• Color Filter —Color filter is the ability of your scanner to automatically remove a color from a
scanned image. For example, if you are scanning a letter with a red watermark, you can choose to
filter out the red so the scanned letter just shows the text and not the red watermark. Color filter
applies to Black & White or Grayscale scanning modes.
• Double Feed Detection —Selecting this option turns on the scanner hardware feature that
detects when multiple pages feed through the scanner at one time. This option is only available if
the scanner supports this feature.
Abort —scanning stops and all pages scanned in this batch, up to this point, will be deleted.
Prompt —you will be prompted to remove the pages in the ADF, restack the remaining pages and
continue scanning. All pages scanned before and after the double page feed are saved.
Advanced Settings tab
Use the Advanced Settings tab to set color correction options for Color or Grayscale scanning. Drag
the sliders to the left and right to change the color settings. As you do, the image changes to show the
effects of the new settings.
• Color saturation —the strength or purity of a color. This option is only available when the selected
scan mode is Color.
• Color hue —the color your eyes see as reflected from the image. This option is only available when
the selected scan mode is Color.
• Gamma —is the tone curve and the starting point for image enhancement. As you raise or lower
the Gamma value, the values at which saturation, hue, brightness and contrast affect the image
are changed. It is recommended that you keep the default Gamma value or adjust this setting
before adjusting the other options. This option is available for both Color and Grayscale scanning.
