NOTE: If streaks or other defects appear only on copies made by using the document feeder, clean
the scanner strip with a soft cloth or sponge that has been moistened with nonabrasive glass cleaner.
The scanner strip is located along the left-hand side of the scanner glass. It is not necessary to clean the
entire scanner glass.
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 glass and white plastic backing.
