A first simplex document is advanced to a registration position, a second simplex document is subsequently advanced to a registration position with respect to the first document, and the documents thus registered are moved simultaneously to a copying position for sequential copying, and subsequent to scanning the documents a desired number of times to produce a number of copies, are moved to an output.
