3. Secure the sensor in position with the two mounting screws.
4. Power up and run the machine, checking for correct operation of the sensor.
5. If coarse adjustment of the sensor position is required, this can be achieved
adjusting the position of the sensor mounting bracket by use of the inboard
sensor bracket mounting holes.
Sensitivity
Adjustment
The auxiliary conveyors are a diffuse sensor type. The sensor switching
threshold can be adjusted by means of a sensitivity control switch mounted on
the face of the sensor. This ensures that when a board is fed into the machine
(via transport belts) the sensor output switches to ON.
To achieve an optimum setting carry out the following:

1. Place a board on the rails covering the sensor.
2. Turn the sensitivity control on the face of the sensor fully anti-clockwise,
ensure the green and red LED is extinguished.
3. Re-adjust the sensitivity control clockwise until both LEDs illuminate. Con-
tinue rotating the sensitivity control one more graduration clockwise.
4. Remove the board from the rails and confirm that both LEDs are extin-
guished.
5. Remove the board. Repeat Step 1 and confirm that both LEDs illuminate.

WARNING
BOARD CLAMPS. EXTREME CARE MUST BE EXERCISED WHEN WORKING IN
THE TOOLING AREA OF THE MACHINE TO AVOID INJURY. THE FOILS ON THE
FRONT AND REAR BOARD CLAMPS ARE VERY SHARP.
Positonal
Adjustment
If heavy boards are being printed and causing damage to the conveyor board
stops, adjustment of the position of the sensor can be carried out to minimise
this effect. To adjust the position of the sensor carry out the following:
1. Power down the machine.
2. Loosen sensor mounting bracket bolts. Adjust the position of the mounting

bracket.
3. Tighten the securing bolts.
4. Power up and run the machine, checking for correct operation of the sensor.
5. If coarse adjustment of the sensor is required, a further bracket mounting
hole is available inboard.
Sensitivity
Adjustment
The print station Board at Left/Right sensors are a background suppression
sensor type. The sensor switching threshold can be adjusted by means of a
sensitivity control switch mounted on the face of the sensor. This ensures that
when a board is fed into the machine (via transport belts) the sensor output
switches to ON.
