CHANGING THE BUTTON SETTINGS 27
DeScreen—Select this option when scanning a picture from a
newspaper or magazine article, or other item that contains images
with patterns or dots. Scans of patterns or dots sometimes have a
distorted or wavy appearance. The scanner scans the item to
compensate for the patterns and dots, and produces a clearer image.
The scanning may slow down a bit when this option is selected. You
don’t need to select this option when scanning photographs.
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.
8. Click OK.
The Preferences dialog box reappears. Make sure the configuration
you just defined is selected.
9. Click OK on the Preferences dialog box.
The new configuration and its adjusted settings now apply to the
button.
Note: If you select the Copy/Print or Fax button, the dialog box for
editing and adjusting the settings will have a Device tab for selecting
options for a printer or copier. See the Help for more information.
