摘要

A monitor/warranty system for electrostatographic reproducing machines (10) in which replaceable cartridges (12, 14, 16) providing a predetermined number of images are used, each cartridge having an EEPROM (90) programmed with (i) a cartridge identification number that when matched with a cartridge identification number in the machine enables machine operation, (ii) a cartridge replacement warning count, and (iii) a termination count at which the cartridge is disabled from further use, the EEPROM storing updated counts of the remaining number of images left on the cartridge after each print run.
