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.

The scanner automatically locates and

appears without white borders. (If the

edges of the location.) If the document
type is photo, Auto Locate applies to each
photo; otherwise it covers the whole area
of the image.
