Abstract
The present invention comprises an apparatus for feeding print media, such as paper, into a printer. The paper is stored in a stack in a movable paper tray. The tray is lifted so that the top sheet of paper is brought in contact with the feed roller. The feed roller feeds the top sheet into position for printing. The tray is then backed away from the sheet which is being fed thereby minimizing the resistance on the page being fed. A unitary motor controls both the motion of the feed rollers and the movement of the paper tray. A spring serves to bias the paper tray toward the feed rollers. Thus the present invention serves to eliminate the necessity for two separate motors and prevents the feeding of the paper until after the paper tray is properly positioned.
