Auto color balance adjustment is performed with a certain color balance (gamma) as a target. There are following two kinds of targets:

Only the service target among them allows optional setup of a color balance (gamma) target.

This setup must be performed in the following cases.

• When the user requests to customize the color balance.

• When the service target gamma is found to be incorrect.

• When the copy color balance and the density adjustment is manually performed. (SIM 46-21)

• When a U2 trouble occurs.

• When the ICU main PWB is replaced.

• When the EEPROM on the ICU main PWB is replaced.

AR-C330  SETTING AND ADJUSTMENTS  7 - 35

NOTE: The above figure is for a brief description, and does not

show the actual state.

NOTE: Do not execute SIM 63-8 unless there is any special rea-

son.

This work must be executed only when the color balance is cus-
tomized by SIM 46-21.

If the color balance is not customized, there is no need to perform
this work.

Execute SIM 46-21 to adjust the color balance (Manual) according
to the user request (customized color balance). Then use the
adjustment pattern printed in this mode to register the service tar-
get gamma data with SIM 63-7.

This will revise the service target gamma data.

It is recommendable to record the adjustment pattern printed in
the above procedure. By using the adjustment pattern, the same
color balance target can be registered in another machine. It is
also useful to register the service target gamma data again.

Be careful, however, not to fold the pattern or avoid discoloration
and dirt.

Basically the service target gamma data must be registered imme-
diately after completion of the color balance adjustment (Manual)
with SIM 46-21.

If a considerable time has passed after completion of the color bal-
ance adjustment (Manual) with SIM 46-21, the color balance of the
adjustment pattern after a considerable time differs from that
before a considerable time. Do not use such an adjustment pat-
tern.

Whether the service target gamma data are correct or not can be
determined by the following.

When the adjustment result of SIM 46-24 color balance adjust-
ment (Auto) by selecting the service target is abnormal or unsatis-
factory:

In this case, the service target gamma data may be incorrect.

The possible cause is incorrectness or abnormality of the color
balance adjustment pattern used when registering the service tar-
get gamma data of the color balance adjustment (Auto) with SIM
63-7.

The color balance adjustment pattern is printed after the color bal-
ance adjustment (Manual) with SIM 46-21. The possible cause lies
in this procedure.

1) Two sheets of color patch image (adjustment pattern) are out-

putted in the copy color balance adjustment (manual adjust-
ment) (SIM 46-21). (ADJ M17/ADJ 3)

At that time, when the color balance is shifted from the stan-
dard, an adjustment is required. If not, there is no need to
adjust.

If an optional color balance is required according to the user's
request, an adjustment is required.

2) Enter the SIM 63-7 mode.

3) Press the SETUP key.

4) Set the color patch image (adjustment pattern) paper properly

adjusted and printed in the copy color balance adjustment
(manual adjustment) (SIM 46-21) (ADJ M17/ADJ 3) on the
original table.

The color patch image (adjustment pattern) printed by SIM 64-
2 may be used. In this case, check that the printed image is
proper. (The other color patch images (adjustment patterns)
printed by another machine may be used.)

Kinds

Descriptions

A

Default color 
balance (gamma) 
target (fixed)

This is the average, standard color 
balance (gamma) target determined by 
the machine design.
This color balance (gamma) target is 
identical in all the machines, without 
consideration for individuality of 
machines.
When SIM 63-8 is executed, the service 
color balance (gamma) target becomes 
the same as this target.
In SIM 46-24 (46-22) menu, this target 
is not displayed. 

B

Factory color 
balance (gamma) 
target (fixed)

This is the standard color balance 
(gamma) target which was registered 
(set) in the factory, and cannot be 
changed in the market.
This color balance (gamma) target is set 
depending on individuality of each 
machine to obtain the standard color 
balance. It, therefore, differs slightly in 
different machines. When the service 
target falls into an abnormal state by 
some reasons, this target can be used 
instead of it.
When shipping, this target is the same 
as the service color balance (gamma) 
target. 

C

Service color 
balance (gamma) 
target (variable)

This is obtained by registering (setting) 
with SIM 63-7 the adjustment pattern of 
the color balance (gamma) which was 
adjusted with SIM 46-21.
This color balance (gamma) target is set 
depending on individuality of each 
machine to obtain the standard color 
balance. It, therefore, differs slightly in 
different machines. However, an 
optional color balance (gamma) target 
can be set according to a user's 
request.
When shipping, this target is the same 
as the factory color balance (gamma) 
target.
When SIM 63-8 is executed, the service 
color balance (gamma) target becomes 
the same as the default color balance 
(gamma) target. 

