(Abnormal end (Auto transition))
After completion of the operation, the simulation is canceled.
This procedure is to save the copy color balance adjustment
data as the reference data for the half tone correction.
Immediately after execution of ADJ 20C (Color balance adjust-
ment, Manual) with SIM 46-21, be sure to execute this proce-
dure.
When ADJ 20B (Color balance adjustment, Auto) is executed
with SIM 46-24, this procedure is automatically executed.
When [EXECUTE] key is pressed, it is highlighted and the
operation is started.
8) Use SIM 44-26 to execute the half tone image correction.
(Forcible execution)
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 com-
pletion of the operation, "COMPLETE" is displayed.

(Abnormal end (Auto transition))
After completion of the operation, the simulation is canceled.
9) Make a copy of the servicing color test chart (UKOG-
0317FCZZ/UKOG-0317FC11) and a user's document accord-
ing to necessity in the Text/Printed Photo mode (Manual) and
check the adjustment result again. (Refer to the item of the
copy color balance/density check.)
If the copy color balance and density are not adjusted to the
specified level, 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.
NOTE: If the color balance is customized, use SIM 63-7 to register

ance target)
a. General
When the automatic color balance adjustment is executed, a cer-
tain color balance (gamma) is used as the target.
There are following three kinds of the target.
• Factory color balance (gamma) target
• Service color balance (gamma) target
• User color balance (gamma) target
In the above three, only the service color balance target can be set
to a desired level.
This adjustment is required in the following cases.
* When the copy color balance/density adjustment (manual adjust-
ment) is executed with SIM 46-21).
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
* The scanner control PWB has been replaced.
* The EEPROM on the scanner control PWB has been replaced.
* When the user requests for customizing the color balance.
* When the service color balance target gamma is judged as
improper.
• Each color balance target for the copy color balance adjustment

the color balance as the service target.
If the color balance is not customized, this procedure is not
required.
If the customized color balance is registered as the service
target, the automatic color balance adjustment can be
made in the next color balance adjustment.
In the next color balance adjustment, select the service tar-
get color balance in the automatic color balance adjust-
ment mode to make an adjustment to the similar color
balance as the registered color balance.
