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.
