7. Cleaning the Printer

Cautions When Cleaning

• To avoid hazardous electric shock or laser radiation exposure, do not remove any covers or screws
other than those specified in this manual. When the machine needs to be checked, adjusted, or
repaired, contact your service representative.
• Do not take apart or attempt any modifications to this machine. There is a risk of fire, electric shock,
explosion or loss of sight. If the machine has laser systems, there is a risk of serious eye damage.
• When removing misfed paper, do not touch the fusing unit because it could be very hot.
Clean the printer periodically to maintain fine printing.
Dry wipe the exterior with a soft cloth. If dry wiping is not enough, wipe with a soft, wet cloth that is wrung
out well. If you still cannot remove the stain or dirt, apply a neutral detergent, and then wipe over with a
well-wrung wet cloth, dry wipe, and then let it dry.
• To avoid deformation, discoloration, or cracking, do not use volatile chemicals, such as benzine and
thinner, or spray insecticide on the printer.
• If there is dust or grime inside the printer, wipe with a clean, dry cloth.
• You must disconnect the plug from the wall outlet at least once a year. Clean away any dust and
grime from the plug and outlet before reconnecting. Accumulated dust and grime pose a fire hazard.
