Cleaning and Maintenance
Service Maintenance Procedure
Perform the following procedures whenever you check, service, or repair a
printer. Cleaning the printer, as outlined in the following steps, assures proper
operation of the printer and reduces the probability of having to service the
printer in the future.
The frequency of use, Average Monthly Print Volume (AMPV), type of media
printed on, and operating environment are factors in determining how critical
cleaning the machine is and how often it is necessary. Record the number of
sheets printed.
Recommended Tools
■ Toner vacuum cleaner
■ Clean water
■ Clean, dry, lint-free cloth
■ Black light-protective bag
Cleaning
Perform the following general cleaning steps as indicated by the printer’s
operating environment.
Never apply alcohol or other chemicals to any parts of the printer. Do not use
aerosol cleaners; they may be explosive and flammable under certain
conditions.
Never use a damp cloth to clean up toner. If you remove the Print Cartridge,
place it in a light-protective bag or otherwise protect it as exposure to light can
quickly degrade performance and result in early failure.
