Document Settings TWAIN Scanning GuideUser’s Guide 29Skip Blank OriginalsSelect this option to have the scanner detect if a blank page has been fed through the scanner,and remove it from the final file.• Blank threshold—you can use the Threshold slider to fine tune the sensitivity of the blankimage detection. The results will depend on the scan settings and the types of documentsbeing scanned. In general leave the threshold level at the default setting if you are scanninggood-quality documents printed on standard 20lb printer paper. Try lowering the sensitivitylevel if your documents contain light colored text or drawings so those pages are not detectedas blank. Raise the sensitivity level if you are scanning double-sided light-weight paper whereimages from the opposite side of the page may appear in the image of the blank side.Clean Up EdgesSelect this option to remove any thin lines from around the edges of the final scan. This option willfill the margins of the image with the detected edge color. When you select this option, the Widthinput field will automatically enable for you to input the size of the area you want to have filledwith the background color. You can specify a fill size between approximately 0.04 to 0.39 inches(1 mm to 10 mm).Automatic Image CroppingDepending on the scanner model and installed software, there may be more than one automaticcropping option in the interface.• Crop to original—select this option to let the scanner automatically determine the size ofthe item being scanned. This option is only available if the scanner supports this feature. Thisoption may occasionally be grayed out as not all scanning applications support this feature.Always properly adjust the paper guides to the width of the paper in the input tray so that thepages feed into the scanner as straight as possible. Skewed pages may not crop properly.• Crop to length—this option tells the scanner to crop the final image to the bottom of thepage being scanned. This option is only available if the scanner supports this feature. Thisoption may occasionally be grayed out as not all scanning applications support this feature.Compression OptionsThere are two types of image compression functions used during scanning. The inputcompression option is compressing the image when transferring it from the scanner to the TWAINdriver on the computer. The output compression option is the TWAIN driver compressing theimage before it sends the image to the scanning application. In the scanning interface the inputcompression option is Compress transfers and the output option is Compression.The Compress transfers option described herein compresses the image for faster transfer fromthe scanner to the computer. The driver uncompresses the image and transfers the uncompressedimage to the scanning application. The Compression option will often be disabled as mostapplications do not support receiving a compressed image file from the scanner driver.
