Scanning from TWAIN DocuMate 742
3-4 User’s Guide
• Deskew—Select this option to let the scanner automatically determine if a page is skewed,
then straighten its image. If the page is fed through at too great of 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.
• Duplex—Scan both sides of the page. If this option is not selected, the scanner will scan
the face-down side of the page only.
• Color Filter—Color filter is the ability of your scanner to automatically remove a color from
a scanned image. 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 scanning modes.
• Double-Feed Detection—Selecting this option turns on the scanner hardware feature that
detects when multiple pages feed through the scanner at one time.
Abort—scanning stops and all pages scanned in this batch, up to this point, will be deleted.
Prompt—you will be prompted to remove the pages in the ADF, restack the remaining
pages and continue scanning. All pages scanned before and after the double page feed are
saved.
• AutoCrop to original—Select this option to let the scanner automatically determine the
size of the item being scanned.
Always use the paper guides on the scanner so the page is not skewed. Skewed pages may
not crop properly.
• Reduce Moiré Patterns—Moiré patterns are wavy, rippled lines that sometimes appear on
the scanned images of photographs or illustrations, particularly newspaper and magazine
illustrations. Selecting Reduce Moiré Patterns will limit or eliminate moiré patterns in the
scanned image. This option is only available at lower resolutions.
• Define page size—Click this option to activate the Define button. Then click the Define
button to see the Define page size dialog box for selecting a specific page size.
Standard—Click the menu arrow and choose a page size from the list.
Custom—Enter the horizontal and vertical page dimensions in the boxes. Click the
name of the units, inches or mm (millimeters), to toggle between them.
Click OK.
The currently selected page size appears in the middle of the TWAIN interface on the left-
hand side.
• AutoScan on document insertion—AutoLaunch™ technology senses when an item is
inserted into the paper feed and starts scanning immediately. If this option is not selected,
the scanner waits for you to click the Scan button.
