Lifting or lowering the paper table [D].
NOTE: 1) When the paper height sensor [E] is actuated, the top of the paper stack
contacts the pick-up roller [D], lifting it up. Then, when the paper height
sensor [E] is actuated, the table motor stops.
2) When the table lower sensor [F] is actuated, the tray has been lowered
to its lower limit, and the motor stops.
3) During a printing run, sheets are fed from the stack, lowering the pick-up
roller. When the paper height sensor [E] is de-actuated, the paper table
motor raises the paper table until the sensor is actuated again.
Paper end detection
• The paper end sensor [G] under the paper table detects when the paper on the
table runs out.
