MX-2300/2700 N/G ADJUSTMENTS 6 – 56
• Relationship between the factory target and the service target and the color balance target for the user color balance adjustment in the
printer color balance adjustment (SIM 67-24)
• Factory target in the printer color balance adjustment (SIM 67-24)
By use of SIM 67-26, 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)
Each of the three color balances cannot be changed. (Fixed)
• Service color balance target in the copy color balance adjust-
ment (SIM 67-28).
For the service color balance target, an optional color balance
can be adjusted with SIM 67-25 and registered with SIM 67-27.
When, however, SIM 67-28 is executed, the color balance is set
to the same balance as the factory color balance target set with
SIM 67-26.
For the service color balance target, an optional color balance
can be adjusted with SIM 67-25 and registered with SIM 67-27.
When, however, SIM 67-28 is executed, the color balance is set
to the same balance as the factory color balance target set with
SIM 67-26.
• 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 (SIM 67-24). When, therefore,
the service color balance target is changed, this target is also
changed accordingly.

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 67-25.
the purpose of registration)
This procedure must be executed only when the color balance is
customized with SIM 67-25.
If the color balance is not customized, this procedure is not
required.
After completion of the customized color balance adjustment (Man-
ual) with SIM 67-25 according to the user's request, use SIM 67-27
to register the service color balance target data by use of the
printed adjustment pattern.
By this procedure, the service color balance target is revised.
It is recommendable to keep the printed adjustment pattern with
SIM 67-25. 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 are basically registered
immediately after the color balance adjustment (Manual) with SIM
67-25.

MX-2300/2700 N/G ADJUSTMENTS 6 – 57
If a considerable time has passed after completion of the color bal-
ance adjustment (Manual) with SIM 67-25, 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 correctness of the service color balance target data can be
judges as follows.
Select the service color balance target with SIM 67-24 and execute
the color valance adjustment (Auto), and check the adjustment
result. When the result is unsatisfactory or abnormal, 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 67-27.
The color balance adjustment pattern used in registration was
made and printed by the color balance adjustment (Manual) with
SIM 67-25. This procedure may have been executed erroneously.
