Procedures
* The service technician must perform all adjustments.
(1) Enter adjustment mode [05]. Change the values for codes [7485 to 7488] to adjust the gamma curve balance
of the low-, medium- and high-density areas.

Set a value smaller than 128
to decrease the density.
Set a value larger than 128
to increase the density.
0 to 255 128
* Set the value in increments of approximately 20, while checking the scanned-in image until the optimum
value is obtained.
* 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.
Subcode Area where the density is adjusted
0 Low-density area
1 Medium-density area
2 High-density area
* Gradation in the Black mode will vary, if the medium-density area is mainly adjusted. But remember that
adjusting the low- or high-density area will rarely affect the gradation in the Black mode.
Precautions after the completion of the adjustment
Nothing in particular.
