MX-4070N  ADJUSTMENTS AND SETTINGS  5 – 35

• Factory target in the copy color balance adjustment (SIM 46-74/46-24)

By use of SIM 63-11, one of the following color balances can be set as the factory color balance target.
Each of the three color balances cannot be changed. (Fixed)

• Service color balance target in the copy color balance adjust-

ment ((Automatic adjustment) SIM 46-74/46-24).
For the service color balance target, an optional color balance
can be adjusted with SIM 46-21 and registered with SIM 63-7.
When, however, SIM 63-8 is executed, the color balance is set to
the same balance as the factory color balance target set with
SIM 63-11.

• Color balance target in the user color balance adjustment

This color balance is same as the service color balance target in
the copy color balance adjustment (Automatic adjustment) (SIM
46-74/46-24). When, therefore, the service color balance target
is changed, this target is also changed accordingly.

(Meaning of the service color balance target gamma data and the
purpose of registration)
This procedure must be executed only when the color balance is
customized with SIM 46-21.

If the color balance is not customized, this procedure is not
required.
After completion of the customized color balance adjustment (Man-
ual) with SIM 46-21 according to the user's request, use SIM 63-7
to register the service color balance target data by using adjust-
ment pattern that was printed in this mode.

In this case, be sure to use A4 or 11" x 8.5" paper for printing the
adjustment pattern by SIM 46-21.

Use SIM 63-11 to select one of the three 
kinds of color balance targets.

MX-4070N  ADJUSTMENTS AND SETTINGS  5 – 36

By this procedure, the service color balance target is revised.
It is recommended to keep the printed adjustment pattern created
with SIM 46-21. This adjustment pattern can be used to register the
same color balance target to another machine.
It is also useful to register the service color balance target data. 
Do not fold it and keep it under the circumstances which protect it
from discoloration and dirt.
The service color balance target data is registered immediately
after the color balance adjustment (Manual) with SIM 46-21.
If a considerable time has passed after completion of the color bal-
ance adjustment (Manual) with SIM 46-21, the color balance of the
adjustment pattern at the time of adjustment differs from the color
balance of the adjustment pattern printed after a considerable time.
Never use such a pattern for the adjustment.
The accuracy of the service color balance target data can be
judged as follows.
When result of the color balance adjustment (Auto) with selecting
the service color balance target in SIM 46-74/46-24 is unsatisfac-
tory or abnormal.
In that case, the registered service target data for the color balance
adjustment (Auto) may be improper.
This may be caused when an improper or abnormal color balance
adjustment pattern was used to register the service color balance
target data for the color balance adjustment with SIM 63-7.
The color balance adjustment pattern used in registration was
made and printed by the color balance adjustment (Manual) with
SIM 46-21. This procedure may have been executed erroneously

(Setting procedure of an optional color balance (gamma) as
the service color balance target)
1) Use SIM 46-21 (Copy color balance adjustment (manual

adjustment) mode) to print color patch image (adjustment pat-
tern).
In this case, be sure to use A4 or 11" x 8.5" paper for printing
the adjustment pattern by SIM 46-21.
If the color balance is shifted from the standard, an adjustment
is required. If not, an adjustment is not required. When an
optional color balance is requested by the user, make an
adjustment.

2)

Enter the SIM 63-7 mode.

3)

Place 5 sheets of white paper on the color patch image
(adjustment pattern).
If the color balance could not be adjusted satisfactorily with
SIM 46-21 (Color balance adjustment (Manual)), do not exe-
cute SIM 63-7 to register the service color balance target data.

5)

Press [EXECUTE] key.
The color patch image (adjustment pattern) is read.

The color balance (gamma) target set level of each color
(KCMY) can be checked with K/C/M/Y keys.
Check that the set level is increased in the sequence of B - P
(MAX). 
If there is no variation or variation is reversed, it is judged as
abnormal.

7)

Press [OK] key.
The color balance (gamma) of the color patch image (adjust-
ment pattern) used in the procedure 5) is set as the service tar-
get.

printer color balance adjustment (Automatic adjustment) (SIM 46-74/76-24)

A

Factory color balance 
(gamma) target

There are three kinds of the color balance targets, and each of them is specified according to the machine design. Use 
SIM 67-26 to select one of them as the factory target. The default setting (factory setting) is the color balance (DEF1) 
which emphasizes color reproduction.

B

Service color balance 
(gamma) target

This target is used when the user requests to customize the color balance to user's desired level. In advance, the user's 
unique color balance must be registered as the service color balance target. The above registration (setting) is made by 
the serviceman with SIM 67-25 to adjust the color balance and with SIM 67-27 to register it.
This color balance target is used when the user executes the color balance adjustment. When, therefore, the service color 
balance target is changed, the color balance target of the user's color balance adjustment is also changed. When, 
however, SIM 67-28 is executed, the color balance is set to the factory color balance target set with SIM 67-26. The 
default setting (factory setting) of the color balance is same as the factory color balance target. (Emphasized on color 
reproduction (DEF1))
If the user does not request for customizing the color balance, be sure to use SIM 67-28 to set the color balance to the 
factory color balance target.

a. General
SIM46-74 is used to perform the automatic copy color balance and
density adjustment (SIM46-24) and the automatic printer color bal-
ance and density adjustment (SIM67-24) continuously.
Since it is desirable to perform the copy color balance adjustment
(automatic adjustment) before the automatic printer color balance
and density adjustment, it is advisable to perform the adjustment in
this mode.
This mode is also advisable to effectively perform both of the auto-
matic copy color balance and density adjustment (SIM46-24) and
the automatic printer color balance and density adjustment (SIM67-
24). It saves considerable time when compared with performing
each of the auto copy/printer color balance and the density adjust-
ment individually.
The color balance adjustment (automatic adjustment) is used to
adjust the copy density of each of Cyan, Magenta, Yellow, and
Black automatically.
When this adjustment is executed, the color balance adjustments
of all the copy/printer modes are revised.
