What should I do to fix the quality of a scanned image with EPSON Scan?
The solution will depend on the problem you're having. See the solutions below for your problem.
Image Consists of a Few Dots Only
Line of Dots Appears in All Scanned Images
Caution: Do not spray glass cleaner directly on the scanner glass.
Straight Lines in an Image Appear Crooked
Image is Distorted or Blurry
Image Colors are Patchy at the Edges
Image is Too Dark
Back of Original Image Appears in Scanned Image
Ripple Patterns Appear in Image
You may see a rippled pattern (called a moiré) in scanned images of a printed documents. This is caused by interference from the 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:
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.
Scanned Image Colors Do Not Match Original Colors
Printed colors can never exactly match the colors on your computer monitor because printers and monitors use different color systems: monitors use RGB (red, green, and blue) and printers typically use CMYK (cyan, magenta, yellow, and black).
Check the color matching and color management capabilities of your computer, display adapter, and the software you are using to see if they are affecting the palette of colors you see on your screen.
To adjust the colors in your scanned image, adjust these EPSON Scan settings (if available) and try scanning again:
Scan Area Not Adjustable in Thumbnail Preview
Scanned Image Edges are Cropped
If the edges of a scanned image are cropped, make sure your original is placed correctly for scanning. If necessary, move your original away from the edges of the scanner glass slightly.
