Chip, consumable container and working method of chip

Abstract

The invention provides a chip, a consumable container and a working method of the chip. The chip comprises a substrate, wherein a communication module, a microcontroller and a memory are arranged on the substrate; remaining amount data of a consumable in the consumable container, an updating flag bit and a consumable remaining amount preset value are stored in the memory; identifier values which decrease in one way are stored at the updating flag bit; and the microcontroller is provided with a consumable remaining amount judgment unit for judging whether the consumable remaining amount is zero and an updating control unit. The method comprises the following steps of: judging whether the updating of the consumable remaining amount data is permitted according to the identifier value stored at the flag bit after the chip is electrified; if the updating is permitted, judging whether the consumable remaining amount data is zero by the consumable remaining amount judgment unit; and if the consumable remaining amount data is zero, updating the consumable remaining amount data to the consumable remaining amount preset value and performing decrement operation on the identifier values stored at the flag bit. Thus, the consumable in the consumable container can be fully consumed, and a printer can recognize a compatible consumable container so as to contribute to the use of the compatible consumable container.

Description

technical field [0001] The invention relates to a chip, a consumable material container and a working method of the chip, in particular to a chip mounted on a printing consumable container, a consumable material container equipped with the chip and a working method of the chip. 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 provide printers with printing ink to form characters or patterns that need to be printed on paper; The toner cartridge with toner is used as a consumable container to provide the printer with toner for printing to form text or patterns that need to be printed on the medium. [0003] see figure 1 , The existing ink cartridge has a housing 11, the housing 11 encloses a cavity 15, and the cavity 15 contains ink. An ink outlet 14 is provided b...

Problems solved by technology

Same as the compatible ink cartridge, the amount of toner contained in the compatible toner cartridge can also be many times the amount of toner contained in the original toner cartridge. Once the toner consumption in the toner cartridge reaches the amount of toner contained in the original toner cartridge , the remaining amount of toner recorded by the chip 23 is zero, and the laser printer cannot work normally.

[0010] Moreover, since the chip 23 also stores the serial number data of the toner cartridge, even if there is toner in the toner cartridge and the remaining amount of toner is updated to be non-zero, the laser printer cannot work normally.
