The risk of jams that occur during return of a cut sheet to a position inside of a cut sheet tray as the trailing edge of the sheet moves past the leading edge of the stack of sheets remaining in the cut sheet tray is reduced by having the returning sheet itself move a lever to a position over the jam area when the cut sheet is returning to the tray. The lever has a first position covering the edge of the other cut sheets and a second position removed from the edge of the other cut sheets, whereby to not interfere with sheets being fed from the stack. An abutment surface on the member is located along the sheet path to move the member between said positions by the force of a cut sheet moving along the path.
