Elevator Sequence
The wire drum rotates by the elevator motor as the wire drum rolls
the wire pulling the hook plate up and down. The lower tray moves
up by the driving force of the elevator motor until the elevator upper
limit sensor is ON, the paper feeds onto the Tray, or until the paper
upper level sensor B is ON if no paper feeds onto the Tray. When
paper feeds out to the lower tray and the paper full sensor A turns
ON, the lower tray moves down until the paper full sensor A turns
OFF. If paper feeds onto the lower tray when the elevator lower limit
sensor turns ON, and the paper upper level sensor B turns ON,
paper feeding from host printer is prohibited. When paper is
removed from the lower tray and the paper upper level sensor B
turns OFF, the lower tray moves up.
