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:

1. Place a board on the rails covering the sensor.

2. Turn the sensitivity control fully anti-clockwise, ensure that the LED is

extinguished.

3. Re-adjust the sensitivity control clockwise until the LED illuminates. Con-

tinue turning the sensitivity control clockwise for one more graduation.

4. Remove the board from the rails and confirm that the LED extinguishes.

Print Station 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.
