• 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.
• 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.

DEF1
The engine color balance adjustment target in the automatic color balance
operation is slightly shifted to Magenta. When this target is selected, the
color balance is converted into natural gray color balance by the color table
in an actual printer mode and print is made. (Factory setting)
DEF2
The engine color balance adjustment target in the automatic color balance
operation is slightly shifted to natural gray color balance. When this target is
selected, the color balance is slightly shifted to Cyan by the color table in an
actual copy mode and print is made.
DEF3
The engine color balance adjustment target in the automatic color balance
operation is slightly shifted to Cyan. When this target is selected, the color
balance is converted into the color balance with enhanced Cyan by the color
table in an actual copy mode and print is made.

(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. 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.
Factory setting
Use SIM 67-25 to adjust the optional color
balance, and use SIM 67-27 to register it.
Execute SIM 67-28.
(The service color balance target is
the same as the factory color balance
target.)
