Abstract

In conventional copy machines, the photoreceptor in one xerographic cycle goes through the following stations: charging, image exposure, development, transfer, cleaning and erase. Between the exposure and the cleaning station, the photo-receptor is usually exposed to other corotrons which are necessary for various machine functions. An example is the AC preclean corotron. When an insulating overcoating is used on top of the photoreceptor surface, the presence of a corotron before the erase can cause severe ghosting. This ghosting can be eliminated by exposing the photoreceptor, after development, to an erase lamp before it is exposed to corotrons.
