USING THE TWAIN INTERFACE TO SCAN 125

Note: Also make sure to set the page size larger than the item that you’re scanning so the Autocrop to Original process will have sufficient room on the page to crop the image properly.

■AutoCrop to Length—Select this option to let the scanner automatically crop the scanned document from the top to the bottom edge of the page, affecting only the length of the document. The width of the scan area is not affected. The scan width is determined by the chosen page size.

■Filter—The 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. The Filter option applies to Black&White or Greyscale Mode.

■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 Greyscale or Color Mode at 200 dpi or less.
