摘要： A paper handling apparatus 10 for an electrophotographic printer and, in particular, a desktop laser printer includes a series of paper containing trays 12, 14, 16, 18, which are configured to receive a variety of different styles and sizes of sheets of paper. The trays 12, 14, 16, 18 are individually horizontally arranged and collectively configured in a vertically stacked arrangement. A single paper feeding mechanism 20 is configured for selective operation with each of the vertically stacked trays 12, 14, 16, 18 by employing a rolamite to provide controlled vertical movement of the paper feeding mechanism 20 adjacent the vertically stacked trays 12, 14, 16, 18. The trays 12, 14, 16, 18 are selectively horizontally moveable so as to intersect the vertical path of the paper feeding mechanism, so as to allow the single paper feeding mechanism 20 to selectively engage one of the plurality of trays 12, 14, 16, 18 and sequentially remove individual sheets of paper from the selected tray 12, 14, 16, 18.
