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.
Board at Left/Right Optos
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.
Positional
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.
To achieve an optimum setting carry out the following procedure:

NOTE
Ensure Camera X Axis Parallelism (Camera and Vision Systems Module
Chapter refers) has been carried out prior to commencing this procedure.
1. In Camera Diagnostics, home the Camera X and Y axes. Select Drive to
Board Stop Position the camera carriage is driven to the rear of the front
rail.
2. Raise the printhead and insert the head prop.
3. Select Close System to power down the machine.
4. Carry out either of the following:
a. Remove the camera (refer to Camera and Vision Systems Module Chap-
ter, Camera and Optical Unit Assembly Removal).
b. If available fit a spare camera assembly bearing to the right hand end of
the camera rail.
