3.5.6 Judgment threshold for ACS

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 adjustment is available for each of the manually-set original and the original used

with the RADF.

Contents

The larger the value is, the more an original tends to be judged as

black even at the Auto Color Mode. The smaller value is, the more it

tends to be judged as color.

Acceptable values: 0 to 255. (Default: 70)
