A scanning mechanism which indicates to a user the manner of setting a page in order for the page to be properly scanned. When an automatic document feeder is not being used, a paper orientation indicator which is next to a transparent contact surface is illuminated, depending on the orientation of the input paper onto which an image is to be copied. The orientation indicator is located on a periphery of the paper support surface. The orientation indicator is located either at a corner of the transparent contact surface or centered at an edge of the transparent contact surface, depending on how the page to be scanned should be set on the transparent contact surface. Alternatively, an automatic document feeder is utilized with a copier and the automatic document feeder contains both an orientation indicator and paper position indicators which are illuminated to indicate where to place a stack of pages which are to be fed by the automatic document feeder.
