Abstract
An electrophotographic printing system incorporates two sets of moving optical components, one on each side of a projection lens. A document on a platen is scanned by a first set of moving mirrors with the scanned image projected by a lens towards a photoreceptor. A second set of moving mirrors precesses the image onto the photoreceptor. In one embodiment, a drive system commonly drives both the object side and the image side mirrors to provide the required document scan and precess motions. In a second embodiment, the image side system is driven as a function of the photoreceptor (process) speed.
