Paper decurling is achieved at the output of a printer or other paper handling machine by discharging sequential sheets of the paper into an angled tray. Upon sensing of the paper at a predetermined height, paper curling is presumed and the tray is caused to drop. This causes the sheets to slide against an end stop and drop down with the tray. The tray then returns back upward, whereupon the sheets, which are sliding against the end stop are decurled at an end of the tray facing the discharge portion of the paper handling machine. The movement of the tray is further controlled so as to establish the stack at a uniform predetermined height at the end of each print job.
