scanned in black and white. Select Grayscale to scan objects containing drawings or black-and-white photo- graphs. The scanning produces an image in varying shades of gray. Select Color to scan color photographs and other color objects.

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. 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.

Brightness and Contrast — Drag the sliders to the right or left to adjust the brightness and contrast of the scanned image.

7.Click the Page Settings tab to adjust the scanning page settings.

8.Adjust the desired page settings.

Page Size — Choose one of the page sizes from the drop-down list. The outlines on the picture repre- sent the various page sizes. Clicking on one of those outlines also selects it as the page size for the scan. If you select the Custom option from the drop-down list, boxes appear in place of the picture. Enter the hori- zontal and vertical page dimensions for your scan in those boxes.

AutoCrop — Select this option to let the scanner automatically determine the size of the object being scanned. For example, if you put a

photo in the middle of the glass, the scanner will automatically determine the size of the photo. When AutoCrop is selected, the scanner makes two passes — the first pass senses the object's size, and the second pass scans the image. This option overrides the Page Size menu selection.

DeScreen — Select this option when scanning a picture from a newspaper or magazine article, or another object that contains images with patterns or dots. Scans of patterns or dots sometimes have a distorted or wavy appearance. The scanner scans the object to compensate for the patterns and dots, and produces a clearer image. The scanning may slow down a bit when this option is selected. Do not select this option when scanning photo- graphs.

Gamma — Drag the slider to improve how the colors in a scanned image look on your moni- tor. Gamma correction allows you to achieve precise color matching. Because the computer cannot always transmit the exact color information to the hardware, you may have to make some color adjustments using the Gamma fea- ture.

The default Gamma setting works fine in most cases and normally does not need to be adjusted.

9.Click Close. The USB Scanner dia- log box reappears. The new config- uration and its adjusted settings now apply to the button.
