Select either
On
or
Off

automatically removed from scanned images, but scanning takes
longer.
Note:
❏
A moiré is a cross-hatch pattern that appears on scanned images
when scanning printed material. It is a result of interference that
occurs due to the difference between the pitches of the scanning and
the halftone screens.

is set to
Black & White

On
or
Off

Note:
❏
The pixel depth of output image is 24-bit color.
