damage.
• To avoid hazardous electric shock or laser radiation exposure, 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

the equipment, you should take care that the power cord will not be damaged under the
equipment.
• When the machine will not be used for a long time, unplug the power cord.
• If you use the machine in a confined space, make sure there is a continuous air turnover.
• Keep the machine away from humidity and dust. A fire or an electric shock might occur.
• Do not place the machine on an unstable or tilted surface. If it topples over, it could cause in-
jury.
• After you move the machine,fix it with the caster fixture. Otherwise,the machine might move
or come down to cause a personal injury.
• Protect the equipment from dampness or wet weather, such as rain, snow, and so on.
• Do not allow paper clips, staples, or other small metallic objects to fall inside the equipment.
• Do not reuse stapled paper. Do not use aluminum foil, carbon-containing paper or other con-
ductive paper. Otherwise, a fire might occur.
• Do not eat or swallow toner.
• Keep toner (used or unused) and toner bottle out of the reach of children.
• For environmental reasons, do not dispose of the equipment or expended supply waste at
household waste collection points. Disposal can take place at an authorized dealer or at ap-
propriate collection sites.
• When removing misfed paper, do not touch the fusing section because it could be very hot.
• Do not touch the anti-humidity switch from inside the machine because it could be very hot.
• The inside of the machine could be very hot. Do not touch the parts with a label indicating the
“hot surface”. Otherwise it could cause a personal burn.
• Rolls of paper can be heavy, so you should be careful when loading one.
• This machine has been tested for safety using this supplier's parts and consumables. We rec-
ommend you only use these specified supplies.
• Our products are engineered to meet high standards of quality and functionality, and we rec-
ommend that you only use the expendable supplies available at an authorized dealer.
• This equipment is only to be installed by a qualified service personnel.

❒Do not use paper with strong curls at the edges or corners. (Curls rising more
than 5mm (1/4") or falling more than 20mm (3/4") over a 40mm (1.5") radius.)
❒When you make copies on film, take out the copies delivered to the copy exit
guide one sheet at a time and place them on a flat surface.
❒If copying to natural tracing paper (all pulp, translucent paper) at a relative
humidity of 35% or less
AIf the paper was left out of its package for 5 minutes or more, remove
the first 1000mm (39.3") before copying.
BIf copies come out wavy or with white spots, use translucent paper in-
stead of natural tracing paper.
CAlways keep the paper in a bag when not using it.
• Store the paper in a sealed polyvinyl bag if not used for a long period.
