■ Reduce Moire Patterns—Moire patterns are wavy, rippled lines
that sometimes appear on the scanned images of photographs or
illustrations, particularly newspaper and magazine illustrations.
Selecting Reduce Moire Patterns will limit or eliminate moire
patterns in the scanned image. This option is only available for
the GrayScale or Color Mode at 200dpi or less.
■ Straighten Image—Select this option to let the scanner
automatically determine if a page is skewed, and then straighten
its image. The scanner detects page edges and can sense when the
page is fed through at an angle. However, if the page is fed
through at too great an angle, the image may not scan correctly.
In that case, re-scan the page using the paper guides to feed the
paper in straight.
■ Invert Image—Only available for Black&White Mode, this
option reverses the black and whites of an image.
Note: Also make sure to set the page size larger than the item that
you’re scanning so the Autocrop process will have sufficient room on
the page to crop the image properly.
