  • Note that the item names and assignable values will vary depending on the machine.
  • The Contrast option is available only when selecting the Gray (Error Diffusion), True Gray, or 24bit Color options from the Scan Type settings.
  1. Scan Type
    Select the Photo, Web, or Text option depending on the type of document you want to scan.
    Scan (Image Type) Resolution Scan Type
    Photo Use for scanning photo images. 300 x 300 dpi 24bit Color
    Web Use for attaching the scanned image to web pages. 100 x 100 dpi 24bit Color
    Text Use for scanning text documents. 200 x 200 dpi Black & White
  2. Resolution
    Select a scanning resolution from the Resolution drop-down list. Higher resolutions take more memory and transfer time, but produce a finer scanned image.
  3. Scan Type
    Select from a range of scan colour depths.
    • Black & White
      Use for text or line art images.
    • Gray (Error Diffusion)
      Use for photographic images or graphics. (Error Diffusion is a method for creating simulated grey images without using true grey dots. Black dots are put in a specific pattern to give a grey appearance.)
    • True Gray
      Use for photographic images or graphics. This mode is more accurate because it uses up to 256 shades of grey.
    • 24bit Color
      Use to create an image with the most accurate colour reproduction. This mode uses up to 16.8 million colours to scan the image, but it requires the most memory and has the longest transfer time.
  4. Document Size
    Select the exact size of your document from a selection of preset scan sizes.

    If you select Custom, the Custom Document Size dialog box appears and you can specify the document size.

  5. Brightness
    Set the Brightness level by dragging the slider to the right or left to lighten or darken the image. If the scanned image is too light, set a lower brightness level and scan the document again. If the image is too dark, set a higher brightness level and scan the document again. You can also type a value in the field to set the brightness level.
  6. Contrast
    Increase or decrease the Contrast level by moving the slider to the right or left. An increase emphasises dark and light areas of the image, while a decrease reveals more details in grey areas. You can also type a value in the field to set the contrast level.
  7. 2-sided Scanning
    Scan both sides of the document. When using the Automatic 2-sided Scan feature, you must select the Long-edge binding or Short-edge binding option from the 2-sided Scanning drop-down list, so when you turn the pages, they are facing the way you want.
  8. Advanced Settings
    Configure advanced settings by clicking the Advanced Settings button in the Scan Settings dialog box.
