Line of Dots Appears in All Scanned Images
If a line of dots appears in all your scanned images, try these solutions:
• Clean the scanner glass with a soft, dry, lint-free cloth or use a small amount of glass cleaner on the
cloth, if necessary. Paper towels are not recommended.
Caution:
Do not spray glass cleaner directly on the scanner glass.
• Make sure any interface cables are securely connected at both ends.
• Keep the document cover closed to prevent dirt or dust from getting inside.
If you are scanning from the ADF, make sure the ADF edge guides fit against the loaded originals. You
can also try cleaning the ADF and scanning again.
