Cleaning the Platen Glass and Document Cover Important • Be sure to turn off the power and unplug the power cord before cleaning the machine. • Do not use tissue paper, paper towels, rough-textured cloth, or similar materials for cleaning so as not to scratch the surface. Paper tissue powder or fine threads may remain inside the machine and cause problems such as print head blockage and poor printing results. • Never use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to clean the machine, as this may cause a malfunction or damage the surface of the machine. With a soft, clean, lint-free and dry cloth, wipe the platen glass (A) and the inner side of the document cover (white sheet) (B) gently. Make sure not to leave any residue, especially on the glass surface. Important • The inner side of the document cover (white sheet) (B) is easily damaged, so wipe it gently. 216
