CLEANING THE MACHINE DOCUMENT GLASS AND RSPF If the document glass, RSPF, or scanning glass for originals fed from the RSPF (the long narrow glass surface on the right side of the document glass) become dirty, the dirt may appear on copies. Always keep these parts clean. Stains or dirt on the document glass/RSPF will also be copied. Wipe the document glass, the RSPF and the scanning window on the document glass with a soft, clean cloth. If necessary, dampen the cloth with water. Do not use thinner, benzene, or similar volatile cleaning agents. Do not spray flammable cleaner gas. Gas from the spray may come in contact with the internal Warning electrical components or high-temperature parts of the fusing unit, creating a risk of fire or electrical shock.
