    Issue


    Cause and Solution

    Check 1: Increase the scanning resolution
    Adjusting Color Mode and Output (Scan) Resolution
    What is Resolution?
    The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.54 cm).
    The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.

    Check 2: Set the scale to 100%
    Some applications do not display images clearly if the image is too small.

    Check 3: Update the calibration data
    In ScanGear (scanner driver), perform Platen Calibration on the Scanner tab of the Preferences dialog box. Calibration may take time depending on your computer.

    Check 4: If moire (stripe pattern) appears, take the following measures and scan again
    • On the Basic Mode tab of ScanGear, select Magazine(Color) in Select Source.
    • On the Advanced Mode tab of ScanGear, set Descreen in Image Settings to ON.
    NOTE
    If moire appears when you scan a digital print photo, take the above measures and scan again.

    • If you use MP Navigator EX, set Document Type to Magazine(Color) or enable Descreen in the Scan Settings dialog box and scan again.

    Check 5: Check the monitor's color depth
    • Windows 7:
    From the Start menu, select Control Panel > Appearance and Personalization > Adjust screen resolution > Advanced settings.
    On the Monitor tab of the displayed dialog box, set Colors to High Color (16 bit) or True Color (32 bit).
    • Windows Vista:
    From the Start menu, select Control Panel > Appearance and Personalization > Adjust screen resolution to open the Display Settings dialog box. Set the color depth to Medium (16 bit) or Highest (32 bit).
    • Windows XP:
    From the Start menu, select Control Panel > Display to open the Display Properties dialog box. On the Settings tab, set Color quality to Medium (16 bit) or Highest (32 bit).
    • Macintosh (Mac OS X v.10.5.x or Mac OS X v.10.4.x (10.4.11 or later)):
    In the System Preferences screen, click the Displays icon, then in the Colors of the Display tab, select Thousands or Millions.

    Check 6: Clean the Platen and Document Cover
    Clean the Platen or the Document Cover of the scanner, taking special care not to press strongly on the Platen.

    Check 7: If the document is in poor condition (dirty, faded, etc.), use Reduce Dust and Scratches, Fading Correction, Grain Correction, etc. in Image Settings on the Advanced Mode tab of ScanGear
    Adjusting Image Settings

    Check 8: If the color tone of images is different from the original document, take the following measures and scan again
    • On the Advanced Mode tab of ScanGear, set Image Adjustment in Image Settings to None.
    • On the Color Settings tab in the Preferences dialog box of ScanGear, set Color Matching.

    Check 9: Cover the machine with black cloth if white spots, streaks, or colored patterns appear in scan results due to interference from ambient light
