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.

Abstract: A replaceable unit for an electrophotographic image forming device includes a housing having a photoconductive drum rotatably mounted thereon. The photoconductive drum has a rotational axis. A guide channel on an exterior of the housing extends parallel to the rotational axis of the photoconductive drum and is positioned to guide insertion of the housing into the image forming device. A positioning stop on the housing is movable between a latching position and an unlatching position. In the latching position the positioning stop obstructs at least a portion of the guide channel to limit the travel of the replaceable unit in the image forming device parallel to the rotational axis of the photoconductive drum. A release handle on the housing is operatively connected to the positioning stop to move the positioning stop from the latching position of the positioning stop to the unlatching position of the positioning stop.

Abstract: An assembly for an electrophotographic image forming device according to one example embodiment includes a charge roll and a bracket that extends along an axial length of the charge roll. First and second bearing retainers are positioned on a first axial end and a second axial end of the bracket, respectively. First and second bearings are pivotally mounted to the first and second bearing retainers, respectively. Each of the first and second bearings has a charge roll opening that supports a respective axial end of a shaft of the charge roll. First and second biasing members act on the first and second bearings, respectively. The first and second biasing members bias the charge roll toward an operative position for charging a photoconductive drum. A direction of force from the first biasing member on the first bearing and from the second biasing member on the second bearing is toward the bracket.

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.

Abstract: A deskewing plug and assembly mountable in a frame having a first and a second shaft forming a nip therebetween with the second shaft rotatably mounted in a pair of opposed channels and biased toward the first shaft for adjusting the axial alignment of the shafts. The deskewing plug has a generally cylindrical body having first portion, a second portion and a tab portion. The second portion has a circumferential camming surface cooperatively engageable with the second shaft. Rotation of the plug and camming surface adjusts the axial alignment of the second shaft. The tab portion radially extends from the first portion and has radially extending ridges frictionally engageable with a wall of the opening in the frame to prevent rotation of the deskewing plug after adjustment. A cap may be provided to cover and frictionally engage the tab with the cap being fastenable to the frame.
