Abstract
Method and apparatus for controlling a sheet feeder assembly for an imaging apparatus, the sheet feeder assembly including a motor coupled to a gear train for applying a rotational force to a sheet picker roller, a media supply tray for holding a media stack having a plurality of media sheets, and a buckler for buckling a top sheet of print media to separate the top sheet from the media stack, the method including the steps of driving the sheet picker roller at a initial velocity until a backlash of the gear train is eliminated and/or the top sheet has been buckled; and thereafter, accelerating the sheet picker roller from the initial velocity to a target velocity using selectable sheet picker roller velocity profiles.
