∗ 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.
∗1: Select either one. The default setting differs depending on the destination.
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 245 to 755. 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.
ADJ 11F CCD gamma adjustment
(CCD calibration)
(Copy document copy mode)
This adjustment is the CCD gamma adjustment (CCD calibration)
for the copy document copy mode, and is different from the CCD
gamma adjustment (CCD calibration) in the normal document
copy mode (ADJ 11A). There are above two kinds of the CCD
gamma adjustment (CCD calibration), and both adjustments are
required.
This adjustment is required in the following cases:
• After execution of the CCD gamma adjustment (CCD calibra-
tion) (normal document copy mode) (ADJ 11A) and when the
copy color balance is customized with SIM46-21.
(1) Note before adjustment
∗ Check that the table glass, No. 1/2/3 mirrors, and the lens sur-
face are free from dirt and dust.
(If dirt or dust is found, clean with alcohol.)
∗ Check that the patches of BK1 and BK2 of the SIT chart
(UKOG-0280 FCZZ are free from dirt or dust.
If dirt or dust is found, clean with alcohol.
If any damage is found, replace with a new one.
∗ Since this adjustment is based on the normal document copy
mode CCD gamma adjustment (CCD calibration) (ADJ 11A),
the said adjustment must have been completed before execu-
tion of this adjustment.
The copy color balance must also have been adjusted properly.

contact with the document table.
2) Close the document cover without shifting the SIT chart
(UKOG-0280FCZZ).
3) Make a copy in the Manual Photo mode.
(Be sure to use the specified copy paper.)
4) Set the copy made in procedure 3) on the document table so
that the center of the copy paper comes to the center of the
left edge of the document table.
