type of image you are scanning. You have four choices:

l Color - The Color button is only for scanning color images.

By clicking on this button before you prescan or scan, you
allow your scanner to reproduce the colors found in the
original, and the scanner can reproduce over a trillion colors!

l Gray - The Gray Scale button uses a 256-bit grayscale to

produce images like black & white photos.

l Line Art - The Line Art button is for producing images

containing only pure black and pure white. Use this button
when scanning text. If you use this button for scanning a
photograph, the scanned image will usually have a woodcut
effect.

l Halftone -Clicking on the Halftone button mixes different

patterns of black and white to give the appearance of
shading, like in newspaper photographs.
