value is obtained.
• The value for the code corresponding to the original mode (Text/Photo, Text, or Printed Image) will
affect the copy image quality in the Full color mode and the Auto Color mode.
• 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.
