2. Copier-specific Adjustments

(3) Perform the color balance adjustment or RGB adjustment to adjust the hue.

*For further information regarding the adjustment procedures, refer to procedure (2) in 2.2 To Closely Match with the Color Balance of the Original.

After adjusting the hue, copy and check the copy image quality.

If further image quality adjustments are still necessary, use the next procedure.

(4) Enter adjustment mode [05]. Change the values for codes [1779 to 1798] to adjust the color density.

*Set the value in increments of approximately 10, while checking the copy image until the optimum value is obtained.

*Changing the values for the codes corresponding to Text/Photo mode will affect the copy image quality in Full color mode and Auto color mode.

*The subcode varies, according to the area for which the density is adjusted. Refer to the table below and

set the subcode for the area to be adjusted.

Subcode

Area for the density to be adjusted

0

Low-density area

1

Medium-density area

2

High-density area

‰Cautions after the completion of the adjustment

The adjustment may possibly cause offset failure, particularly when the highly colored original is copied in Photo mode. Also, it may cause degradation in the color reproducibility. (Excessively enhancing the tint of black makes other colors, such as skin tones, look dull.) Therefore, carefully perform the adjustment, while checking the copy image.

‰Remarks

Enter the value within the recommended value range mentioned in the procedures. Otherwise, it may cause a loss in copier performance, including degradation in the image quality and reduction in the life of the consumables.
