Color Registration Errors
In addition to the SP adjustments printed on the seal attached to the LD unit, if color
registration errors occur immediately after you change the laser unit, an additional
adjustment is required.
This additional adjustment is normally not required in the field. Do it only if you see
color registration errors in test prints.
See "Color Registration Test and Error Adjustment" for instructions on how to do this
adjustment.
Skew
If skew occurs immediately after you change the laser unit, do the skew adjustment. (See
"Skew Adjustment After Laser Unit Replacement" in Section 3 of the B132/B200 Service
Manual (Venus-C1).
