The quality of a scanned image with Epson Scan is poor. What should I do?

• See the solutions below for your problem type.

  Spots or Lines Appear in All Scanned Images

  If spots or lines appear in all your scanned images, follow these steps to clean the scanner glass:

  1. Press the  power button to turn off the scanner.
  2. Unplug the AC adapter.
  3. Disconnect any connected cables.
  4. Pull down on the cover open lever and open the scanner cover.
     
  5. Wipe off any stains on the glass scanning surfaces using a soft, dry cloth.
     

     Note: If the glass surfaces are stained with grease or some other hard-to-remove material, use a small amount of glass cleaner on a soft cloth to remove it. Wipe off all remaining liquid.

     Caution:
     Do not spray glass cleaner directly on the scanning surfaces. Be careful not to place too much force on the glass.

  6. Plug in the AC adapter.
  7. Close the scanner cover.

  Scanned Image Edges are Cropped

  If the edges of a scanned image are cropped, try the following solutions:

  • Select Auto Detect as the Size setting (Epson Scan) or the Document Size setting (Document Capture Pro or Document Capture).
  • In Epson Scan, click Configuration and select the Document tab. Adjust the cropping area shown in Crop Margins for Size "Auto".
  • In Document Capture Pro, select Detailed Settings from the Scan window. Click Configuration and select the Document tab. Adjust the cropping area shown in Crop Margins for Size "Auto".
