Ink cartridge chip, ink cartridge, ink cartridge identification system and ink cartridge identification method

Abstract

The invention discloses an ink cartridge chip, an ink cartridge and an ink cartridge recognition system and method, and belongs to the technical field of ink-jet printing. The ink cartridge chip comprises a control unit, a chip storage unit, a chip operation unit, a chip judgment unit and a chip communication unit, wherein the chip storage unit, the chip operation unit, the chip judgment unit and the chip communication unit are electrically connected with the control unit. The chip operation unit comprises a first chip operation unit used for calculating a second algorithm check code and a second chip operation unit used for calculating a third algorithm check code. The chip judgment unit is used for comparing a first algorithm check code with the second algorithm check code; if the check codes are matched, the second chip operation unit calculates the third algorithm check code and sends the third algorithm check code and ink cartridge code table information to a printer; if the check codes are not matched, error information in the chip storage unit is sent to the printer. According to the ink cartridge chip, the ink cartridge and the ink cartridge recognition system and method, the interactive recognition of the printer and the ink cartridge can be achieved and is efficient, accurate and high in reliability; usage of illegal ink cartridges is reduced, and an ink cartridge reclaim mechanism is regulated.

Description

technical field [0001] The invention relates to the field of inkjet printing, in particular to an ink box chip, an ink box, an ink box identification system and an ink box identification method. Background technique [0002] With the popularization of office automation, printing equipment has become an indispensable equipment in office activities. Common printing equipment includes laser printing and inkjet printing. In inkjet printing, a cartridge printer and an ink cartridge installed in the printer are included. At present, there are a large number of ink cartridge consumables in the market, and there are many models, and the ink cartridge recycling mechanism is unreasonable, causing illegal ink cartridges to flood the market. On the one hand, illegal ink cartridges cause confusion to the market, on the other hand, once there are problems, ink cartridge manufacturers will shirk each other. For this reason, the printer needs to identify the printing consumables, that is,...
