A line or line of dots always appears in my scanned images. What should I do?

• Try the following:
  • The glass surface inside the scanner may need cleaning. See Cleaning Inside the Scanner. If you still have the problem, the glass surface inside the scanner may be scratched. Contact Epson.
  • If you scan a plastic card with a shiny surface, a line may appear.
  • You may need to perform a calibration. See Calibrating the Scanner for details.
