In a sheet output system with a stacking tray for a reproduction apparatus, in which sheets sequentially moving in an output path are fed out from a sheet ejection nip for stacking in the stacking tray, a sheet separating assistance unit is mounted adjacent the ejection nip with three evenly circumferentially spaced radially extending sheet separating arms, with one separating arm automatically normally extending into the output path for engagement and partial rotation and translation solely by a moving sheet lead edge in the output path, while maintaining at least one separating arm in contact with the moving sheet as the moving sheet is fed out from the sheet ejection nip to provide sheet separating assistance, even if the nip reverses for duplexing. The automatic realignment of the device to a lead edge catching position after each sheet is provided by gravity with an eccentric over-center mounting system with a large triangular shaped mounting aperture.
