When fitted to the machine rails the diffuse sensors switching threshold can be
adjusted by means of a sensitivity control switch. This ensures that when a board
is fed into the machine (via the transport belts), the sensor output switches to ON.
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 green LED
is extinguished.
3. Re-adjust the sensitivity control clockwise until the green LED illuminates.
4. Remove the board from the rails and confirm that the green LED extin-
guishes and the red LED illuminates.
5. Turn the board 90° and position back onto the rail system (so that the board
lies on top of the rail system as shown in the figure below). Confirm that the
red and green LED’s are extinguished. (If the green LED illuminates, turn
the sensitivity control anti-clockwise until the green LED extinguishes.)
6. Remove the board. Position the board back on the rail system, as in Step 1,
and confirm that the green LED illuminates. Carry out Step 4.

Front Rail Parallelism
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.
NOTE
Ensure Camera X Axis Parallelism (Camera and Vision Systems Module Chap-
ter 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 Chapter,
Camera and Optical Unit Assembly Removal).
b. If available fit a spare camera assembly bearing to the right hand end of
the camera rail.
5. Fit a Dial Test Indicator (D.T.I.) to the camera carriage bearing.
6. Using the D.T.I. check the front rail parallelism to camera carriage rail over
the length of the 'O' ring support plate to ±0.2mm.

7. If adjustment is necessary, carry out the following:
a. Slacken the four rail securing bolts (two each side) adjust the front rail as
required. Tighten the bolts, re-check the parallelism.
b. When the adjustment is complete, remove each bolt disturbed (one at a
time), apply suitable locking compound and fully tighten. Remove the
D.T.I.
8. Carry out either of the following:
a. Refit the camera (see Camera and Vision Systems Module Chapter, Cam-
era Refitment).
b. Remove the spare camera bearing from camera rail.
9. Switch on the machine remove the head prop and lower the head. Initialize,
carry out the Home Position Rail Width Check and Camera Reference
Position (see Rail System Module Chapter and Camera and Vision Systems
Module Chapter).
Rear Rail Parallelism
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.
NOTE
Ensure Camera X Axis and Front Rail Parallelism (see Camera and Vision
Systems Module Chapter and Rail System Module Chapter) has been carried out
prior to commencing this procedure.
1. In Rail System Diagnostics, select Adjust and alter board width to 250mm.
2. Select Drive Rail to Board Width. The rails are driven to the board width
selected.
