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.
