Abstract
The present invention is a reproduction machine having a scanning device for projecting images of documents onto a moving photosensitive surface wherein the control of the reproduction machine is a function of the size of the copy sheets. The copy sheets are fed from a copy sheet supply into communication with a registration switch to determine the length of the copy sheet. A counter responsive to the switch converts the length of the copy sheet into a scan drive signal. The scan drive signal is used to terminate the scan drive in accordance with the length of the copy sheet.
