Cautions to Take When Cleaning

• Do not remove any covers or screws other than those specified in this manual. Some parts of the
machine are at a high voltage and could give you an electric shock. Also, if the machine has laser
systems, direct (or indirect) reflected eye contact with the laser beam may cause serious eye damage.
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.
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, moist cloth that is wrung
out well. If you still cannot remove, use a neutral detergent, and then wipe over with a well-wrung wet
cloth, dry wipe, and let it dry.
• To avoid deformation, discoloration, or cracking of surfaces and components, do not use volatile
chemicals, such as benzine and thinner, or spray insecticide near 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 and around the plug and outlet before reconnecting. Accumulated dust and grime pose
a fire hazard.
