6.13.3 TRAY AND PAPER LIFT MECHANISM – TRAY 2,3
Bottom Plate Lift
Tray lift operates in this order:
[A]: Tray lift motor switches on
[B]: Coupling rotates
[C]: Pin locks coupling at shaft
[D]: Shaft rotates
[E]: Lift arm raised by the rotation of the shaft
[F]: Bottom plate pushed up by lift arm
NOTE: The universal trays (Tray 2, Tray 3) each have a paper near end sensor
inside the lift motor assembly. The sensor measures the angle of the lift
shaft. There are four possible readings from this sensor, to indicate four
