3.4.4 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.
