* 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.)
* Since the subcode varies according to the area where the density is adjusted, refer to the table below and
set the appropriate subcode. Remember that mainly adjusting the low- or medium-density area will change
the copy density of the images seen through the back of the page. Setting "2" for the subcode will allow
you to adjust the high-density area. But this will not solve the problem. Therefore, never change the value
for the high-density area.

Caution after the adjustment
The adjustment may possibly cause text handwritten with a pencil or light text to become illegible on the copy.
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.
