Cause 5: Incorrect scan settings
Solution: Rescan with adjusted settings (See the CanoCraft CS-P User's Guide

Cause 6: A power cord is too close to the scanner.
Solution: Move all power cords away from the top of the scanner and
surrounding area
Glossy color photo will not scan clearly
Cause: Optical interference created by the photo adhering to
document glass produces striped patterns
Solution 1: Gently press down on the document cover
Solution 2: Move the photo on the document glass to break the adhesion
Solution 3: Clean the document glass
Stripes appear on scan of publication
Cause: Moiré effect from scan of publication at low resolution (print
screen lines highlighted by optical interference, producing
striped patterns). The appearance of this effect is dependent
upon particular combinations of screen line densities and
scanning resolutions
Solution: Rescan at different resolutions or turn on the Descreen mode
