Distance Sensor Adjustment
The distance sensor is adjusted during manufacturing so you do not
need to adjust it when you install it. However, the distance sensor
must be initialized when the finisher driver board or the distance
sensor is replaced. To initialize the distance sensor:
1. Confirm that the voltage of the Lithium battery on the finisher
driver board is over 2.7 V.
2. Set the DIP switch (SW1) on the finisher driver board to 1: OFF,
2: OFF, 3: OFF, 4: ON.
3. Load a sheet of blank paper in Bins 1, 2 and 3.
4. Press the push switch (SW2) so that tray 1 moves to the initial-
ization position. When the initialization of the distance sensor is
completed, the tray assembly descends to the home position.
5. Set the DIP switch (SW1) to 1: OFF, 2: OFF, 3: OFF, 4: OFF, and
confirm that LED on the finisher driver board flashes ON for 0.5
seconds, OFF for 0.3 seconds.
