Abstract
A roller assembly for a single sheet feeder includes a stack damper which is rotatably suspended on or near a pre-feed roller axis to prevent buckling of thin media sheets and to impart a slight bend to thick media sheets during sheet movement by the pre-feed roller. The stack damper has a surface which extends from a location proximate the pre-feed roller parallel to the surface of a stack of media from which individual sheets are to be removed.
