select the Custom option from the drop-down list, boxes appear in place of the picture. Enter the horizontal and vertical page dimensions in the boxes.
AutoCrop—This option lets the scanner automatically determine the size of the item being scanned. For example, if you scan an unusual page size, the scanner will automatically determine the size of the page.
DeScreen—Select this option when scanning a picture from a newspaper or magazine article, or other items that contain images with patterns or dots. These patterns and dots sometimes cause a wavy appearance for which the Descreen option can compensate.
The following example shows the effect of descreening a scanned image from a magazine article.
Original Image | Descreened Image |
The scanning may slow down a bit when descreen is selected. The
DeScreen setting does not apply to the Black/White mode.
Gamma—Drag the slider to improve how the colors in a scanned image look on your monitor. 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 feature.
The default Gamma setting works fine in most cases and normally does not need to be adjusted.
