NOTE
Exiting diagnostics initialises the machine, homing the camera axes.
4. Select Back.
5. Select Shut Down.
6. Select Continue.
7. Switch the mains isolator to OFF.
8. Remove the right hand machine side panel.

10. Slacken the four timing belt clamp securing screws sufficiently to remove the
timing belt from the clamp.
NOTE
Take note of the routing of the timing belt before removing it.
11. Remove the timing belt and discard.
12. Route the replacement timing belt around the camera Y motor pulley and
the idle pulley.
13. Engage the two ends of the replacement timing belt equally into the timing
belt clamp. Tighten the timing belt clamp screws sufficiently to allow belt
movement. Ensure the timing belt is straight between the two pulleys and
the timing belt clamp.
14. Fully tighten the clamp screws.
15. Manually position the timing belt clamp on the camera Y axis timing belt so
that the distance X1 is equal to the distance X2.

16. Using a suitable cable tie, engage a forcemeter across the motor pulley.
Apply a horizontal force of 24kg to the belt. Maintaining this force, tighten
the two securing screws.
17. Remove the forcemeter. Do not remove the cable tie as further adjustment
may be necessary.
18. Ensure that the belt clamp is midway between the two pulleys.
19. Using a tension meter (Part No. 190279), check the timing belt tension either
side of the cable clamp is between 42Hz and 48Hz. Check the two readings
are within 1Hz of each other.
NOTE
Adjust the position (between the two pulleys) of the belt clamp to achieve
the 1Hz deviation.
20. If adjustment is not required, go to Step 25.
21. If adjustment is required, slacken the two securing screws as detailed in
Step 9.
22. Adjust the timing belt tension using the cable tie.
23. Tighten the locknut.
24. Repeat Steps 19 to 23 until the correct tension is achieved.
