By (2) Size Recognition, whether the original is recognized as full color or black-and-white
depends on the continuity of the chromatic color in (1) Chromatic Color Recognition.
The original is recognized to be full color only if chromatic color pixels are detected continually.
If interspersed minute chromatic color pixels are detected (as shown below), the original is not
recognized as a full color original.
In “A.C.S. Sensitivity”, you can adjust the level of (2)Size Recognition for
recognizing whether the original is full color or black-and-white.
From both Copier or Scanner application, you can specify this setting in the 5-level scale, from
0 (Black & White) to 4 (Full Color).
• Adjust the A.C.S. Sensitivity in Classic (Legacy UI) copier or scanner. There is no
5-level scale in New (Simple UI) Copier or Scanner application.
