* Set the value in increments of approximately 20, while checking the copy image until the optimum value is
obtained. Note that gradations (density level) in the medium- and high-density areas may be reversed with
some setting values.
* Subcodes to be entered differ depending on the target density area. Refer to the table above to enter the
subcode for the area to be adjusted. The density of thin text or illustrations is changed by adjusting mainly
the setting value for the medium- or high-density area. Do not change the setting value for the low-density
area because if the subcode is set at "0", the density of the low-density area is adjusted but there is little or
no effect on changing the density of thin text or illustrations.
After changing the value, make a copy and check the image quality.
If further image quality adjustments are necessary, reset all the values changed in steps (1) to (4) above to
the default one and then follow the next step.
