ABSTRACT:
A sheet feeder (20) and method of operation thereof feeds sheets in a conveyance direction (30). The sheet feeder (20) comprises a sheet hopper (22); a sheet deflector (24); and a sheet extractor (26). The sheet deflector (24) is arranged for deflecting a top sheet-to-be-fed (32) from a sheet stack (28) from a sheet undeflected acquisition position to a sheet deflected position. The sheet deflector (24) has a major axis (34) oriented essentially parallel to a trailing edge the top sheet-to-be-fed from the sheet stack (28). The sheet deflector (24) is arranged to undergo three degrees of motion including selective rotation about its major axis for moving the top sheet-to-be-fed from the sheet undeflected acquisition position to the sheet deflected position.
