Abstract

A xerographic CRU (Customer Relpaceable Unit) for an electrophotographic printing machine. The xerographic CRU has retaining features and cooperates with a drive module with certain retractable features that allow the insertion and removal of the 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. An interface with a single handle assembly retracts/unlocks and extends/locks the drive module and the associated CRU subsystems into an operative position. The CRU also has electrical and drive connections for the cleaning system, the charging system and transfer/detack.
