Color registration adjustment: Adjusts the start timing of
imaging for each color.
[–3 ~ 3 / 0 / 1 line/step] DFU
2 lines = 0.047566 ms (about 85 µm)
+: Delays the start timing.
–: Advances the start timing.
The start timing is adjusted only in plain paper mode,
and when one of the following conditions is satisfied:
1) Between the two images on the transfer belt (when
two images are developed on the OPC at the
same time (
2) B4 SEF or larger (multi-print job)

Adjusts the clock phase of the LD to reduce the density
difference between the left and right sides of the printout
when the color misalignment correction (SP2–952–1) is
enabled.
[0 ~ 8 / 0 / 1 /step]
Do this after installing a new laser unit; see Replacement and
Adjustment for details.
Selects either color misalignment correction or reduction
in density difference between the left and right sides of
pages.
[0 ~ 1 / 1 / 1 /step]
1: on
The data for LD1 and LD2 are switched between the left
and right sides of each page. This is done because of
the difference in the output of each LD. However, in
some cases this correction may cause density
differences between sides.
0: off
Use this setting if there are density differences between
sides.
