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.

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

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. 

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

This work must be executed only when the color balance is custom-
ized 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 adjust-
ment pattern printed in this mode to register the service target 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 immedi-
ately 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 pattern.

Whether the service target gamma data are correct or not can be de-
termined by the following.

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

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

The possible cause is incorrectness or abnormality of the color bal-
ance adjustment pattern used when registering the service target
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 output-

ted in the copy color balance adjustment (manual adjustment)
(SIM 46-21). (ADJ M17/ADJ 3)
At that time, when the color balance is shifted from the standard,
an adjustment is required. If not, there is no need to adjust.
If an optional color balance is required according to the user’s re-
quest, 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 ad-

justed 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 an-
other machine may be used.)
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).

A: Default color balance (gamma)

B: Factory color balance (gamma)

C: Service color balance (gamma)

7 –  38

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 (ad-

justment 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 ab-
normality.

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 im-
age (adjustment pattern) printed in the copy color balance adjust-
ment (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
automatic 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 serv-
ice target gamma data set to the default target gamma, a virtually sat-
isfactory 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 (standard)
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-den-
sity 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 proce-
dure.

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 mono-
chrome copy modes.

1) Enter the SIM 46-1 or 46-2 mode.

(AR-C150)

(AR-C250/C160/C270)

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 adjust-
ment 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-density
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 docu-
ments. 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 checking
the adjustment result with actual copies.
