A first inkjet printer spit cup assembly includes a spit cup having a mounting hole and inner teeth, includes a cylindrical post attached to a base portion and positioned in the mounting hole, and includes a wing. The wing and inner teeth are adapted to permit rotation, and to prevent counter-rotation, of the spit cup about the cylindrical post. A second inkjet printer spit cup assembly includes a spit cup having a mounting hole and bottom teeth, includes a cylindrical post attached to a base portion and positioned in the mounting hole, and includes a top tooth extending from the base portion. The top tooth and bottom teeth are adapted to permit rotation, and to prevent counter-rotation, of the spit cup about the cylindrical post.

A maintenance unit for use in an ink jet printer includes a maintenance frame coupled to a printer frame, a maintenance sled moveably coupled to the maintenance frame and a spreader mechanism coupled to the maintenance sled, wherein the spreader mechanism disperses waste ink over a waste ink accumulation region as the maintenance sled moves relative to the maintenance frame.

When cover (8) of the laser printer (3) is closed, absence of the replaceable cartridge (15) or the shroud assembly (9) will activate both an electrical and a mechanical interlock. A moveable switch actuator (16) on the shroud assembly will be absent if the assembly is omitted and will not find a guide ramp (46) if the cartridge is absent, thereby assuring power to the light source remains off. A shutter (13) also blocks the normal light path and is moved aside by a pin (14) on the cartridge, and therefore blocks light unless a cartridge is installed. Walls (31) on the cartridge surround the shutter during normal use to form a protective light baffle. The laser printhead (2) is fixed within the shroud so that separation requires a necessary electrical cable (72, 74) to be disconnected.
