An Image on the Back of Your Original Appears in Your Scanned
Image
If your original is printed on thin paper, images on the back may be visible to the scanner
and appear in your scanned image. Try scanning the original with a piece of black paper
placed on the back of it. Also make sure the Document Type and Image Type settings are
correct for your original. See "Selecting Basic Settings" on page 26 for details.
Ripple Patterns Appear in Your Scanned Image
A ripple pattern (called moiré) is a pattern that may appear in a scanned image of a printed
document. It is caused by interference from the differing pitches in the scanner’s screen
and the halftone screen in your original.
