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

Embodiment Construction

[0022] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0023] The communication rules between imaging devices such as printers and consumable chips are as follows: when the printer is turned on, the printer and consumable chips pass a certain communication protocol, such as IIC (Inter-Integrated Circuit, integrated circuit bus), UART (Universal Asynchronous Receiver / Transmitter, universal Asynchronous transceiver transmitter) communicates with the consumable chip, and then verifies the legitimacy of the consumable box and the information about the consumable box stored in the consumable chip. The legitimacy of the consumables box is mainly reflected by some encryption algorithms. That is to say, the data values ​​of the printer and the consumable chip are encrypted, and the data value can be decrypted only by ...

Abstract

The invention provides a memory chip reset method and imaging equipment. The memory chip reset method comprises the steps that a data change mode of a consumable chip is acquired; a consumable information memory area and a non-access area of the consumable chip are acquired; the data values stored in the consumable information memory area and the non-access area are rewritten according to the datachange mode, wherein the data values stored in the consumable information storage area are rewritten into initial data values, and the data values stored in the non-access area are changed accordingto the data change mode; and the address of the non-access area is adjacent to the address of the consumable information storage area. According to the memory chip reset method, the data values of theaccess area and the non-access area of the consumable chip are rewritten according to rewriting rules by acquiring the data change mode of the consumable chip and the consumable information storage area and the non-access area of the consumable chip, and resetting of the memory chip is achieved.

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...
