Abstract

Some xerographic drums are fabricated from moderately heavy-wall aluminum tubing and in production are manufactured to a predetermined size and coated with photosensitive layers. Due to the cost of the tubing, drums are reclaimed after being returned from the field. The surface layer is stripped and the tube mechanically expanded slightly to permit remachining of the surface in preparation for recoating. When the tubing can no longer be reclaimed it is discarded.

METHOD AND APPARATUS FOR MOUNTING PHOTORECEPTOR SLEEVES (Cont'd)

Some xerographic drums are fabricated from moderately heavy-wall aluminum tubing and in production are manufactured to a predetermined size and coated with photosensitive layers. Due to the cost of the tubing, drums are reclaimed after being returned from the field. The surface layer is stripped and the tube mechanically expanded slightly to permit remachining of the surface in preparation for recoating. When the tubing can no longer be reclaimed it is discarded.

A more recent approach in copiers replaces the removable drum with a permanent precision cylinder having a thin nickle sleeve on which the photosensitive surface is deposited. The sleeve is replaced with a new one when it is no longer satisfactory. If the sleeve is returned from the field, its components can be reclaimed chemically thereby including advantages over other xerographic drums of 1) having a permanent cylindrical member that is designed and fabricated to run in a copier with much less drum run-out than is possible with drum assemblies that have to be reassembled in the field; 2) materials being of relatively low cost and reclaimable; and 3) shipping costs being much less because of the lower weight.

In order to meet the requirements of mounting these sleeves so that they are easily replaced and are supported so that they are essentially rigid and run true when mounted, a method and apparatus for mounting the sleeves is shown in Figures 1 through 4. of the drawings. This disclosure is designed to replace complicated mechanical fixtures that expand t...
