Abstract

This disclosure relates to the interdocument and edge erase functions in a xerographic machine. These functions call for sharp voltage gradients to be generated on the photoreceptor. Ideally then, a light beam which is in the form of a step function is desired. The foregoing is accomplished through the use of one or more light sources 10 (Figure 1) used in conjunction with a light collimating device 12, such as a 3M "Light Control Film" to eliminate the flaring of light and thereby produce a sharp light beam.
