Apparatus for producing sets of copies from a set of document sheets, some of which can be produced in a collating mode by means of a recirculating feeder and others cannot be produced in a collating mode. The copies that are produced in a noncollating mode are stored temporarily. Programmable means control the making of copies in a collating mode and the delivery of copies temporarily stored so that the copies arrive at a receiver or finisher in collated sets of copies with the page order of the copy sets corresponding to the page order of the document set.
