Consumable chip resetting method and device

Abstract

The invention provides a consumable chip resetting method and device. The data written into a consumable chip are composed of a big data block and a small data block. The consumable chip resetting method comprises the following steps that the big data block is written into the consumable chip; whether the big data block is completely written into the consumable chip or not is detected; if a detection result is that the big data block is completely written into the consumable chip, the detection result is recorded, and the detection result is taken as a judgment mark for deducting points, and taken as a judgment mark that the big data block does not need to be re-written when the resetting operation is repeated; the small data block is written into the consumable chip; and whether the smalldata block is completely written into the consumable chip or not is detected. According to the device and the method, the possibility that reset equipment is interfered can be reduced, and the resetefficiency of the consumable chip is improved.

Description

technical field [0001] The invention relates to the technical field of printing and imaging, in particular to a method and device for resetting consumable chips. Background technique [0002] When the chip reset device resets the chips of the consumables, it generally follows the principle of deducting points. If the reset device successfully resets a chip, the device will deduct certain points accordingly. If the total points of the reset device are used up, it is necessary to purchase points from the manufacturer of the reset device. [0003] Consumable chips for printers (laser printers, inkjet printers or all-in-ones), which store information related to printing consumable boxes (ink cartridges, toner cartridges, toner cartridges, etc.), and their main functions are for identification and recording of usage status . The printing supply box is detachably installed on the main body of the printer, and when the recording materials (such as ink and toner) in the supply bo...

Problems solved by technology

[0006] However, someone will interfere with the detection mechanism during the detection step, causing the detection to fail

The consequence of this interference is that the data of the consumable chip has been written in, and the consumable chip has been written successfully in theory, but in order to confirm the success of the reset device, the data will be read out for comparison and confirmation. This process will leave hidden dangers for cheating. Someone can pass Interference or other means of cheating leads to the failure of the test, and the reset device will not deduct points, which will cause economic losses to the manufacturer of the reset device

[0007] After this reset method is disturbed, the reset device cannot clearly know the progress of the reset, and thus cannot record whether the reset operation is really successful. As a result, the reset device may reset and write data repeatedly, resulting in long operation time and low writing efficiency. The problem
