Abstract
An improved sheet separator and guide construction for a printer having a supply station and a feeder/platen for feeding a top sheet from a supported sheet stack and transporting it through the printing region. The construction includes a force plate for urging a supported sheet stack so that its top sheet contacts the feeder-platen and is moved toward a supply station egress region. A pair of sheet corner deflectors located respectively at opposite edges of the supply station egress region are constructed to direct sheet corners fed there-against inwardly toward the sheet center, and a central deflector located along a central portion of the egress region in spaced relation between the corner deflectors is constructed to direct the center lead-edge of a sheet fed there-against upwardly toward the printer top.
