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 300dpi or less.
■
Straighten Image —Select this option to let the scanner
automatically determine if a page is skewed, 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.
■
Color Filter —Color filter is the ability of your scanner to
automatically remove a color from a scanned item. For example,
if you are scanning a letter with a red watermark, you can choose
to filter out the red so the scanned letter just shows the text and
not the red watermark. Color filter applies to Black&White or
Grayscale Mode.
