ABSTRACT:
An inkjet printer (10) has a movable carriage (12) supported above an ink-receiving medium by a rail (14) defining a carriage axis. A cartridge holder (16) is mounted on the carriage and having at least one cartridge compartment (18), each of the at least one compartment having a compliant compartment wall (82). Each compartment is providing with an opening at one end (19) of the carriage floor for receiving the snout (72) of an ink jet printer cartridge (20) on which is mounted a nozzle plate with more that one nozzle for depositing ink onto the ink-receiving medium. Each compartment is also provided with equalizing structure for maintaining the cartridge substantially perpendicular to the carriage axis when the compliant compartment wall is deflected by a spring at the middle of the compartment forcing two datum surfaces on the cartridge against front and rear supporting surfaces on the compartment wall. The equalizing structure preferably includes a second opening (21) at the other end of the floor.
