Abstract
The present invention is directed towards an optical scanning system for an electrophotograhic printing machine wherein a lens control system is provided to enable lens movement independent of lens movement which occurs during magnification changes. The lens carriage is adapted to be independently driven in one or two directions dependent on the mode of operation selected by the operator and under the control of a system controller which analyzes the inputs which determine lens position (open platen or document feeder mode, output copy size, magnification).
