Problems solved by technology

[0006] In order to solve the problems in the prior art of using flags to mark the currently used serial number, resulting in the use of additional chip storage space and error-prone problems in reading and writing memory, the present invention provides a chip control method for printer consumables, which does not require additional storage space. There will be no serial number marking errors due to unexpected power failure of the printer, and the solution is simple, easy to implement, and easy to promote

Embodiment Construction

[0050] Such as figure 1 As shown, the schematic diagram of the consumable chip structure, figure 2 It is a schematic diagram of the structure of the consumable chip storage module. The consumables chip includes a logic module and a storage module in terms of architecture. The logic module controls the work flow and achievable functions of the chip, and the storage module stores the necessary data of the chip, such as date, ink volume, serial number and other data. The serial number is stored in the memory module of the chip to record the serial number for the printer. In the existing technology, consumable cartridges with mismatched models cannot be installed into the printer because of their different structures; even if the structures are the same, but the sales regions are different, the consumable cartridges installed in the printer will also be in the self-test process of the printer. If it is detected in the chip, it will not be powered; so for consumable chips, the c...

Abstract

The invention provides a chip control method for printer consumables, which does not require additional storage space, does not cause the problem of serial number marking errors due to accidental power failure of the printer, and has a simple scheme, convenient implementation, and easy popularization. In the technical solution of the present invention, instead of using the marking bit, the chip serial number is used as a judgment criterion; in the self-test process of the consumable chip, all serial numbers are verified from the first serial number, The serial number that passes the verification will be sent to the printer for legality judgment; the serial number that is judged to be illegal by the printer will be changed to an illegal serial number, and will not pass the verification in the next power-on self-test process, and will not be transmitted again to the printer.

Description

technical field [0001] The invention relates to the field of printing and imaging technology, in particular to a method for controlling a printer consumable chip. Background technique [0002] In modern intelligent printing and imaging equipment, in order to achieve intelligent control, a chip is often set on the consumables such as ink cartridges and toner cartridges, and each chip is assigned a serial number as a unique ID. The printing and imaging equipment will verify the validity of the consumable box through this serial number, for example: once a certain serial number is marked as a consumable box that has run out of consumables, or the serial number is judged to be a consumable that does not match the consumable model applicable to the printer cartridge, the printer will judge that the consumable cartridge is illegal, and then refuse to use the consumable cartridge. [0003] In order to manufacture consumable cartridges that can be recycled, manufacturers need to so...
