Scanning Basics
2-7
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.

Auto Locate:
The scanner automatically locates and
selects the target image. The image
appears without white borders. (If the
document type is document or Text/Line
Art, a 2 mm margin is added around all
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.
