Abstract
A printhead cartridge identification system is disclosed which ensures that an ink jet printer operates only with ink jet cartridges compatible with the specific printer function. An ink container which supplies ink to an associated printhead has a light reflector incorporated into a transparent wall of the ink container housing. The cartridge, comprising the ink container and associated printhead, is mounted on a scan carriage. Periodically, the carriage is conveyed to an optical station comprising a light source and a photosensor. The light source is energized and a beam of light is directed towards the reflector.
