Imaging system with a plurality of document registration positions.

摘要

A document registration system is disclosed which enables documents of various sizes to be registered at different corner registration positions on a platen (34) and to be projected by a lens (42) onto a photoreceptor (10) so that the projected images have one side aligned along a common edge parallel to the edge of the photoreceptor. Lens drive and control circuits (50,54) are provided for determining the lens position, comparing it with a home position and moving the lens to an new position associated with the particular registration and magnification.
