ABSTRACT:
A document registration system is disclosed which enables documents of various sizes to be registered at different corner registration positions on a platen and to be projected onto a photoreceptor so that the projected images have one side aligned along a common edge parallel to the edge of the photoreceptor. A lens drive and control circuit is provided for determining lens position, comparing it with a home position and moving the lens to a new position associated with the particular registration and magnification.
