ABSTRACT:
A replaceable ink cartridge for an ink jet printer having an ink supply station with an ink receptacle and an electric connector. The cartridge includes a chassis removable from the ink supply station, and having an ink passage and an electrical connector connectable to the printer's electric connector. An ink reservoir is removably connected to the chassis, and has a chamber containing a supply of ink. The reservoir has an ink outlet registered with the ink passage, and the chassis has an ink level annunciator connected to the cartridge's electrical connector, for generating a signal to enable printing after the ink reservoir is depleted and replaced with a second reservoir.
