ABSTRACT:
A full-frame flash illumination and imaging system is disclosed wherein an optical component located in the floor of the light housing compensates for unwanted charge variations on a photoreceptor belt caused by reflections of the lens from the document platen. The area of the belt upon which a negative lens image is formed is predetermined and a controlled quantity of light is directed towards this area, using light generated in the housing during exposure, to reduce the charge level of the area to the degree necessary to compensate for the negative lens image. Several optical components useful for this purpose are disclosed including a light pipe and a second projection lens.
