AR-C260/C260M  SETTING AND ADJUSTMENTS  8 - 6

1) Enter the SIM44-2 mode.

2) Press the [EXECUTE] key. 

The adjustment is performed automatically. When the adjustment
is completed, the adjustment result is displayed and the the [EXE-
CUTE] key display returns to the original state.

If the adjustment is not completed normally, "ERROR" is displayed.

In that case, check the following sections for no abnormality. If there is
any abnormality, repair the part and perform the adjustment again.

In case of an error, the adjustment result is not revised.

• Image density sensor

• PCU PWB

• Transfer belt

When the color image density sensor is adjusted with SIM44-13 and
the black image density sensor is adjusted with SIM44-2, the adjust-
ment with SIM44-36 is not required. 

In addition, the color image density adjustment jig is not used.

1) Enter the SIM44-36 mode.

2) Press the [EXECUTE] key.

The adjustment is performed automatically. When the adjustment
is completed, the adjustment result is displayed and the the [EXE-
CUTE] key display returns to the original state.

If the adjustment is not completed normally, "ERROR" is displayed.
In case of an error, the adjustment result is not revised.

In that case, check the following sections for no abnormality. If there is
any abnormality, repair the part and adjust again.

• Image density sensor

• PCU PWB

• Transfer belt

This adjustment must be performed in the following cases:

• When the scanner (writing) unit is replaced.

• When the scanner (writing) unit is removed from the machine.

• When the print image is shifted. 

(Especially conspicuous for text and line drawings)
(The scanner (reading) unit is normal, but the print image focus of
the print engine is not normal.)

• When there is uneven density in the main scanning direction.

• When the color balance adjustment does not result in proper color

matching.

• When in installation or when the installing site is changed. (Neces-

sary depending on the case)
