Write down the displayed skew level. 
(Meaning of the skew level value and the adjustment proce-

* If "OK" is displayed for all items of C, M, and Y (SKEW),
there is no need to perform the adjustment.
* When "R" is displayed at the head of the value, turn the LSU 
skew adjustment screw clockwise.
* When "L" is displayed at the head of the value, turn the LSU 
skew adjustment screw counterclockwise.
* The turning amount of the adjustment screw corresponds to 
each adjustment value. C, M, and Y indicate numbers of
clicks.
The display value is rounded at the decimal point.
* "C, M, and Y(SKEW)" shows the number of adjustment click 
steps for each adjustment screw of C, M, and Y.

MIAN, SUB: Difference from the previous adjustment value of
image registration.
Example: 
If 105 for this time and 103 for the previous time,

SKEW: Judgment of the LSU skew adjustment result. OK or
NG.
PHASE: OPC drum phase adjustment value of the previous
time

Repeat the procedures 2) to 4) again, and check to confirm
that C, M, and Y (SKEW) are OK.
If any of them is NG, turn the LSU skew adjustment screw of
the corresponding color to adjust.
NOTE: When an abnormality occurs, "ERROR" is displayed.
In this case, check each drive section and the process sec-
