Abstract
A media feeding system has a pick arm with a pick roller, a media tray, a media restrainer, a motor and a drive train. The pick arm is rotatably installed above the media tray so that it can lift the pick roller away from the media tray, and lower it onto the media tray. The media restrainer can be in an up or a down position. When in the up position, it prevents media from moving out of the media tray. When in the down position, media can move out of the media tray past the media restrainer. The drive train delivers torque from the motor to the pick arm, pick roller and media restrainer. The motor can operate in two directions. When operating in the first direction, the media restrainer moves into the down position, the pick roller lowers onto stacked media and pushes a sheet out of the media tray past the media restrainer. When the motor operates in the second direction, the media restrainer moves into the up position, and the pick arm lifts the pick roller away from the stacked media.
