USING THE TWAIN INTERFACE TO SCAN 93

■Resolution—Drag the slider to the right or left to adjust the dots per inch (dpi) of the resolution. The maximum resolution is 600 dpi; the minimum is 50 dpi. This option determines the amount of detail you can see in the scanned image. The higher the dpi setting, the sharper and clearer the scanned image. However, higher dpi settings take longer to scan and produce larger files for the scanned images. Usually the higher resolution settings are used for precision work, such as photographs or fine artwork.

■Brightness and Contrast—Sometimes an image is scanned with the brightness and contrast set too light or too dark. For example, a note written with a light pencil may need to be scanned darker to improve legibility. Increasing or decreasing the brightness makes the scanned image lighter or darker. Contrast refers to the difference between the lighter and darker portions of the image. Increasing the contrast emphasizes the difference between the lighter and darker portions, decreasing the contrast de-emphasizes that difference. Contrast is used in conjunction with brightness.

■Deskew—Select this option to let the scanner automatically determine if a page is skewed when inserted into the page feed, and then straighten its image. The scanner detects page edges and can sense when the page is fed through at an angle. However, if the page is fed through at too great an angle, the page will back out of the scanner automatically. In that case, feed the paper in straight and re-scan the image.

■AutoCrop to Original—Select this option to let the scanner automatically determine the size of the item being scanned. For example, if you scan a 5" x 7" photo, the scanner will determine the size of the photo, and the scan area is the size of that photo.

When using the AutoCrop to Original option, always use the alignment arrows on the scanner to align the page so it is not skewed.
