Abstract

The aluminum ground plane of a layered organic photoconductor is exposed by placing an end of the photoconductor web in an enclosed scrubbing device which brushes the photoconductor's end portion as it is immersed in a solvent which dissolves the photoconductor materials, thereby exposing both surfaces of the photoconductor's ground plane.

Xerographic Photoconductor Preparation

The aluminum ground plane of a layered organic photoconductor is exposed by placing an end of the photoconductor web in an enclosed scrubbing device which brushes the photoconductor's end portion as it is immersed in a solvent which dissolves the photoconductor materials, thereby exposing both surfaces of the photoconductor's ground plane.

A typical layered photoconductor (Fig. 1) includes a thin, flexible aluminized- plastic sheet 10 upon which an adhesive layer (not shown), a charge-generating layer 11 and a charge-transport layer 12 have been coated. In a typical xerographic drum device (Fig. 2) a supply spool 13 of this photoconductor extends through a drum seal 14, around the outer surface of the drum, and reenters the drum's interior at the drum seal, to be attached to a takeup spool 15. Periodically, during copier use, a fresh supply of photoconductor is supplied to the drum's exterior surface by CCW unwinding of spool 13 as the used photoconductor portion is wound onto spool 15 by CCW rotation of that spool. In this configuration, the bottom uncoated side of aluminized substrate 10 is adjacent the drum's exterior surface, and the metal shafts of spools 13 and 15 are the means by which electrical connection is made to the photoconductor's ground plane, i.e., to the aluminum layer of substrate 10.

In order to ensure good electrical connection to this ground plane, one or both ends of the photoconductor web originally w...
