29. Secure the jig to the front rail using the two jig to rail thumbscrews.
30. Secure the jig to the rising table using the two jig to table thumbscrews.
31. Check that the location pins are up against the front edge of the manual
tooling plate using a 0.05mm feeler gauge, as in Step 28.
32. Using feeler gauges check that the gap between both alignment pads and
the belt support plate of the front rail is 0.25mm ±0.05mm.
33. If adjustment is necessary refer to the Transport Rails Module chapter -
Adjustments and Settings - Front Rail Parallelism.

34. Bring the camera carriage X axis support platform into contact with the
camera alignment pins.
35. Look for a gap between the camera alignment pins and the linear bearing
on the front edge of the camera X axis support platform, if no gap exists
adjustment is unnecessary. Continue from Step 48.
36. If a gap exists, carefully attempt to insert a 0.25mm shim between the
alignment pin and the linear bearing on the front edge of the camera X axis
support platform. If the shim cannot be fitted the gap is less than 0.25mm
and adjustment is unnecessary. Continue from Step 48.
37. If a gap exists which is greater than 0.25mm adjustment is necessary.
38. For machines with rotary motors continue with Step 39. For machines with
linear motors go to Step 44.
