September 2006 PAPER LIFT
B473-13
Peripherals
Pressing the tray down button [A] reverses the rotation of the tray motor [B] and
lowers the tray [C].
The tray lowers until the stack sensor [D] detects the top of the stack and stops the
tray motor.
• T his mechanism lowers the tray by 5 cm, which gives the us e r enough space to
add 500 sheets of paper.
• If the down switch is then pressed again, the bottom plate moves down once
again by 5 cm. This allows the customer to replenish paper in convenient
amounts and at the same position.
A lower limit sensor [E] (triggered by an actuator on the bottom of the tray) is also
provided to stop the tray motor if the stack sensor should fail.
