G Manually adjusting the registration
The procedure for manually adjusting the registration is explained here. This procedure is used when you select manual
adjustment in the [Registration adjustment] key operator program explained on page 10.
Touch the [MANUAL ADJUSTMENT] key and then the [EXECUTE] key to print the adjustment pattern for manual
registration adjustment. This pattern consists of scales that show how much each of the colours C (cyan), M (magenta),
and Y (yellow) are off. If a colour deviates greatly from the reference value, it can be corrected by entering the deviation
value from the touch panel. 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 value and "0" represents
minimal deviation. (See the enlarged view of scale B.)
As shown in the diagrams, the scales indicating the range of deviation appear in pairs for each colour, with one scale
showing the x1 component of the deviation, and the other scale showing the x10 component.
Adjustment pattern
Scale A consists of two scales for each colour (C1, M1, Y1 and C2, M2, Y2), and the peak value of the distribution range
of each colour on the scale is the x1 component of the deviation.
Adjustment is performed by entering the deviation, which is the total value of scale A and scale B. However, in most cases
adjustment is possible using just the deviation value from scale A. Follow these steps to perform adjustment.
1
In the manual registration adjustment screen
of the touch panel, touch the key of the colour
you wish to correct ([C1], [M1], [Y1], [C2], [M2],
or [Y2] key).
C1 M1
0 0
C2 M2
0 0
2
Use the or key to enter the scale A (x1)
value of the key selected in step 1.
C1 M1
5 0
C2 M2
0 0
G Repeat steps 1 and 2 to adjust the other colours.
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.

To print an adjustment pattern showing the
results of your entries, touch the [PRINT] key.

4 In the adjustment pattern printed in step 3,
verify 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
this is the case for all colours, respond to
the display messages by touching the
[YES] key and end adjustment.
G If the scale B value of one (or more) of the
colours does not overlap "0", touch the [NO] key
to return to the screen of step 1.
G If a scale B value of a colour does not overlap "0",
the value overlaps 20, 40, 60, -20, -40, or -60 as
shown above. In step 2, enter the number that
the value overlaps as a multiple of 10.
5 Repeat steps 1
adjustment.
G You can touch the [OK] key at any time during
the adjustment
correction values entered to that point and end
manual registration.
G To cancel all corrections entered to that point
and return to the previous screen (before
manual registration was executed), touch the
[CANCEL] key.
