Consumable chip and its data recovery method, consumable container, imaging device

Abstract

The invention provides a consumptive material chip. The consumptive material chip comprises a storage unit, an interface unit, a control unit, an error detecting part and a directing logic part, wherein the storage unit comprises a parameter region and a metering region; the metering region comprises more than two standby metering regions; data which can be identified by an imaging device is stored in each standby metering region; the interface unit provides an interface or a protocol for data communication; the control unit is connected with the storage unit and the interface unit respectively for controlling data operation of the storage unit and the interface unit; the error detecting part is connected with the storage unit for detecting whether the data in the standby metering regions is damaged or not, and storing the result; and the directing logic part is connected with the storage unit and the control unit respectively, and used for reading the value of the error detecting part and directing the corresponding standby metering regions by the control unit. According to the invention, the damaged chip data can be remedied.

Description

technical field [0001] The present invention relates to a chip and a method for remediating data damage thereof, in particular, to a consumable chip used in a consumable container and a method for remediating data damage thereof. The present invention also relates to a consumable container equipped with the above consumable chip, an imaging equipment. Background technique [0002] Existing imaging equipment includes printers, copiers, fax machines and multi-functional all-in-one machines. The two commonly used printers are inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to provide printers with ink for printing. , to form text or patterns that need to be printed on paper; laser printers use a toner cartridge containing toner as a consumable container to provide toner for printing to the printer to form text or patterns that need to be printed on the medium, copiers , The imaging principle of the fax machine and...

Problems solved by technology

Figure 5 It shows the data stored in the consumable chip 23 of the existing toner cartridge. The address 0X05~0X0B is the parameter area, including the model of the toner cartridge, page output, manufacturer code and other parameter data. After the printer is powered on, read the parameter area to determine whether the toner cartridge is suitable for this printer; the address 0X0C~0X13 is the metering area, which stores metering data such as the number of printed pages and the percentage of remaining toner, and the printer will print according to the Recalculate the consumption situation of the computer, and then re-update the calculation result to the metering area; usually, the storage operation of the consumable chip on the memory is: read the data in the data block to be operated, and then modify the corresponding part of the above data to the one that needs to be stored Data, then erase the memory, and finally write the modified data into the memory. The above-mentioned read-modify-erase-write process takes at least a few milliseconds, and some even takes tens of milliseconds. During this process, if If the write operation is not completed after erasing, and abnormal conditions such as printer power failure or printing errors occur, the data in the chip of the consumable will be damaged, and the printer will not be able to recognize the ink cartridge or toner cartridge, and the ink cartridge or toner cartridge will not be able to Continued use causes waste and pollution; during the working process of the printer, customers sometimes open the printer cover to take out the ink cartridge or toner cartridge. Lost, the ink cartridge or toner cartridge cannot be recognized by the printer after installation; even some printers have been supplying power to the chip, and when installing or removing the toner cartridge or ink cartridge, they often encounter ink cartridges or toner The memory data of the consumable chip of the cartridge is scrambled, that is, the data is all 0XFF, which also leads to the situation that the ink cartridge or toner cartridge cannot be recognized by the printer after installation.

Since the printer will repeatedly read and write the data in the metering area during the working process, the data in 0X0C~0X13 will change with the printing process. When the erasing of the writing operation is completed, no data is written, and at this time the power is off. or the user is taking out the toner cartridge, the data in the metering area will be as Image 6 As shown in , 0X0C~0X13 all become 0XFF or part of the data is 0XFF. At this time, the data in the consumable chip has been destroyed. When the printer is powered on again, the consumable chip cannot be recognized by the printer, resulting in carbon The powder box can no longer be used, causing inconvenience to users

Therefore, it is necessary to provide a consumable chip that can still be used even if the data is damaged, so as to avoid problems such as various printing interruptions caused by the printer not being able to recognize the consumable chip in the above-mentioned various situations
