Serial number memory removable consumable chip, consumable and system and application method

Abstract

The invention belongs to the printing field, and particularly relates to a serial number memory removable consumable chip, consumable and system and an application method. The above technique purpose can be achieved through the following technical scheme that the serial number memory removable consumable chip comprises a logical processing unit, a data storage unit and an interface communication unit; the data storage unit comprises a serial number block, a first imaging data block and a second imaging data block; and the first imaging data block and the second imaging data block store consumable residual amount data. Providing the serial number memory removable consumable chip, consumable and system and the application method is the purpose. The chip comprises the normally reading first imaging data block and the second data block in which data are kept unchangeable, the printer does not permanently store the consumable serial number data used at present, and the using expandability and universality of the universal consumable are improved.

Description

technical field [0001] The invention belongs to the field of printing, and in particular relates to a consumable chip with a serial number memory that can be cleared, a consumable, a system and a use method. Background technique [0002] With the popularization of office automation, printing equipment has become an indispensable equipment in office activities. In the printing process, imaging equipment and consumables matching the imaging equipment are required. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to spray ink on paper to form text or patterns that need to be printed on paper; laser printers use ink cartridges containing toner The toner cartridge is used as a consumable container to form text or patterns that need to be printed on the medium. Based on this, in inkjet printing technology, consumables are ink cartridges, which consume the amount of ink in the cartridg...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there is a situation where the serial number and ink volume or toner volume are bound to memory, that is, the printer will store the serial number of the used ink cartridge and the matching ink volume information, and this situation will produce two defects , On the one hand, after the ink is consumed in such a design, the user can only discard the ink cartridge, which not only causes waste of the shell and chip of the ink cartridge, but also causes environmental pollution. It will cause the printer to identify the serial number and ink level information incorrectly, and cannot be used normally

On the other hand, manufacturers of general-purpose consumables can only use the consumables by collecting serial numbers. However, the amount of serial number data collected is limited, and serial number conflicts will still occur, causing the printer to fail to work normally.
