Abstract
Abstract An illumination system includes a platen upon which a document rests. The document is irradiated directly by light from a light source and indirectly by light reflected from an opposing reflector. The light reflected from the document passes through an opening or slit in the illumination registration device. The opposing reflector and light source are attached to an illumination system registration device. The illumination system registration device includes an opposing reflector locating surface and a lamp locating feature for providing proper registration and alignment between the light source and the opposing reflector. The opposing reflector locating surface is shaped in the same shape as the opposing reflector.
