AutoCrop to original—select this option to let the scanner automatically determine the size of the
item being scanned. This option may occasionally be grayed out, not all TWAIN scanning applications
support this feature. Always use the paper guides on the scanner so the page is not skewed. Skewed
pages may not crop properly. This option is only available if the scanner supports this feature.
Detect stapled documents—select this option to have the scanner warn you if a stapled page has
been detected. When the scanner detects the stapled page it will stop scanning so that you can fix the
problem and start the scan again.
Skew detection—this option detects when a page has been fed through at an angle. Select an option
from the drop menu to turn on this feature. When scanning, always make sure the paper guides have
been properly adjusted to the width of the documents in the input tray. This helps to prevent the pages
from being pulled through at an angle.
• Detect and stop—the scanner stops scanning when the skewed page is detected and waits for
you to correct the problem. You can stop the scan job completely by pressing the Start/Stop
button on the scanner.
• Detect and correct—The scanner detects and attempts to automatically correct the problem.
Double Feed Detection (DFD)—this option detects when two or more pages are fed through the
scanner at the same time. When this option is turned on, ultrasonic waves are aimed at the document
to detect multiple pages by the level at which the waves pass through the pages. The accuracy of this
sensor depends on paper thickness and whether or not creasing is in the original document. Standard
printer paper between 16lb and 20lb works best with this feature.
