Abstract: The present disclosure provides a consumable chip, a consumable cartridge, a verification method, and a method of using the consumable chip. The consumable chip includes a storage module, configured to store verification data, where the verification data at least includes first verification data and second verification data; and a communication module, configured to output the first verification data if an access instruction for verification data is received within a first time interval, and output the second verification data if the access instruction for verification data is received within a second time interval.

Abstract: Provided are a storage chip, an imaging cartridge, a method for changing a serial number and a method of using the storage chip. The storage chip includes a communication unit, a control unit and a storage unit; the storage unit stores information of multiple different serial numbers and mark information or access mark information about whether a currently-selected serial number is legal; the control unit determines whether the serial number information sent to the imaging device is determined as legal according to a preset strategy and autonomously changes the selected serial number information when a preset condition is satisfied according to the determination result, so that the method of changing the serial number of the storage chip is more convenient, user experience is greatly improved and the problem that the storage chips are unusable because of the same serial number can be solved.

Abstract: The present disclosure discloses a supply assembly of an imaging device, a chip thereof, and a method for updating a slave address of the supply assembly. The method comprises: receiving, by the supply assembly, an address change instruction from the imaging device, the address change instruction including the slave address of the supply assembly; and gathering, by the supply assembly, upon first monitoring an addressing instruction after detection of the address change instruction, a second slave address contained in the addressing instruction first monitored, updating the slave address of the supply assembly into the second slave address, and sending acknowledging data to the imaging device. The supply assembly and its chip according to the present disclosure can rapidly respond to the instructions from the imaging device so as to perform the address change, and manufacturing costs thereof are also reduced.
