2. Copier-specific Adjustments
* 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 background density will vary, if the low- or medium-density
area is mainly adjusted. Setting "2" for the subcode allows you to adjust the high-density area. But it will
not affect the background density. Therefore, never change the value for the high-density area.
Subcode Area where the density is adjusted
0 Low-density area
1 Medium-density area
