3.4.7 LASER BEAM PITCH ADJUSTMENT [ALL MODELS]
1. Print out the following test patterns – cross-stitch pattern and two-dot argyle
pattern.
•
Select the test pattern with SP 2902.
•
After selecting a pattern, the display automatically goes to SP 5902. Use SP
5902-1 to print one test pattern.
•
After completing the adjustment, reset SP 2902 to ‘no specified’.
2. Check these test patterns. If the laser beam pitch is not correct, the images are
as follows.
•
Cross-stitch pattern: Vertical black strips seem to appear.
•
Argyle pattern: The density of the diagonal lines is light or the lines have
disappeared.
3. Adjust the LD unit holder position: Tighten or loosen the screw [C] (see the
previous page) until the printout appears as follows.
• Cross-stitch pattern: The thin lines are of uniform thickness (no striping effect
should appear on the printout).
• Grid pattern: The diagonal lines appear clearly and are of normal density.
