document cover, 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.

sheets
 The amount of toner consumed will vary depending on conditions of usage and the type of originals copied. 
The toner quantity display should only be used as an approximate guide.
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 
electrical shock.
