Adjustments after Replacing the Laser Optics Housing Unit

1. Enter SP mode.
2. Input the values printed on three decals on the new laser optics housing unit
into the following SPs. Each decal contains two values.

Decal 1
Decal 2
Decal 3

Jp:xxxxx P:46,41
600dpi
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.
