Abstract

Disclosed is a means to convert leftover toner images into monolayers. This results in residual lines having high mass/area being converted into monolayers having much lower mass/area. This is accomplished by spreading the mass over a larger area than originally occupied by the toner.

Disclosed is a means to convert leftover toner images into monolayers. This results in residual lines having high mass/area being converted into monolayers having much lower mass/area. This is accomplished by spreading the mass over a larger area than originally occupied by the toner.

Those skilled in cleaning and/or preclean arts will realize that the conversion may be done in either an active or passive manner using various apparatus such as a fiber strip of bristles or synthetic fur, a foam strip interfering with the photo~. receptor, slowly moving web, etc.

In the arrangment shown, a foam strip 5 is supported in rubbing contact with the surface of photoreceptor belt 6 downstream of the transfer station and upstream of belt cleaning apparatus 9. Belt cleaning apparatus 9 includes a preclean corotron 10, fadeout lamp 11. and cleaning brush 12, the latter being supported in vacuum housing 13.

Any multi-~layertoner left over on belt 6 following transfer of the developed image is effectively spread by foam strip 5 into a single layer, thereby reducing the mass/area of the leftover image toner and facilitating cleaning of photoreceptor belt 6 by cleaning apparatus 9.
