the air gap between the forcer and the magnet track is equal on both the left
and right side of the forcer.
19. Manually move the camera to the right hand side of the machine and repeat
Step 18 for the right hand end of the magnet track.
20. If the alignment is correct, go to Step 24.

screws. Slacken the screws but do not remove. Gently move the bracket
in the direction required for the 0.5mm shim to fit comfortably all around.
Tighten the screws to secure.
22. Check the air gap again to ensure that the screws have all been tightened
evenly without misaligned the forcer.
23. Slide the camera assembly along the whole length of the X camera axis and
ensure there are no points where the forcer contacts the magnet track side
wall.
24. Refit the left side panel.
Y Axis 25. Remove the right side panel.
26. Manually move the camera support beam to a central position where access
to the unit can be readily gained.

Vision Height for Standard and MTR Rail Systems
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 the board file used has the correct board thickness value. Check rail /
camera X motor bracket clearance. Remember that the vision height may be
higher if a thinner board is used.
1. Select Unload Screen.
2. Open the front printhead cover.
3. Remove the stencil from the machine.
4. Place the board on the rails and slide to a central position.
5. Refit the stencil.
6. Close the front printhead cover.
7. Press the System button.

14. Select Run Diagnost.
15. Remove the left hand safety cover.
16. For exceptions, refer to the note below. Using a suitable metric rule,
measure the distance between the bottom of the stencil to the top of the
board. Check that the dimension is 78mm -0.0mm / +0.2mm, (ie the height
cannot be less than 78.0mm).
NOTE
For MTR and OTS transport rail systems, the vision height setting is set as
above, but the measurement is 79.5mm.
17. If the dimension is correct, go to Step 26.
18. Use Next or Previous to highlight Drive Table Using Jog Buttons.
