ABSTRACT:
An electrophotographic copying apparatus is disclosed having an imaging system for selectively shifting an image on an output copy sheet in response to a particular image shift selection by a operator. Electronic input signals, representative of selective image position, are transmitted to a system control circuit via a user interface device which, in turn, generates a signal for transmission to a lens drive circuit. The lens positions the image at the appropriate location on the photoreceptor so as to properly position the output image on the output copy sheet in accordance with the selected image shift. An algorithm is provided for determining the appropriate lens position relative to its "home" position and for accomplishing required lens movement.
