An inexpensive method for detecting paper size in an electronic printing machine is proposed and shown in the accompanying Figure. The method comprises an electric circuit that may be screened, painted, or molded onto a paper tray to indicate the size of paper loaded in the tray. The circuit layout coincides with the outline of different paper sizes as they lay in the tray.
