4-2. Paper Feed Tray Up and Down
Section
The paper feed tray is driven via the rack on the tray
when the pinion connected to the motor rotates.
When the paper feed tray moves up, the position of
the tray is detected with the actuator of the level
sensor and the tray stops at the detected position.
Adjustments
Adjust the position of the lower limit switch unit B to
determine the lower limit position of the paper feed
tray.
The installation hole of the lower limit switch unit B is
a slotted hole so that the position is adjusted. Fix the
lower limit switch unit B at the position as far as the
unit goes in the direction of an arrow.
Adjust the play by the rack in the up and down
directions after it has been attached to less than 1
mm (0.04") by adjusting the play by the motor unit
and motor bracket or motor bracket and frame when
attaching them.
