ABSTRACT:
Systems and methods for feeding media into a printing system in which a movable media guide is used to register media on a tray with a potentiometer and an opto-interrupt sensor are mounted in a fixed position relative to the tray with the slidable potentiometer member being moved by translation of the media guide. An obstruction structure is coupled to move relative to the opto-interrupt sensor when the media guide is translated and provides one or more fins to selectively block or open the optical signal path of the opto-interrupt sensor, with the sensed media width being determined according to the output signals of the opto-interrupt sensor and the potentiometer.
