Chip, data communication method for chip, consumable container and imaging equipment

Abstract

The invention provides a chip of a consumable container, which comprises a storage module, a control module, an interface module and a data safety module. The storage module is used for storing initial data, printing data, control data and key data; the interface module is used for realizing data communication between the storage module and the control module; the data safety module is respectively connected with the interface module and the control module, and is used for identifying a type and a content of data communicated between a printer and the chip, encrypting matched data in a selected safe mode and decrypting the data; the control module is connected with the storage module and is used for controlling data communication between the chip and the printer and the access operation of the data of the storage module and external data and sending a corresponding control command to the chip according to a safety module processing result so as to realize data communication; and the same keys are stored in the printer and the chip. The invention also provides a data communication method for the chip, the consumable container with the chip structure, and imaging equipment with the consumable container. The safety of the communication data of the chip can be protected.

Description

technical field [0001] The present invention relates to a chip, a chip data communication method, a consumable container installed with the chip, and an imaging device, in particular, to a memory chip, a data communication method between the memory chip and the imaging device, and a consumable container installed with the memory chip and imaging equipment. Background technique [0002] Imaging equipment is equipment that realizes the image transfer process, such as electrostatic copiers or printers, which are widely used in various office places. Among them, printers are widely used in office places and homes because of their diverse functions and convenient use. Currently, they are commonly used The two types of printers in China are: inkjet printers and laser printers. The consumables of inkjet printers are ink, and the ink is contained in ink cartridges that can be assembled and disassembled in inkjet printers. To form images or text on the media to be printed; the consu...

AI Technical Summary

Problems solved by technology

It can be seen from the above that the printer exchanges data with the chip on the consumable container many times from power-on to use to obtain information or update information. However, during the data exchange process between the printer and the chip, the data information is often affected by external Interference, such as: power supply interference, electromagnetic interference or malicious cracking attacks by external customers, etc., which will cause the chip to perform wrong operations or store data errors, and then cause the printer to generate recognition errors and continue to execute printing commands, resulting in damage to the printing device
