Abstract
A cartridge identification system for identifying a characteristic of a cartridge inserted in a printer. The cartridge identification system comprises an identification circuit which is triggered by an electrical connection between a printed circuit board coupled to the cartridge and a plurality of spring contacts in a cartridge receptacle in the printer. An electrical logic signal is read by an internal processing unit, which determines a characteristic of the cartridge based on the logic signal.
