3. Clean the scanner strip by using a damp, lint-free cloth. Clean the scanner lid backing Minor debris can accumulate on the white document lid backing that is located underneath the scanner lid. 1. Open the scanner lid. 2. Clean the white document lid backing by using a soft cloth or sponge that has been moistened with a mild soap and warm water. Also, clean the scanner strip next to the ADF scanner glass. 3. Wash the backing gently to loosen debris; do not scrub the backing. 4. Dry the backing by using a chamois or soft cloth. CAUTION Do not use paper-based wipes because they might scratch the backing. 5. If this does not clean the backing well enough, repeat the previous steps and use isopropyl alcohol to dampen the cloth or sponge, and then wipe the backing thoroughly with a damp cloth to remove any residual alcohol. 162 Chapter 10 Manage and maintain the device ENWW
