2. Copier-specific Adjustments
(6) Enter adjustment mode [05]. Change the values for codes [7190] to [7192] and [7956] to [7959] to adjust the
gamma balance in each of medium- and high-density areas.

Set a value larger
than 128.
0 to 255 128
* Set the value in increments of approximately 20, while checking the copy image until the optimum value is
obtained.
(Please be careful because the gradation (or density) of the medium-density area may exceed that of the
high-density area, depending on the set value.)
* The subcode varies according to the area where the density is adjusted. Refer to the table below and set
the subcode for the area to be adjusted. The density of light text or a graphic image will vary, if the
medium- or high-density area is mainly adjusted. Setting "0" for the subcode allows you to adjust the low-
density area. But it will not affect the light text or graphic images. Therefore, never change the value for
the low-density area.
Subcode Area where the density is adjusted
1 Medium-density area
2 High-density area
Precautions after the completion of the adjustment
The adjustment may possibly cause an increase in the amount of toner used, moiré, blurred text (small, dark text
blurred), diminished photo images or gradational images (less accurate reproducibility of halftones). Therefore,
carefully perform the adjustment, while checking the copy image.
Remarks
Enter a value within the recommended value range mentioned in the procedures. Otherwise, it may cause a loss in
MFP performance, including degradation in the image quality and a reduction in the life of the consumables.
