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 to achieve the reuse of the consumable chip. The existing consumable chip reset method is: 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 prompt to replace the ink cartridge. At this time, the user can unplug 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

[0015] In an optional embodiment, when the reset operation performed by the last power-on is completed, the target consumable backup data is the consumable backup data associated with the current power-on; when the reset operation performed by the last power-on is not completed, the target consumable backup data is the consumable backup data associated with the last power-on;

[0016] Whether the reset operation performed each time the power is turned on is completed is determined by the corresponding identification information.

[0036] Common image forming devices are usually equipped with a detachable consumable box, which contains consumables (such as ink, toner, etc.) and a consumable chip for recording consumable data is installed on the shell of the consumable box. Figure 1 The image forming device may include: an image forming device and a consumable box. The image forming device is used to perform operations related to image formation to output a printed image. The consumable box 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, or a dot matrix printer, the consumable box is an ink cartridge, a toner cartridge, a toner cartridge, a toner cartridge, a ribbon cartridge, etc.

[0037] In an achievable embodiment, the consumable box may be a developer box, and the developer box includes a developer container and a developer conveying element. The developer container is used to contain a developer such as toner, and the developer conveying element is a component such as a powder feeding roller and a powder feeding screw for stirring and / or conveying toner. The developer box may also include only a developer container or a 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 communication. The communication connection can be a communication connection through a contact, an antenna or a coil, and the embodiment of the present application is 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: printing 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 life, etc. 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 embodiment of the present application is not limited to this.

[0039] Figure 2 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 containing 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, it reaches 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 containing portion 11 is used to contain the developer, and the developer may be a material 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] Usually, the image forming device is detachably mounted with at least one consumable material. Figure 2 As an example, the image forming device shown in FIG. 1 is detachably mounted with four consumables (respectively Figure 2 The consumables 1, 2, 3 and 4 shown are used to provide four colors of developers, namely black K, cyan C, magenta M and yellow Y, to the image forming device respectively. Of course, in other embodiments, the number of consumables installed in the image forming device may be increased or decreased, for example, to 5 or 6 or even more or less, etc., and the present application does not limit this.

[0041] The consumable chip stores a consumable remaining value, which corresponds to the remaining amount of consumables in the consumable box. When the consumables are used up (the consumable remaining value is lower than a preset value), the image forming device can output a prompt message for replacing the consumables to remind the user to remove the consumable box and fill it with new consumables. Optionally, the image forming device can output a first prompt message to prompt the user to replenish the consumables. The specific method of outputting the first prompt message 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 connected to a user device such as a smart phone in communication, and the first prompt message can also be sent to the user through the user device.

[0042] Specifically, with regard to the specific method for the image forming device to determine that the remaining value corresponding to the consumable chip is lower than the consumable threshold, in one embodiment, the image forming device obtains 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 has a pre-stored consumable threshold. When the consumable chip determines that the remaining value stored in 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 notify 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 consumables and reinstalls the consumable box into the image forming device, the image forming device supplies power to the consumable chip, and the consumable chip performs a reset operation after powering on, so that the consumable data is restored to the factory settings or close to the factory settings to achieve reuse. For example, the consumable data includes the usage information of the consumables, and the usage information can be the consumption or remaining amount of the consumables. During the reset process, the consumption is reset to zero or restored to a value representing a lower consumption, or during the reset process, the remaining amount is restored to data representing that the ink is full or close to full.

[0044] The reset operation of the consumable chip should be completed from the time the image forming device supplies power to the consumable chip to the time the image forming device sends the first command to the consumable chip. Figure 3 After the user reinstalls the consumable box, the image forming device powers on the consumable chip at time t1, and the power supply VCC becomes high. At time 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 time t1, the consumable chip performs a reset operation, and the reset operation is required to be completed before time t2. However, with the update of the printer, this time length is getting shorter and shorter, and the failure rate of the existing reset method is getting higher and higher, affecting the normal use of the printer.

