Ripple Patterns Appear in an Image You may see a ripple pattern (called a moiré) in scanned images of printed documents. This is caused by interference from differing pitches in the scanner's screen and your original's halftone screen. To reduce this effect, adjust these Epson Scan settings (if available) and try scanning again: • Select the Descreening setting. • Select a lower Resolution setting. Parent topic: Solving Scanned Image Quality Problems Image is Scanned Upside-Down Your product scans using the Auto Photo Orientation setting. This setting checks the preview image for faces, the sky, and other features, and then correctly rotates the photo when it is scanned, if necessary. If your photo is not oriented correctly using this option, deselect the Auto Photo Orientation setting and scan again.
