Abstract

A light-emitting diode, located outboard of a lens strip array, is focused on the edge of the photoconductive member in an electrophotographic copier to provide edge fadeout. A fiber optical device could also be used, focused on any convenient light source. In the case where fiber optics is the sole machine optics, the edge elements could be arranged in such a fashion to always receive light from the optical cavity. This would always eliminate the edge dirt problem.

A light-emitting diode, located outboard of a lens strip array, is focused on the edge of the photoconductive member in an electrophotographic copier to provide edge fadeout. A fiber optical device could also be used, focused on any convenient light source. In the case where fiber optics is the sole machine optics, the edge elements could be arranged in such a fashion to always receive light from the optical cavity. This would always eliminate the edge dirt problem.

Such a device would continuously, during the scanning operation of the copier, expose the ends or edges of the photoconductive member not used to produce images to prevent printout on the edges of the final copies.