[0045] In view of the above problems, an embodiment of the present application provides a consumable chip, which divides consumable data and consumable backup data into multiple corresponding data blocks respectively. The consumable backup data may correspond to all of the consumable data or to part of the consumable data. Each data block of the consumable data and the data block of the consumable backup data corresponding to it form a group of corresponding data blocks, wherein the consumable backup data is the reference data of the consumable data. For example, when the consumable data contains consumable remaining data, the consumable remaining data may be divided into multiple blocks, and the consumable backup data is stored in the consumable chip at the same time, including multiple blocks of consumable backup remaining data corresponding to the consumable remaining data in the consumable data. In multiple power-on and power-off processes, each power-on is based on a data block in the consumable data to reset it to the reference data, thereby realizing accurate resetting of the consumable chip. In other words, the consumable data is divided into multiple blocks, and different data blocks are modified multiple times at different power-on times. After multiple executions, it is restored to a state that can represent that the ink cartridge containing the chip is full of ink or close to full of ink.

[0046] Figure 4 Schematic diagram of a chip reset method provided in an embodiment of the present application. The method can be applied to the consumable chip provided in an embodiment of the present application, such as Figure 4 As shown, the method may include:

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

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

[0049] In actual usage scenarios, for exhausted consumables, the user removes the consumable box from the image forming device, and after the consumables are filled, the user reinstalls the consumable box 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 is stored in the consumable data storage area, and the consumable backup storage area stores multiple copies of consumable backup data, each copy of the consumable backup data corresponds to part of the data attributes of the consumable data. Figure 5The consumable backup storage area stores multiple copies of consumable backup data, including: consumable backup data 1, consumable backup data 2, consumable backup data 3, ..., consumable backup data 8. Each copy of consumable backup data corresponds to a part of the data attributes of the consumable data, and the eight copies of consumable backup data can be combined to form a new consumable data. For example, the consumable data contains information such as the consumable model, the consumable serial number, and the consumable remaining value. The consumable backup data 1 may contain the consumable model, the consumable backup data 2 may contain the consumable serial number, ..., and the consumable backup data 8 may contain the consumable remaining value. The above is only an exemplary description. In some embodiments, the consumable backup storage area may also contain other numbers of consumable backup data, and different consumable backup data may also record designated fields of the consumable data in other forms.

[0050] In an optional embodiment, the consumable data includes: consumable remaining data. One or more consumable backup data in the consumable backup storage area are backup data corresponding to the consumable remaining data. For example, the above-mentioned consumable backup data 1, consumable backup data 2 and consumable backup data 3 may be parts of the consumable remaining data respectively. When the consumable chip performs a reset operation, the consumable remaining data may be updated based on the consumable backup data 1, consumable backup data 2 and consumable backup data 3 to restore the consumable remaining data to the factory settings. In other embodiments, the consumable remaining data may also correspond to other consumable backup data attributes. For example, when the consumable chip has a total of 6 consumable backup data, the first two consumable backup data may be parts of the consumable remaining data respectively, which is not limited here.

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

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

[0053] When it is determined that the consumable chip meets the reset condition, the consumable chip will perform the reset operation multiple times during the power line power cycle process. Specifically, after the image forming device is powered on each time, the consumable chip performs the reset operation based on at least one consumable backup data.

[0054] In an optional embodiment, during a single power-on process of the image forming device, the consumable chip will obtain the target consumable backup data associated with this power-on, and then update the corresponding part of the consumable data based on the target consumable backup data. Specifically, the update process may include: writing the target consumable backup data to 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. During the cyclic reset process, the consumable chip first identifies the identification information to determine whether the reset operation performed last time has been completed. When the reset operation performed at the last power-on has been completed, the consumable chip obtains the target consumable backup data associated with this power-on, and when the reset operation performed at the last power-on is not completed, the target consumable backup data associated with the last power-on is obtained.

