DocuMate 515 Scanner User’s Guide 31
Scanning
• Straighten Image—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 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.
• Invert Image—Only available for Black&White Mode, this option
reverses the black and whites of an image.
• 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 not the red
watermark. Color filter applies to Black&White or GrayScale Mode.
