A finisher for stacking and stapling, or binding, sheets of paper from printers and the like. The finisher accommodates two sizes of paper, one frequently being twice the size of the other. Staples are positioned in the smaller size papper along an edge and in the larger size in the middle of the sheets. Two fixed position gates are controlled to stop the paper sheets at one of two positions for alignment and stapling. Once stapled, the sheet sets are gripped, turned over, and deposited on elevator-type stacking trays. For the shorter sheet sets, the trays move independntly. For the larger sheet sets, the trays move togehter.
