Abstract
In a system of plurally recirculating a set of document sheets for precollated copying wherein the document sheets are repeatedly individually fed seriatim from the bottom of an overlying stack thereof for copying with registration and returned to the top of the stack for restacking in a tray having a support surface, a rear guide and two edge guides, an improvement is disclosed that includes a straight ramp attached to one of the edge guides so that document sheets returned to the support surface will lie flat against the edge guide and thereby provide a positive registration position along the junction between the ramp and the rear guide thereby reducing the possibility of mis-registration due to bending of the document sheets during feeding and recirculation.
