The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed. The density level of each color must be almost at the
same level.
b. When the PCL mode is not supported: (In the case of GDI
model)
Use SIM 67-25 to print the color balance adjustment sheet and
compare each process (CMY) black patch color balance and the
black patch to check the color balance.

Patch B may not be copied.
Patch A must not be copied.
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. In an actual print mode, it is converted into the natural gray
color balance by the color table. (When the color balance target is

a. General
The color balance adjustment (auto adjustment) is used to adjust
the print density of each color (Cyan, Magenta, Yellow, Black) auto-
matically with SIM 67-24 or the user program.
(When this adjustment is executed, the color balance adjustments
of all the print modes are revised.)

mode is used.) (The color balance target is the service target.)
The auto color balance adjustment by the user is provided to
reduce the number of service calls.
If the print color balance is lost for some reasons, the user can
use this color balance adjustment to recover the balance.
When, however, the machine has a fatal problem or when the
machine environment is greatly changed, this function does
not work effectively.
On the other hand, the auto color balance adjustment by the
serviceman functions to recover the normal color balance

the normal color balance.
To perform the adjustment, the above difference must be fully
understood.

There are two kinds of the gamma target for the color balance
auto adjustment; Factory and Service.
[FACTORY] key and [SERVICE] key are used to select one of
the above two.
Factory target color balance: Standard color balance (It can be
selected from the three kinds of fixed color balances with SIM
67-27.)
Service target color balance: The color balance can be cus-
tomized according to the user's request. (Variable) When ship-
ping, the service target gamma data and the factory target
gamma data are the same.
Both are set to the standard color balance when shipping.
For the service target, the customized color balance gamma
can be registered with SIM 67-28.
