Abstract: The automatic paper handling system of the invention which is capable of loading individual sheet (50) of a stack of paper onto a drum (59) for printing or scanning, and stacking the sheet of paper after printing or scanning, is additionally provided with duplexing capability to print or scan on the opposite side of a page of paper previously mounted to the drum without the requirement for manual reloading of the page by an operation. During unloading of the page after printing or scanning on a first side thereof a deflector (65) is interposed in the paper unloading path to cause the trailing edge of the paper during unloading to become the leading edge of the paper for a succeeding loading operation such that the side of the paper previously in contact with the drum will become the side of the paper exposed to the printing or scanning transducer.
