SYSTEMS, METHODS AND APPARATUSES FOR AUTHORIZED USE AND REFILL OF A PRINTER CARTRIDGE

摘要

The systems, methods and apparatuses described herein provide a chip for a cartridge with dispensable material may be provided. In one aspect, the chip may comprise a non-volatile memory for storing a number tracking amount of dispensable material in the cartridge, a circuit with permanently and irreversibly changeable state and circuit components configured to receive and process a first message, and receive a second message. The first message may comprise a first command and an operation input value for a print job at the cartridge, and to process the first message may comprise decreasing the amount of dispensable material. The second message may comprise a second command to increase the amount of dispensable material. The circuit components may be further configured to ignore the second command if the circuit has permanently and irreversibly changed its state to prevent responding to requests to increase the number tracking amount of dispensable material.
