Abstract
A document reproduction machine, such as an electrostatic copier, has a copy station with a front reference edge for operator convenience. A reproduction station adjacent the copy station reverses the image such that the reference edge is at a rear or remote position from the operator. The duplicate copy is initially referenced to the rear reference edge. An aligner in a transfer station moves the duplicate copy to a front reference edge and into an exit station which may include a collator. In a minimal transport distance, documents of various lengths are automatically handled and aligned by the apparatus.
