Abstract

The invention provides a data rewriting device for a consumable chip and a working method of the data rewriting device. The rewriting device comprises a shell, wherein a control unit and a memory unit accessed by the control unit are arranged inside the shell; an electric connector electrically connected with an electric contact of the consumable chip is arranged on the rewriting device, and electrically connected with the control unit; more than two groups of consumable chip serial number data are stored in the memory unit; the control unit is provided with a serial number marking unit; the serial number marking unit is used for processing the serial number data written into the consumable chip by marks. The working method comprises the following steps: writing a group of serial number data into the memory of the consumable chip, and processing the serial number data by marks after electrically connecting the electric connector with the electric contact of the consumable chip. By adopting the data rewriting device, the serial number data stored in the consumable chip can be rewritten, and the condition that after a consumable container filled with a consumable is mounted on a printer, printing cannot be performed is avoided.

Description

technical field [0001] The invention relates to the field of data rewriting, in particular to a data rewriting device for a consumable chip and a working method of the device. Background technique [0002] As a common office equipment, printers provide great convenience for modern office. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to spray ink on paper to form text or patterns that need to be printed on paper; laser printers use ink cartridges containing toner The toner cartridge is used as a consumable container to form text or patterns that need to be printed on the medium. [0003] see figure 1 , an existing color inkjet printer has a casing 11, figure 1 The inkjet printer is shown with the chassis 11 omitted. The machine core 12 of ink-jet printer is provided with in the casing 11, and is provided with a slide bar, print word car 14 in motor ( figure 1 (not visible...
