To clean the scanner glass

Page 170 highlights

To clean the scanner glass Dirty glass, from fingerprints, smudges, hair, and so on, slows down performance and affects the accuracy of special features such as fit-to-page and copy. NOTE If streaks or other defects appear only on copies produced using the automatic document feeder (ADF), clean the scanner strip (step 3). It is not necessary to clean the scanner glass. 1. Turn off the all-in-one, unplug the power cord from the electrical socket, and raise the lid. 2. Clean the glass by using 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 all-in-one; these can damage the all-in-one. Do not place liquids directly on the glass. They might seep under it and damage the all-in-one. 3. Clean the scanner strip by using a soft cloth or sponge that has been moistened with nonabrasive glass cleaner. 4. To prevent spotting, dry the glass by using a chamois or cellulose sponge. NOTE In certain areas of California, air pollution control regulations restrict the use of liquid Isopropyl Alcohol (IPA) as a cleaning agent. In those areas of California, please disregard the previous recommendations and use a dry, lint-free cloth. The cloth may be moistened with water if desired. 152 Chapter 8 Scan ENWW
