Abstract

In electrophotographic devices, a build up of residue on the photoreceptor surface may be noted over time. The build up may be comprised of various contaminates such as paper, fuser oil, toner, etc. commonly referred to as toner film. Once adhering, these contaminates cannot be removed from the photoreceptor by cleaning systems directed to the removal of loose toner.

Proposed Classification

In electrophotographic devices, a build up of residue on the photoreceptor surface may be noted over time. The build up may be comprised of various contaminates such as paper, fuser oil, toner, etc. commonly referred to as toner film. Once adhering, these contaminates cannot be removed from the photoreceptor by cleaning systems directed to the removal of loose toner.

Proposed are a number of methods of abrading the photoreceptor in a manner for removal of toner film without damaging the photoreceptor.

Foam Abraders: A foam roller may be slowly rotated against the photoreceptor, either continuously or intermittently for the removal of contaminant. Toner collects in the foam pores to abrade the photoreceptor surface for the removal of toner film as the roll rotates. Desirably, the roll is located downstream from the cleaner to avoid contamination with toner. If it is found desirable to rotate the roll against the photoreceptor only inter- mittently, a D-shaped roll may be provided, which periodically will bring an abrading surface into contact with the photoreceptor surface. Alternatively, a simple foam pad may be periodically brought into contact with the surface to the same purpose.

Web/Scroller Cleaner: A web abrader may be provided with a long flexible web extending between pickup and storage rolls in abrading contact with a photoreceptor surface. When brought into a cleaning position, the web may be either slowly moving against the direction of photoreceptor surface travel or stationary. Against...
