• Advanced Clarity—Produces a clear, legible image even for documents that have complex or
textured backgrounds, such as graph paper, blueprints, and security paper. The Advanced Clarity
option identifies the text and drawings in the foreground and produces a scan image that keeps
the background from obscuring them. This option is only available when scanning in Black&White.
• AutoOrientation—Recognizes text on the page and rotates the image 90, 180, or 270 degrees so
the text is right side up. The AutoDeskew option must also be selected with the AutoOrientation
option.
• Auto Color Detect—Determines if a document contains color or not and produces the
appropriate scanned image. Typically, Auto Color Detect is used when you have a stack of pages
to scan, some color and others not. Instead of you having to change the scan settings from Color
to Black&White and back again, the scanner can choose the correct settings automatically.
• Blank Page Deletion—Recognizes when a page is blank and removes its image. For instance, if
you are scanning a stack of pages that includes a blank page, its image will not be included with
the other images from the stack.
• Background Smoothing—Sometimes a document with a background color on the page will
produce a scanned image that has small imperfections in the color. This option recognizes a
document’s background color and makes sure it is a smooth, solid color. Background Smoothing is
not available for Black&White scan configurations.
