When "COMPLETE THIS PROCEDURE" is displayed, the
adjustment operation is completed. Cancel SIM 46-74.

(8.5/7.0 Inch LCD model)

NOTE: The adjustment result becomes valid only when the both

adjustments in the copy mode and in the printer mode are
completed.

For example, if the copy color balance adjustment (auto-
matic adjustment) is performed and the simulation is can-
celed, the adjustment result is invalid.

10) Check the copy color balance and density.

There are two methods to check the color balance and density.

Use the servicing color test chart (UKOG-0326FCZZ/UKOG-
0326FC11) 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
14C).

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
14C).

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.

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. If the color balance of the adjustment
pattern printed in this mode is slightly shifted to Magenta, it is
converted into the natural gray color balance by the color table
in an actual copy mode. (When the color balance target is DEF
1.)

11) Use SIM 44-26 to perform the half tone image correction.

 (Compulsory execution)

• Enter the SIM 44-26 mode and press [EXECUTE] key.

• [EXECUTE] key is highlighted and the operation is started.
