Chip version switching method, switching device and switching system

Abstract

The present invention provides a chip version switching method, switching device and switching system. The switching method includes after accessing the flag bit of the version information, and judging whether the flag bit is empty; if the judging result of the first judging step is no , then replace the version information in the chip data according to the tag bit; after the first part of the chip data address bit is accessed, modify the tag in the tag bit to the version setting tag and write the version setting in or in the tag bit Marking: judging whether the second part of the address bit of the chip data is accessed; if the judgment result of the second judging step is yes, erasing the version setting flag in the flag bit. The chip version switching method, switching device and switching system of the present invention match the version information of the chip with the version information of the imaging device by accessing the address bits in the chip data, so that the chip can be used universally for imaging devices of different versions, And the present invention has strong anti-upgrade ability.

Description

technical field [0001] The invention relates to the communication field, in particular to a version switching method of a consumable chip, a version switching device of a consumable chip, and a version switching system of a consumable chip. Background technique [0002] Current imaging equipment such as printers, copiers, fax machines, and multi-functional ones usually include lasers and inkjet types. Consumable containers such as powder / ink cartridges applied to imaging devices usually need to be installed with a chip. After the imaging device communicates with the chip normally, the imaging device can normally use the consumables in the consumable container. For example, the consumables can be ink or toner. [0003] The chip can be used to store the communication data required for communication between the imaging device and the chip, realize the communication protocol and communication method between the imaging device and the chip, etc. The chip can also be used to store...

AI Technical Summary

Problems solved by technology

After the firmware of some imaging devices is upgraded, the number of times the imaging device accesses the chip will also change, which will cause the chip that could be used to be unusable due to the firmware upgrade.

Therefore, the existing method may lead to the fact that the chip is originally suitable for the corresponding version of the imaging device, and the ability to resist firmware upgrades is poor.
