Check the scanner glass for dirt and smudges

Over time, specks of debris might collect on the scanner glass and white plastic backing, which can affect performance. Use the following procedure to clean the scanner.

1.Press the power button to turn the printer off, and then disconnect the power cable from the electrical outlet.

2.Open the scanner lid.

3.Clean the scanner glass and the white plastic backing underneath the scanner lid with a soft cloth or sponge that has been moistened with nonabrasive glass cleaner.

CAUTION: Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon tetrachloride on any part of the printer; these can damage the printer. Do not place liquids directly on the glass or platen. They might seep and damage the printer.

4.Dry the glass and white plastic parts with a chamois or a cellulose sponge to prevent spotting.

5.Connect the power cable to an outlet, and then press the power button to turn the printer on.
