Memory chip reset method and imaging device

Abstract

The present invention proposes a method for resetting a memory chip and an imaging device. The method for resetting a memory chip includes: acquiring the data change mode of the consumable chip; acquiring the consumable information storage area and non-access area of ​​the consumable chip; according to the data change mode Rewriting the data values ​​stored in the consumables information storage area and the non-access area, wherein, rewriting the stored data values ​​in the consumables information storage area is the initial data value, and changing the data values ​​stored in the non-access area according to the data change mode; wherein , the address of the non-access area is adjacent to the address of the consumables information storage area. The storage chip resetting method of the present invention, by acquiring the data change mode of the consumable chip and the consumable information storage area and non-access area of ​​the consumable chip, rewrites the data values ​​of the consumable chip access area and non-access area according to the rewriting rules to realize the storage chip reset.

Description

technical field [0001] The invention relates to the field of chip technology, in particular to a method for resetting a memory chip and an imaging device. Background technique [0002] Imaging equipment, such as printers, photocopiers, fax machines, word processors or multi-functional all-in-one machines, etc., are equipped with detachable consumable boxes that are convenient for users to replace. Usually, consumable chips need to be installed on the consumable boxes. Through the consumable chips and The imaging device communication of the imaging device enables the imaging device to ideally use the consumable box and its consumables such as toner and ink. The consumables chip stores the program and consumables box data, and the consumables box data can include version number, model, remaining consumables, etc. [0003] With the popularization of imaging equipment, the consumption of imaging equipment consumables is also increasing, but after the toner cartridge or the tone...

AI Technical Summary

Problems solved by technology

[0003] With the popularization of imaging equipment, the consumption of imaging equipment consumables is also increasing, but after the toner cartridge or the toner in the ink cartridge is consumed, the remaining amount of consumables recorded in the consumable chip will become zero, resulting in The chips on the toner cartridge or ink cartridge are discarded together with the waste toner box and cannot be reused, resulting in waste

[0004] Although the chip recycler will reset the discarded old chips to realize the reuse of discarded chips, the existing reset method, for the old chips with a high degree of encryption, has a low reset success rate, which will still cause chip damage. waste
