Cautions to Take When Cleaning

R WARNING:
• Do not attempt any maintenance or troubleshooting other than that
mentioned in this manual. This machine contains a laser beam gener-
ator and direct exposure to laser beams can cause permanent eye
damage.
R CAUTION:
• The inside of this machine becomes very hot. Do not touch parts labelled
"v" (indicating a hot surface).
• Be sure to disconnect the plug from the wall outlet and clean the prongs and
the area around the prongs at least once a year. Allowing dust to build up
on the plug constitutes a fire hazard.
Clean the machine periodically to maintain high print quality.
Dry wipe the exterior with a soft cloth. If dry wiping is not enough, wipe with a
soft, damp cloth that is wrung out well. If you still cannot remove the stain or
grime, use a neutral detergent, wipe over the area with a well-wrung damp
cloth, and then dry wipe the area and allow it to dry.
Important
❒ To avoid deformation, discoloration, or cracking, do not use volatile chemi-
cals, such as benzine and thinner, or spray insecticide on the machine.
❒ If there is dust or grime inside the machine, 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. Ac-
cumulated dust and grime pose a fire hazard.
❒ Do not allow paper clips, staples, or other small objects to fall inside the ma-
chine.
