There are two kinds of the gamma target for the color balance
automatic adjustment: the factory target and the service target.
FACTORY key and SERVICE key are used to select one of the
above two.
Factory target color balance: Standard color balance
(The color balance can be selected from the three kinds of
fixed ones with SIM63-11.)

tomized according to the user's request. (Variable)
When shipping from the factory, the service target gamma data
and the factory target gamma data are the same.
Both are set to the standard color balance when shipping from
the factory. For the service target, a customized color balance

10) Check the copy color balance and density.
There are two methods to check the color balance and density.
(Method 1)
Use the servicing color test chart (UKOG-0317FCZZ/UKOG-
0317FC11) in the Text/Printed Photo mode (Manual) to check
the copy color balance and density. (Refer to the item of the
copy color balance and density check.)
When satisfactory color balance and density are not obtained
from the automatic adjustment by selecting the factory target in
procedure 4), change the factory color balance target with SIM
63-11 and repeat the procedures from 1).
If a satisfactory result is not obtained with the above proce-
dure, perform the manual color balance adjustment (ADJ
20C).
Also when the service target is selected in procedure 4) to exe-
cute the automatic adjustment and a satisfactory result is not
obtained, perform the manual color balance adjustment (ADJ
20C).
(Method 2)
By printing the color balance adjustment sheet with SIM 46-21
and comparing each process (CMY) black patch color balance
with the black patch, the color balance adjustment can be
checked more precisely.
