Ripple patterns appear in my scanned image when using Epson Scan. What should I do?

• A ripple or cross-hatch pattern (called moiré) may appear in a scanned image of a printed document. It is caused by interference from the differing pitches in the scanners screen and the halftone screen in your original.
  
  
  Select the Descreening check box in Office Mode, Home Mode, or Professional Mode. In Professional Mode, select an appropriate Screen Ruling for the Descreening and deselect the Unsharp Mask setting in Epson Scan. See Epson Scan help for details.
  
  Select a lower resolution setting.
  
  Note: You cannot remove ripple patterns when you are scanning film or monochrome images, or scanning using a resolution higher than 600 dpi.
