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.
