Abstract

See full text

There is disclosed an exposure unit and method of operation having advantage of deformable mirror device (DMD) technology. The exposure unit is used to provide front end image processing for a xerographic process printing system. The unit, in one embodiment, is constructed as a unitary member having a lamp socket, a support for holding a flat DMD substrate, a set of light focusing lenses, an image focusing lens, a light baffle and an extra light trap chamber. The unit is separated from the xerographic drum by a solid base which contains a slot positioned so that the image from the image lens passes therethrough for supplying the image to the drum. The light bundle is directed to the xerographic drum location along an optical path formed by a system of fold mirrors in the lower body of the unitary member.
