When installing or moving
WARNING
For the U.S.A. and Canada
Multifunctional Digital Systems require 110 to 127 V, 10 A, 50/60 Hz electric power.
For the EU
Multifunctional Digital Systems require 220 to 240 V AC, 5 A, 50/60 Hz electric power.
Except the U.S.A., Canada and the EU
Multifunctional Digital Systems require 220 to 240 V AC, 5 A, 50/60 Hz electric power.
Do not use a power supply with a voltage other than that specied.
Avoid multiple connections in the same outlet. This could cause a re or give you an electric shock. If
you are considering increasing the number of outlets, contact an electrician.
Always connect this machine to an outlet with a ground connection to avoid the danger of re or
electric shock in case of short-circuiting. Contact your service representative for the details. Be sure
to use a 3-conductor, grounded wall outlet.
In areas, except the U.S. and Canada, where a 2-pin plug is used, the machine must be grounded for
safety. Never ground it to a gas pipe, a water pipe, or any other object not suitable for grounding.
Plug the power cord securely into the outlet. If it is not plugged in properly, it could heat up and
cause a re or give you an electric shock.
Do not damage, break or attempt to repair the power cord.
The following things should not be done to the power cord.
_ Twisting it
_ Bending it
_ Pulling it
_ Placing anything on it
_ Heating
_ Situating it near radiators or other heat sources
This could cause a re or give you an electric shock. If the power cord is damaged, contact your
dealer.
The socket outlet shall be near the equipment and be easily accessible.
Pull out the plug from the outlet more than once a year to clean around the prongs. Accumulating
dust and dirt could cause a re due to the heat released by electric leakage.

- 11 -
CAUTION
When removing the plug from the outlet, do not pull the power cord. Always hold the plug when
removing it from the outlet. If the power cord is pulled, the wires may break and this could cause a
re or give you an electric shock.
Make sure that the ventilation holes are not blocked.
If the temperature within the machine becomes too high, a re could result.
Other points
Be sure to x the power cable securely so that no one trips over it.
Adverse environmental conditions may affect the safe operation and performance of the machine,
and the machine could break down.
_ Avoid locations near windows or with exposure to direct sunlight.
_ Avoid locations with drastic temperature uctuations.
_ Avoid too much dust.
_ Avoid locations that suffer from vibration.
Make sure that the air is able to ow freely and that there is sufcient ventilation. Without adequate
ventilation, the unpleasant odor released by ozone will begin to dominate the atmosphere.
When using the machine
WARNING
Do not take off the cover of the equipment; otherwise you could be injured or get an electric shock.
Do not remove or connect the plug with wet hands, as this could give you an electric shock.
Do not place any container with liquid (ower vases, coffee cups, etc.) on or near the equipment.
This could cause a re or give you an electric shock.
Keep paper clips and staples away from the air vent. If not, a re could result or you could get an
electric shock.
If the machine becomes excessively hot, smoke comes out of it or there is an odd smell or noise,
proceed as follows.
Turn the main power switch OFF and remove the plug from the outlet, then contact your service
representative.
If the machine will not be used for more than one month, remove the plug from the outlet for safety purposes
during that time. If an insulation failure occurs, this could cause a re or give you an electric shock.
CAUTION
Do not place heavy objects (8 Kg/18 lb. or more) on the original glass and do not press on it with
force. Breaking the glass could cause personal injury.
Do not place heavy objects (8 Kg/18 lb. or more) on the machine. If the objects fall off, this could cause injury.
Do not touch the fuser unit or the metal area around it. Since they are very hot, you could be burned
or the shock could cause you to injure your hand in the machine.
Be careful not to let your ngers be caught when closing the tray. This could cause an injury.
Be careful not to let your ngers be caught between the equipment and the duplexing unit or
automatic duplexing unit. This could cause an injury.
Do not touch the metal portion of the guide plate in the duplexing unit or automatic duplexing unit as
it could burn you.
Do not touch the hinge (= a connecting part) on the rear side of the Reversing Automatic Document
Feeder. This could catch and injure your ngers when you open or close the Reversing Automatic

- 12 -
Document Feeder.
Always keep hands and ngers clear of the nisher tray hinge, as the tray could move unexpectedly.
Failure to do so could result in injury to your hand and/or ngers.
Do not use the pulled out tray as steps. This could injure you if you fall.
When changing the angle of the control panel, be careful not to catch your hands in the gap between
the equipment and the control panel. This could cause personal injury.
Do not place objects of weighing 3.3 kg/7.3 lb. or more on the optional work table. Breaking the
work table could cause personal injury.

- 13 -
Other points
Be very careful to treat the touch panel gently and never hit it. Breaking the surface could cause
malfunctions.
Be sure to turn the power OFF when leaving the ofce or if there is a power outage. However, do not
turn the power OFF if the weekly timer is in use.
Be careful because the paper exit area and paper just after exiting are hot.
Do not place anything other than paper on the receiving tray. This could disturb a normal operation
and cause malfunctions.
Do not touch the photoconductive drum and transfer belt. This could cause image problems.
Do not open/close the covers and the MPT, or pull out the trays during printing.
During maintenance or inspection
WARNING
Never attempt to repair, disassemble or modify the machine by yourself. You could cause a re or get
an electric shock.
Do not let liquids such as water and oil get into the machine when cleaning the oor. This could cause
a re and give you an electric shock.
CAUTION
Always keep the plug and outlet clean. Prevent them from accumulating dust and dirt. This could
cause a re and give you an electric shock due to the heat released by electric leakage.
Do not touch the stapling area. The actual needle point could cause you personal injury.
Other points
Do not use such solvents as thinner or alcohol when cleaning the surface of the machine.
_This could warp the shape of the surface or leave it discolored.
_When using a chemical cleaning pad to clean it, pay attention to any cautionary points.

- 14 -
When handling supplies
CAUTION
Never attempt to incinerate toner cartridges and waste toner boxes. Dispose of used toner cartridges
and waste toner boxes in accordance with local regulations.
Other points
Read the user's manual carefully to replace the toner cartridge using the correct procedure. An
improper procedure could cause toner leakage or scattering.
Do not open the toner cartridge forcibly. This could cause toner leakage or scattering.
Keep the toner cartridge out of the reach of children.
If toner is spilt on your clothes, wash it off with cold water. If you use warm water, your clothes will
be permanently stained with toner because it will not come out.
If toner leaks from the toner cartridge, be careful not to inhale or touch it.
First-aid measures
If you inhale or touch toner, etc; carry out the following treatment.
Inhalation: Remove from exposure area to fresh air immediately. Contact a physician if there is
any difculty in breathing or other signs of distress.
Skin Contact: Wash with soap and water. Wash clothing before reuse. If irritation occurs or is
persistent, seek medical attention.
Eye Contact: Immediately ush eyes with plenty of water for at least 15 minutes. If irritation
persists, call a physician.
