ROUTINE MAINTENANCE
CLEANING THE DOCUMENT GLASS/SPF/RSPF AND
DOCUMENT COVER
If the document glass, SPF/RSPF, underside of the document cover, or the scanner for originals coming from the
SPF/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/SPF/RSPF will also be copied. Wipe the document glass, document cover
portion of the SPF/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 use flammable spray to clean the machine. 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.
