MX-4101N ADJUSTMENTS 5 – 96
If the color balance of each patch of the process black (CMY
mixed color) is slightly shifted to Magenta, it means that the
adjustment is proper. If the color balance of the adjustment
pattern printed in this mode is slightly shifted to Magenta, it is
converted into the natural gray color balance by the color table
in an actual copy mode. (When the color balance target is DEF
1.)

11) Use SIM 44-26 to perform the half tone image correction.
(Compulsory execution)
• Enter the SIM 44-26 mode and press [EXECUTE] key.
• [EXECUTE] key is highlighted and the operation is started.
• Enter the SIM 44-26 mode and press [EXECUTE] key.
• [EXECUTE] key is highlighted and the operation is started.
• It takes several minutes to complete the operation. After
completion of the operation, "COMPLETE" is displayed.
• After completion of the operation, the simulation is canceled.
12) Use the servicing color test chart (UKOG-0317FCZZ/UKOG-
0317FC11) in the Text/Printed Photo mode (Manual) to check
the copy color balance and density. (Refer to the item of the
copy color balance and density check.)
If the copy color balance and density are not satisfactory, per-
form the following procedures.
the copy color balance and density. (Refer to the item of the
copy color balance and density check.)
If the copy color balance and density are not satisfactory, per-
form the following procedures.
13) Execute the initial setting of the half tone image correction.
(SIM 44-21)
14) Execute the half tone image correction. (Forcible execution)
(SIM44-26)
15) Use the servicing color test chart (UKOG-0317FCZZ/UKOG-
0317FC11) in the Text/Printed Photo mode (Manual) to check
the copy color balance/density. (Refer to the item of the copy
color balance/density check.)
the copy color balance/density. (Refer to the item of the copy
color balance/density check.)
Though the procedures 13) - 15) are performed, the copy color
balance and density are not in the specified range, there may
be another cause.
Troubleshoot the cause and repair or perform proper treat-
ments, and try all the procedures of the print image adjustment
from the beginning.
If the automatic adjustment cannot obtain satisfactory results
of the copy color balance and density, use SIM 46-21 (ADJ
20C) (Manual adjustment).

16) Check the printer color balance and density.
There are two methods to check the color balance and density.
(Method 1)
Use SIM 64-5 to print the print test pattern and check the print
color balance and the density.
Set each setting value to the default and press [EXECUTE]
key, and the print test pattern is printed.
(Refer to the item of the printer color balance and density
check.)
(Method 2)
Use SIM67-25 to print the color balance adjustment sheet and
compare the black patch color balance of each process (CMY)
with the black patch. This procedure allows checking the color
balance adjustment result correctly.

If the color balance of each patch of the process black (CMY
mixed color) is slightly shifted to Magenta, it means that the
adjustment is proper. If the color balance of the adjustment
pattern printed in this mode is slightly shifted to Magenta, it is
converted into the natural gray color balance by the color table
in an actual printer mode. (When the color balance target is
DEF 1.)
If a satisfactory result on the print color balance and the den-
sity is not obtained with the automatic adjustment, execute the
manual adjustment (SIM 67-25) (ADJ 21B).

a. General
This adjustment is used to adjust the color balance and the density
in the monochrome mode, the heave paper mode, 1200dpi, 600dpi,
and 1bit mode.
This simulation is used to improve image quality in these modes
and images.
