■ 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 straighten
correctly. In that case, re-scan the page using the paper guides to
feed the paper in straight.
■ Autorotate 90—Select this option to rotate the scanned image
90
o
clockwise when scanning is finished. Typically you use
Autorotate 90 so you can select any of the page sizes from the
Standard menu but scan in landscape orientation instead of
portrait. Landscape scanning tends to be faster than portrait
scanning.
■ Invert Image—Only available for Black&White Mode, this
option reverses the black and whites of an image.
■ Duplex—Scan both sides of the page. If this option is not
selected, the scanner will scan the front side of the page only.
■ Skip Blank Originals—Skips pages that are completely blank.
Typically you use this option when you will scan a stack of two-
sided pages which have a number of blank sides. This option is
only available for Duplex scanning.
■ 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
Original Image. Inverted Image.
