Adjustments After Laser Unit Replacement

SP Adjustments
[A]
1. SP codes are written on an A5 sheet provided with the laser unit. These SP
codes must be done after the laser unit is replaced.
SP2154 001 (K)
SP2154 002 (M)
SP2154 003 (C)
SP2154 004 (Y)
Only the settings shown with the first barcode [A] (2-Point Target) are
necessary. The other information on the sheet can be ignored.
NOTE: Enter the values printed on the A5 sheet. Do not enter the values
shown in the sample above.
2. Make a test copy ( 3.19.4)
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" in section 3.19.4 for
instructions on how to do this adjustment.
Skew
If skew occurs immediately after you change the laser unit, do the "Skew
Adjustment" in section 3.19.5.
