scanned image. You can select the entire image area or a portion of
it. You can even select multiple scan areas to create multiple
scanned images of different areas (Normal Preview mode only).
You can also use the scan area to select specific
Image Adjustments settings for a scanned image. Just be sure to
click inside the scan area before selecting the settings.
Professional Mode, the default Preview mode is Normal mode. To use
Thumbnail Preview mode instead, select the Thumbnail checkbox beneath the Preview button
(if available), then click the Preview button to preview your image
