NOTE:
The values on decals 2 and 3 do not need to be input, as the machine
performs the main scan registration correction for each color during
automatic line position adjustment.
3. Print out the following test pattern (17: cross-stitch main-scan) with SP5-997.
4. Check these test patterns. If the laser beam pitch is not correct, vertical black
strips seem to appear.
•
Cross-stitch pattern: The thin lines should be of uniform thickness (no
striping effect should appear on the printout).
5. Adjust the laser beam pitch values in SP2-109-2 and -3 until the printout is
correct, as shown below.
6. Execute SP5-993-2 or “Auto Adjust” with the Maintenance menu in the user
tools.
