    for and the name of the button appear.

Adjusting Scan and Page Settings

If you use a scan configuration that you define yourself, you can adjust 
that configuration's scan settings and page settings.  For example, if the 
scanned image is too dark, you can adjust the brightness of the scan 
setting.

Note:  You can adjust only the settings for the configurations that you
       define yourself.  You cannot change the scan settings or page
       settings for any of the pre-defined scanning configurations.

Follow these steps to adjust scan and page settings.

1.  Hold down any button on the scanner.  The USB Scanner Utility
    Preferences dialog box appears.  The selected tab on the dialog box
    corresponds to the button you pressed.  You can click the other tabs
    for the other buttons.

2.  In the Configuration to Use list, click the configuration you want to
    adjust.

    Note: You cannot edit or change pre-defined configurations.  To make a
          change, you must create a new configuration or copy an existing
          one and give it a new name.

3.  If you have not defined a configuration yet, click New to create a new
    one.  You can also select one of the pre-defined configurations then
    click Copy to copy it.

4.  Click Edit.  A dialog box appears.

5.  Enter a name for the new configuration.

6.  Adjust the desired scanning options.

    Mode - Select Black/White to scan in black and white.  For example,
    letters and memos are usually scanned in black and white.  Select
    Grayscale to scan objects containing drawings or black and white
    photographs.  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 represent 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 horizontal and vertical page
    dimensions for your scan in those boxes.

    Auto-Crop - 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 Auto Crop 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.

    De Screen - Select this option when scanning a picture from a
    newspaper or magazine article, or another object that contains images
    with patterns of 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 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.

9.  Click Close.  The USB Scanner dialog box reappears.  The new
    configuration and its adjusted settings now apply to the button.

Note: If you click COPY/PRINT or FAX, 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 menu for more information.

Pre-Defining Scan Settings

Selecting the proper scan setting before final scanning provides the best 
results.  The scan setting determines the sharpness of the object and the 
number of possible shades of gray or color.  Scan settings also affect the 
speed of the scan and the file size.

The following table shows the pre-defined scan settings you can use.

Adjusting Brightness and Contrast

The scanner's Advanced Settings lets you adjust a scanned object's 
brightness and/or contrast as desired.  For example, you can improve 
legibility of a black and white document written with a light pencil by 
adjusting brightness to be darker.  You can adjust the brightness and 
contrast while scanning the object's grayscale and/or color.  If an object 
is currently displayed in the preview area, the changes you make using the 
Brightness and Contrast control bars are reflected in the previewed object

Follow these steps to adjust brightness and contrast.

1.  Start the Paper Port software.

2.  Click the Twain icon on the command bar or click Acquire on the File
    menu.  The USB Scanner dialog box appears.

3.  Click Adv. Setting on the USB Scanner dialog box.  The Advanced
    Settings dialog box appears.

4.  Click User defined to change the settings.

5.  Drag the Brightness slider to the left to make the scanned object
    darker, or the right to make the scanned object lighter.  When you
    release the mouse button, the change is reflected in the preview
    object.

6.  Drag the Contrast slider to the left to decrease the contrast or to
    the right to increase the contrast for the scanned object.

Note:  See the Help menu for more details about the Advanced Settings
       dialog box.
