Always keep these parts clean.

cover/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
electrical components or high-temperature parts of the fusing unit, creating a risk of fire or
