Abstract: A media pass through configuration for printers in which media is fed from superimposed and removable media holders, such as trays, through a media path to a print engine. A rack disposed in either the frame of the printer or other modular and stackable media option, is dimensioned for receiving at least one media carrying, removable tray disposed beneath the print engine. A door, hinge and latch combination, the hinge connected intermediate the door and either the frame of the printer or the frame of the modular option so that the door opens in a plane swingable substantially about one longitudinally extending edge of the media path to the print engine, and outwardly and away from the front of the tray. The latch is positioned remotely from the hinge for moveably attaching the door to the printer in a position confronting the tray when the door is in a closed or first position, and open for facilitating tray removal when the door is in an open or second position.

Abstract: Two stacked paper trays (43, 45) are connected electrically by cable (53) and are physically combined, as by bolts. The combined unit has a single microprocessor (49). The paper trays communicate status, such as paper size and paper amount to the microprocessor. The microprocessor reports upon interrogation from a control processor (61) of a printer (7) that it is a multiple tray unit and reports the status for each unit. This avoids the use of a microprocessor with each tray.
