Abstract:

A replaceable unit for an image forming device having features for aligning the replaceable unit when installed in the image forming device and to ensure alignment between the replaceable unit and a detachable unit attachable to the replaceable unit. End walls support a photoconductive drum and have a first bullet nose, second bullet nose and stop arm used for alignment of the replaceable unit in a frame of the image forming device. Support members are on a top surface of the bottom plate with a top planar surface of one of the support members forming a rotational stop and a datum surface for the detachable unit when attached. A mounting channel in one end wall provides a second datum surface for the detachable unit and a mounting channel in the other provides a deskewing plug to adjust axial alignment between the photoconductive drum and a roll in the detachable unit.

International Classification:

G03G 21/18

Abstract:

An imaging unit for an electrophotographic image forming device having positional control features for aligning the imaging unit in a supporting frame in the image forming device. The positional control features include on each end wall, first and second bullet noses and a stop arm positioned between the two bullet noses. The first and second bullet noses engage support or datum surfaces provided in corresponding openings in the frame. The stop arm receives a biasing force that rotates the imaging unit into its final operating position. A latching assembly is provided on one end wall to prevent the imaging unit from ejecting from the frame.
