but also the number of previous resetting operations of the consumable chip. When the consumable remaining amount value is lower than the consumable threshold value and the number of previous resetting operations of the consumable chip is less than a preset number of resetting times, the resetting flag bit is modified to a first value. It can be understood that the use of the consumable is limited in service life, and when the number of previous resetting operations of the consumable chip exceeds the preset number of resetting times threshold value, it can be considered that the service life of the consumable has been exhausted, and if the consumable device continues to be used, it can cause mechanical failure and needs to be limited to continue to be used.

[0063] The embodiments of the present application also provide a consumable cartridge, which is provided with the consumable chip described in the above-described embodiments, and when a user installs the consumable cartridge into an image forming device, the consumable chip can perform the above-described resetting operation.