[0055] In an optional embodiment, the consumable chip reset process can be as follows: Figure 6 As shown. The image forming device supplies power to the consumable chip at time t1, and VCC becomes a high level. After the consumable chip is powered on, the consumable backup data 1 is read in the consumable backup storage area, and then the consumable backup data 1 is written to the corresponding position of the consumable data storage area. Since the consumable backup data 1 is only one eighth of the size of the consumable data, the consumable chip can complete the writing operation of the consumable backup data 1 before time t2. After a preset period of time, the image forming device stops supplying power to the consumable chip, VCC becomes a low level, and the power-on and power-off process ends. Optionally, after the consumable chip is successfully reset for the first time, the relevant identification information (such as mark position 1) can be modified to indicate that the reset operation of the consumable backup data 1 has been completed.

[0056] The image forming device performs the second power-on and power-off process at time t3, and supplies power to the consumable chip again. The consumable chip identifies the identification information to determine that the consumable backup information 1 has been reset, reads the consumable backup information 2, writes the consumable backup information 2 to 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 consumable backup information 1 has not been successfully executed according to the identification information, the consumable backup information 1 is still read, and the consumable backup information 1 is written to the corresponding position of the consumable data storage area again, and the identification information is modified after completion.

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

[0058] After all the consumable data has been reset, the consumable chip can modify the reset flag to the second value and handle subsequent work normally. During the subsequent normal operation, if the consumable chip detects that the consumable remaining value is lower than the consumable threshold again, the consumable chip can modify the reset flag to the first value again. After the user replaces the consumable again, the consumable chip can recognize the reset flag to start the next reset process. Normally, in the power cord power cycle 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 when it worked normally last time, so that the consumable chip can determine whether the consumable data meets the reset conditions.

[0059] In an embodiment of the present application, by dividing the consumable backup data into 8 parts, each time the power is turned on, the corresponding part of the consumable data is updated based on only one copy of the consumable backup data. The time spent on 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 cyclic power-on and power-off process. Therefore, the overall reset of the consumable data can be achieved in the power-on and power-off process with multiple cycles, thereby improving the success rate of the consumable chip reset.

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

[0061] In an optional embodiment, the above-mentioned identification information can be implemented by a mark bit. The mark bit is initially set to 0. When the consumable chip completes the reset of the consumable backup data 1, the mark bit can be set to 1. Afterwards, when the consumable chip completes the reset of the consumable backup data 2, the mark bit may not be changed, and the mark bit is still set to 1. On the contrary, if the reset of the consumable backup data 2 fails, the mark bit is set to 0. After the reset of the consumable backup data 8 is completed, the mark bit is still set to 1. In another optional embodiment, the above-mentioned identification information can be implemented by two marks, including a first mark bit and a second mark bit. The first mark bit has the same function as the above-mentioned mark 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 mark bit is initially set to 0. After the overall reset of the consumable chip is completed, the second mark bit can be set to 1, indicating that the reset operation of the consumable chip has been completed. In another optional embodiment, the above-mentioned identification information can be implemented by 8 marks, and a mark bit is set for each consumable backup data. After the reset of any consumable chip is completed, the corresponding mark bit can be set to 1, otherwise it is set to 0. By setting a corresponding mark bit for each consumable backup data, the actual situation of the reset operation can be known more accurately, and the reset efficiency can be improved. The specific implementation of the identification information can be flexibly set based on the operation requirements and is not limited here.

[0062] In an optional embodiment, the consumables have a certain service life and cannot be used permanently indefinitely. Therefore, there is a limit on the number of times the consumable chip can be reset. The above-mentioned reset of all 8 copies of the consumable backup data can be regarded as a reset operation of the consumable chip, and the consumable chip can record the number of historical resets. When modifying the reset flag, in addition to detecting the consumable remaining value, the consumable chip also needs to detect the number of previous resets. When the consumable remaining value is lower than the consumable threshold and the number of reset operations previously performed by the consumable chip is less than the preset number of resets, the reset flag is modified to the first value. It can be understood that the use of consumables has a certain life limit. When the number of reset operations performed by the consumable chip exceeds the preset reset number threshold, it can be considered that the life of the consumable has expired. If it continues to be used, it may cause mechanical failure, and the consumable device needs to be restricted from continued use.

[0063] The embodiment of the present application further provides a consumable box, in which the consumable chip described in the above embodiment is installed. When the user installs the consumable box into an image forming device, the consumable chip can perform the above reset operation.
