Rear Conveyor
Alignment
The rear inroad and outroad conveyors taper slightly away from the print station.
Use the following procedure to check and adjust the alignment:
1. Using a vernier above the board support plate, measure the rail width on the
print station (Dimension A).
2. Measure the rail width on the inroad conveyor close to the print station
(Dimension B). Dimension B must be between Dimension A and A plus
0.05mm.
NOTE
Ensure that the measurement is taken from the flat and not the chamfered
end.
3. Measure the rail width on the inroad conveyor close to the end of the inroad
conveyor (Dimension C). Dimension C must be between Dimension B plus
0.10mm and B plus 0.20mm.
NOTE
Ensure that the measurement is taken from the flat and not the chamfered
end.
4. If adjustment is required, loosen the board guide securing screws and adjust
the board guide to achieve the measurements above.
5. Tighten the board guide securing screws.
6. Repeat Steps 1 to 5 for the outroad conveyor.
Rail Lifted Sensor There is no adjustment on the rail lifted sensor or the vane.

Board Optos There are three board optos:
• Board at Left Sensor
• Board at Stop Sensor
• Board at Right Sensor
Positional
Adjustment
The board optos are adjustable in the X direction to compensate for any holes
or cut-outs on the product board that coincide with the sensor when the board
is in the stopped position.
With the board in the stopped position over the sensor, if the sensor is not
seeing the board due to a hole or cut-out, use the following procedure to adjust
the sensor:
1. Power down the machine.
2. Using a 2.5mm Allen key, loosen the two bolts that secure the sensor
bracket to the rails.
3. Move the sensor to the required position.
4. Tighten the two bolts that secure the sensor bracket to the rails.
5. Power up the machine and check for correct operation of the sensor.

Sensitivity
Adjustment
The sensitivity setting of the sensors is critical as it is important that the sensor
is only activated by the board and not machine parts.
To achieve an optimum setting carry out the following procedure:
1. Place a board on the rails covering the sensor.
2. Turn the sensitivity control fully anti-clockwise, ensure that the amber LED
is extinguished.
3. Re-adjust the sensitivity control clockwise until the amber LED illuminates.
NOTE
If the amber LED is flashing, this indicates a week signal. Re-adjust the
sensitivity control.
4. Remove the board from the rails and confirm that the amber LED extin-
guishes.
