21. Ensure that the belt clamp is midway between the two pulleys.
22. Using a tension meter (Part No. 190279), check the timing belt tension either
side of the cable clamp is between 52Hz and 58Hz. 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.
23. If adjustment is not required, go to Step 28.
24. If adjustment is required, slacken the idle pulley locknut as detailed in
Step 11.
25. Adjust the timing belt tension using the cable tie.
26. Tighten the locknut.
27. Repeat Steps 22 to 26 until the correct tension is achieved.
28. Remove the timing belt clamp securing screws one at a time, apply a
suitable locking compound and fully tighten.
29. Remove the cable tie.
30. Refit the panels removed in Step 10.
31. Power up the machine and press the System button to initialise.

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.
