3.7.5 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 color

modes. The adjustment is available for both the manually-set original and the original used with the

RADF.

<Procedure>:

Procedure is same as that of "3.7.2 Density adjustment (Black Mode)".

3.7.6 Sharpness adjustment

If you want to make scan images look softer or sharper, perform the following adjustment. The adjust-

ment can be made for each of the color modes and original modes independently.

Note: Note:

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

Procedure is same as that of "3.7.2 Density adjustment (Black Mode)".
