DESCRIPTION OF PROGRAMS
G Manually adjusting the registration
The procedure for manually adjusting the registration is explained here.
Display "MANUAL ADJUSTMENT" as indicated in the chart on page 28, and press the [OK] key. Press the [OK] key once
again to print test pages for manual adjustment. Scales appear in the test pages that show the amount of deviation of
each of the colours C (cyan), M (magenta), and Y (yellow). When there is a significant deviation, enter the value of the
deviation to correct it.
Follow the steps below to manually adjust the registration.
Understanding the adjustment pattern
The amount of deviation is given within a range of -60 to 60, where 60 represents the maximum deviation and "0"
represents no deviation. (See the enlarged view of scale B.)
As shown below, the deviation of each colour is indicated by two scales. Scale A shows the "1's" component of the
deviation and scale B shows the "10's" component.
Adjustment pattern
The scales are printed twice for each colour, with one pair indicating the deviation in the primary scanning direction and
one pair indicating the deviation in the secondary scanning direction (C1, M1, Y1 and C2, M2, Y2).
Adjustment is performed by entering the deviations. Each deviation is obtained by adding the value of scale A and the
value of scale B. However, in most cases adjustment is possible using just the deviation value from scale A.
Follow these steps to perform adjustment.
Display "MANUAL ADJUSTMENT" as indicated
1
in the chart on page 28.

-OK?
Press the [OK] key.

Printing of the test pages begins. If you need to
cancel printing, press the [BACK/C] key.
After the test pages are printed, the display for
4
adjustment of C1 appears.
MANUAL ADJUSTMENT
C1
Press the [ ] or [ ] key until the value equal to the
5
deviation of C1 is displayed, and press the [OK] key.
G
Repeat this step to enter the deviations of M1,
Y1, C2, M2, and Y2. (When all deviations
have been entered, the display will show
"TEST PRINT.")
G
If the printed adjustment pattern is similar to the
example of C2 shown above (the peak in scale
A is between -1 and 1 and the value of scale B
overlaps "0"), correction is not necessary.

Scale B
Press the [ ] or [ ] key to select "YES" in the
6
"TEST PRINT." display and press the [OK] key.
In the adjustment pattern printed in step 6, verify
7
that the peak of the distribution in scale A is
between -1 and 1 for each colour, and that the
scale B value overlaps "0". If the patterns are
acceptable, select "YES" in the "COMPLETE"
display and press the [OK] key.
G
If the scale B values do not all overlap "0",
press the [ ] or [ ] key to select "Yes" in the
"COMPLETE" display and press the [OK] key.
Repeat steps 1 through 7.
G
For scale B values that do not overlap zero,
be sure to enter the correct the value for the
"10's" digit of the deviation.
If you need to cancel the corrections that you
8
have made and exit the program, press the
[MENU] key in the display of step 1.
