Use SIM46-21 to print the color balance adjustment sheet, and
check each process (CMY) black patch color balance and the black
patch in order to confirm that the color balance adjustment is
proper.

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.)

If color balance or density is not satisfied, adjust the copy and
printer color balance by SIM 46-74.

MEMO: Before checking the printer color balance and the density,
be sure to execute the following procedures in advance.

* Execute the high density image correction (Process correction)

forcibly. (SIM 44-6)

* The half-tone image correction is forcibly executed. (SIM 44-26)

Execute SIM 64-5 to print the print test pattern.

Set each set value to the default and press [EXECUTE] key. The
print test pattern is printed.

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.

1)

Enter the SIM46-74 mode.

2)

Press [EXECUTE] key.

The high density process control is performed, and the copy
color patch image (adjustment pattern) is printed out. 
(A4/11" x 8.5" or A3/11" x 17" paper is automatically selected.)

3)

Set the color patch image (adjustment pattern) paper printed in
procedure 2) on the document table.

Set the color patch image (adjustment pattern) printed in the
procedure 2) on the document table. Place the color patch
image so that the fine lines are on the left side. At that time,
place 5 sheets of white paper on the printed color patch image
(adjustment pattern).

Select [FACTORY] target, and press [EXECUTE] key.

When the color balance is customized by the manual color bal-
ance adjustment (SIM 46-21) according to the user's request,
and the color balance is registered with SIM63-7 as the service
target, if the color balance is required to be adjusted, select the
[SERVICE] target.

The copy color balance adjustment is automatically executed
and prints the color balance check patch image.

If there is any streak or unclear print on the printed check pat-
tern, check the print engine for any problems.

5)

Press [EXECUTE] key.

The printer color patch image (adjustment pattern) is printed
out. (A4/11" x 8.5" or A3/11" x 17" paper is automatically
selected.)

6)

Set the color patch image (adjustment pattern) printed in the
procedure 5) on the document table.

Set the color patch image (adjustment pattern) printed in the
procedure 2) on the document table. Place the color patch
image so that the fine lines are on the left side. At that time,
place 5 sheets of white paper on the printed color patch image
(adjustment pattern).

7)

Select [FACTORY] target, and press [EXECUTE] key.

When the color balance is customized with the manual color
balance adjustment (SIM 67-25) according to the user's
request and the color balance is registered as the service tar-
get with SIM 67-27, if the color balance is adjusted to that color
balance, select the [SERVICE] target.

The printer color balance adjustment (step 1) is automatically
performed and the color balance check patch image is printed
out.

If there is any streak or unclear print on the printed check pat-
tern, check the print engine for any problems.

8)

The initial setting menu of the half tone image correction is dis-
played. Press [OK] key.

The initial setting of the half tone image correction is per-
formed.

9)

Wait until [EXECUTE] key is displayed. When it is displayed,
press it.

The half tone image correction is performed.

10) When "COMPLETED THIS PROCEDURE" is displayed, the

adjustment operation is completed.

Cancel SIM46-74.

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
(automatic adjustment) is performed and the simula-
tion is canceled, the adjustment result is invalid.

11) 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 10C
(2)).

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
10C (2)).

12) Check the printer color balance and density.

(Refer to the item of the printer 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 7), change the factory color balance target with SIM
67-26 and repeat the procedures from 1).

If a satisfactory result on the color balance and the density is
not obtained with the automatic adjustment, execute the man-
ual adjustment (SIM 67-25) (ADJ 10E (2)).

Also when the service target is selected in procedure 7) to exe-
cute the automatic adjustment and a satisfactory result is not
obtained, perform the manual color balance adjustment (ADJ
10E (2)).

If the color balance or density is not in the satisfactory level even
after execution of the automatic and manual adjustments, there
may be another cause.

Troubleshoot the cause, repair or perform necessary works, and
repeat the adjustment from the beginning.

Make a copy in the original table mode and in the DSPF mode.
Check to confirm that the image loss and the void area are in the
range shown below.
