3.2.6 Judgment threshold for ACS (common for copy & 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 a color
mode. The same adjustment value will be applied to all cases of the copying, network scanning, RADF
scanning and manual scanning (using the original glass) simultaneously.
<Adjustment Mode (05)>
Make a test copy and compare the image obtained with the current settings; if necessary and make
adjustment.
<Procedure>
The procedure is the same as that of P.3-34 "3.2.2 Density adjustment".

adjustment.
You have to make adjustment by balancing between moire and sharpness.