Output

A: Default color balance (gamma) 
target (fixed)

B: Factory color balance (gamma) 
target (fixed)

C: Service color balance (gamma) 
target (variable)

Input

AR-C330  SETTING AND ADJUSTMENTS  7 - 36

Set the paper on the original table so that the darker density
side comes on the left side. Then place 5 sheets of white
paper on the color patch image (adjustment pattern).

If it is difficult to adjust the color balance adjustment (Manual) with
SIM 46-21 satisfactorily, do not register the service target gamma
data with SIM 63-7.

5) Press the EXECUTE key.

The color patch image (adjustment pattern) is read.

6) Press the REPEAT key and set the second color patch image

(adjustment pattern) on the original table.

The color balance (gamma) target setup level of each color can be
checked with K/C/M/Y keys.

The setup level values must be in the ascending sequence of B -
0. If there is no change or the sequence is reversed, it is judged as
an abnormality.

In case of an abnormality, resolve the problem and check again.

7) Press the OK key.

The color balance (gamma) corresponding to the color patch
image (adjustment pattern) printed in the copy color balance
adjustment (manual adjustment) (ADJ M17/ADJ 3) is set as
the service target.

Do not execute this procedure unless there is any special reason.

∗

Only when the factory target is judged as abnormal in the auto-
matic color balance adjustment by SIM 46-24, this procedure is
required in the following case:

When the ICU EEPROM data are destroyed by U2 trouble.

When SIM 63-8 is executed, the service target gamma data are
changed to the default target gamma data determined by the
machine design.

When the color balance adjustment (Auto) is executed with the
service target gamma data set to the default target gamma, a vir-
tually satisfactory result will be obtained.

1) Enter the SIM 63-8 mode.

2) Press the EXECUTE key.

3) Press the YES key.

The service target becomes the same as the default (stan-
dard) target.

NOTE for SIM 46-1 and 46-2:

The major purpose of these simulations is to delete background
copy simply.

SIM 46-1 and 46-2 are used to adjust the copy density in the low-
density area, and they do not affect the density in the high-density
area.

Note that the tone and the color phase may be changed greatly if
the set value is changed greatly.

When an extreme background copy is produced, use ADJ M17/
ADJ 3 Color balance adjustment (Manual) (SIM 46-21) instead of
this procedure.

The adjustment result of SIM 46-1 is reflected evenly to all the
color copy modes.

The adjustment result of SIM 46-2 is reflected evenly to all the
monochrome copy modes.

1) Enter the SIM 46-1 or 46-2 mode.

2) Select the copy mode to be adjusted with the scroll key.

3) Enter the adjustment value with the 10-key, and press the

[OK] key.

To increase the density in the low-density area, set a greater
adjustment value. To reduce the density, set a lower adjustment
value. The adjustment in the low-density area can be adjusted
individually for each copy mode.

The greater the set value is, the greater the density in the low-den-
sity area is, and vice versa. (The density in the high-density area is
not changed.)

4) Cancel the simulation mode, and make a copy in the normal

mode to check the copy density in the white area and the low-
density area by using the test chart (UKOG-0283FCZZ).

In this simulation mode, press CLOSE key to jump to the normal
copy mode and make actual copies of the service chart and user
documents. In this manner, the adjustment result can be checked.

The adjustment can be performed also by switching between the
simulation mode and the normal copy mode alternately and check-
ing the adjustment result with actual copies.

Serviceman chart (Color patch section)

Check the copy density in the low-density area
and the white area of the color patch section.

AR-C330  SETTING AND ADJUSTMENTS  7 - 37

This adjustment must be performed in the following cases:

• When a U2 trouble occurs.

• When the ICU main PWB is replaced.

• When the EEPROM of the ICU main PWB is replaced.

Used to adjust the gamma and the density in each copy mode individually. The adjustment in each copy mode is not required normally, but
is performed when the user requests it.

1) Enter either of SIM 46-10, 46-19 modes. (Select the simulation according to the copy mode to be adjusted.)

∗

The copy color balance and the density in the color enhancement mode are automatically determined by the adjustment result of the
color normal mode. The adjustment unique to this mode cannot be made.

2) Select the color to be adjusted with the color select key, and select the adjustment point with the scroll key.

3) Enter the adjustment value with the 10-key, and press the OK key.

The adjustment value can be selected in the range of 1 – 999. When the automatic color balance and the density are adjusted with SIM
46-24, all the set values of this simulation are set to 500.

To increase the density, increase the adjustment value. To decrease the density, decrease the adjustment value.
