ABSTRACT:
There is disclosed an electrostatographic printing apparatus having (a) a detachable imaging module including a housing and a photosensitive member, wherein the photosensitive member is partially enclosed within the housing, and wherein the photosensitive member has an outer surface which includes an electrically conductive portion; (b) an electrically grounded component free of attachment to the module; and (c) an electrically conductive part, free of attachment to the module, in contact with both the grounded component and the conductive portion on the outer surface of the photosensitive member, thereby establishing grounding of the photosensitive member, and wherein upon removal of the imaging module the part remains in contact with the grounded component and upon insertion of a new detachable imaging module which has a new photosensitive member having an outer surface that includes an electrically conductive portion, the part contacts the electrically conductive portion on the outer surface of the new photosensitive member, thereby establishing grounding of the new photosensitive member.
