Abstract

A drive module for a photoreceptor in an electrophotographic printing machine. The drive module has retractable features that allow the insertion and removal of the xerographic CRU without causing damage to the photoreceptor and other critical subsystems. The unit further has many locating members for other subsystems so that critical tolerances are maintained. A single handle assembly retracts/unlocks and extends/locks the drive module and the associated CRU subsystems into an operative position. The drive module also has electrical and drive connections for the cleaning system, the charging system and transfer/detack.
