Imaging box chip, imaging box and method for replacing serial numbers of imaging box chip

Abstract

The invention discloses an imaging box chip, an imaging box and a method for replacing serial numbers of the imaging box chip. The imaging box chip comprises a communication module, a nonvolatile-data storage module, a volatile-data temporary storage module and a control module; the nonvolatile-data storage module stores information of at least two different serial numbers, and the volatile-data temporary storage module comprises at least two data temporary storage elements; the control module loads the information of the different serial numbers to the corresponding data temporary storage elements under the preset condition; when an imaging device is required to read serial number information of the chip, the serial number information in the designated data temporary storage elements is sent to the imaging device through the communication module, and the control module can judge whether the serial number information sent to the imaging device passes through the validity verification of the imaging device or not; and if the serial number information sent to the imaging device does not pass through the validity verification of the imaging device, serial number information of the other data temporary storage element is sent to the imaging device. When the imaging box chip replaces the serial numbers, the chip cannot be affected by a bus timing sequence of the imaging device.

Description

technical field [0001] The invention relates to the technical field of imaging, in particular to an imaging box chip, an imaging box and a method for replacing the serial number of the imaging box chip. Background technique [0002] With the development of imaging technology, imaging devices such as copiers, printers, facsimile machines, and word processors have been widely used. Imaging devices are equipped with imaging cartridges (such as ink cartridges and toner cartridges) that are convenient for users to replace to accommodate recording materials (such as ink and toner), and imaging cartridges are usually provided with imaging cartridge chips. [0003] Raw data related to the imaging box and usage data generated during the imaging process are stored in the imaging box chip. Wherein, the original data related to the imaging box may be such data as the manufacturer code, production date, model and characteristic parameters of the imaging box. The usage data generated du...
