Judgment threshold for ACS (common for copy and network scan)
The judgment level is adjusted for the automatic identification of whether the original set on the
glass is black or color. Namely, this is to adjust the judgment level used when “Auto Color” is
selected at color modes. The same adjustment value is simultaneously applied to all cases of
originals on the original glass for copier functions and network scanning functions, and those
placed on the RADF.
