Patent number: 5655182Abstract: A reusable photoreceptor assembly has a gear assembly removable from a photoreceptor. A square leaf spring or ring is used to secure and remove the gear assembly to and from the photoreceptor, thereby avoiding damage to both the gear assembly and photoreceptor during the removal of the gear assembly. The undamaged gear assembly and photoreceptor may then be reused.Type: GrantFiled: June 7, 1995Date of Patent: August 5, 1997Assignee: Xerox CorporationInventors: Ismael R. Sanchez, Warren F. Brydges, Robert S. Foltz, William A. Hammond, Richard C. Petralia, Eugene A. Swain, Thong H. Vo, John K. Williams

Patent number: 5576803Abstract: An electrostatographic imaging member assembly including a hollow electrostatographic imaging drum having a first end and a second end, at least one coating on the drum extending to at least the first end of the drum, the coating having an outer electrostatographic imaging surface and a first drum supporting end cap mounted on the first end of the drum, the first drum supporting end cap including a disk shaped member having an annular skirt encircling an exterior surface of the first end of the cylindrical substrate, the annular skirt having an imaginary axis coextensive with an imaginary axis of the drum. This electrostatographic imaging member assembly may be fabricated by sliding the skirt of the end cap over the end of the drum with or without presoftening of the coating. The electrostatographic imaging member assembly may be utilized in electrostatographic imaging apparatus in which the end caps support electrostatographic imaging apparatus subassembly components.Type: GrantFiled: December 21, 1993Date of Patent: November 19, 1996Assignee: Xerox CorporationInventors: Edward C.
