    Abstract: A partial reverse clutch assembly comprises a frame, a coupling member, a corrugated swing body, and a cam body. The frame mounts an input gear and an output gear, and, a coupling member that is disposed between input and output gears couple the input gear to the output gear to transmit a motorized rotational drive in a first direction. The swing body is coupled between the input gear and the coupling member and comprises a projecting swing arm. The cam body abuts and defines a sliding contact between the swing body and the coupling member, where a reversal of the motorized rotational drive oppositely rotates the output gear in engagement with the swing arm in a second direction. The cam body is displaced upon contact with the swing body during the rotation in the second direction to decouple the coupling member between the input gear and the output gear.

    Abstract: A photoconductor unit for an electrophotographic image forming device according to one example embodiment includes a housing and a photoconductive drum rotatably mounted on the housing. The photoconductive drum includes a drive coupler that is positioned to mate with a corresponding drive coupler of the image forming device to receive rotational and axial force therefrom for rotating and axially biasing the photoconductive drum when the photoconductor unit is installed in the image forming device. A wear member is positioned to receive frictional contact from a portion of the photoconductive drum in a direction of the axial bias on the photoconductive drum such that as the photoconductive drum rotates, the frictional contact on the wear member gradually wears away the wear member in the direction of the axial bias on the photoconductive drum thereby gradually shifting the photoconductive drum axially in the direction of the axial bias.

    Abstract: A photoconductor unit for an electrophotographic image forming device according to one example embodiment includes a housing and a photoconductive drum rotatably mounted on the housing. An engagement member is positioned to receive an actuation force from an actuator of the image forming device. Upon receiving the actuation force, the engagement member shifts the photoconductive drum in an axial direction relative to an axis of rotation of the photoconductive drum.
