• Auto detect color—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.

• Skip blank originals—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.

• Rotate image—Select an option in this list to have the final image rotated when scanning is complete.

Automatic recognizes text on the page and rotates the image 90, 180, or 270 degrees so the text is right

side up.

• Perform edge cleanup—Select this option to have the software remove any thin lines that may be

around the edges in the scanned image. Edge Cleanup only applies if AutoCrop and AutoDeskew are

selected so the software can determine where the edges are located. Therefore, selecting Edge Cleanup

will also select AutoCrop and AutoDeskew. This option is only available when scanning in Black&White.

• Despeckle—Speckles are small spots on an image that the scanner interpreted as a valid part of the

document. For example, an irregularity in the paper, or a small wrinkle, or the holes where a staple was

removed may show up as speckles on the scanned image. The Despeckle option identifies these spots

and removes them. This option is only available when scanning in Black&White.

• Color dropout—color dropout 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 dropout applies to

Black & White or Grayscale scanning modes.

• Bit depth reduction—Click the drop down menu and select an option from the list. The Bit depth

reduction options are only available when scanning in black and white.

Error diffusion, Bayer, and Halftone patterns are the intentional application of noise (dithering) in the

image to help alleviate banding when scanning in binary (black and white) mode. For example, if you

scan a color photo in black and white, the image file will have large blocks of black and white and the

image barely recognizable. Dithering the image creates a black and white image that is recognizable.

Dynamic threshold attempts to evaluate the scanned page and automatically adjust the brightness

and contrast levels to produce the best quality image when scanning in black and white. For example,

light color text on a page may be missing in the final image as the scanner will change those light colors

to white pixels. Dynamic threshold will attempt to automatically lower the brightness level to darken the

image, and raise the contrast level to make the difference between the lighter and darker portions of the

image clearer.
