* 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.
