To use this machine safely and comfortably,
carefully read the following precautions and
install the machine in an appropriate location.
Do not install in a location that may result in a
fire or electrical shock
• A location where the ventilation slots are
blocked (too close to walls, beds, sofas, rugs, or
• A damp or dusty location
• A location exposed to direct sunlight or
• A location subject to high temperatures
• A location exposed to open flames
• Near alcohol, paint thinners or other
• Do not connect unapproved cables to this
machine. Doing so may result in a fire or
• Do not place necklaces and other metal
objects or containers filled with liquid on the
machine. If foreign substances come in
contact with electrical parts inside the
machine, it may result in a fire or electrical
• If any foreign substance falls into this machine,
unplug the power plug from the AC power
outlet and contact your local authorized
Do not install in the following locations
The machine may drop or fall, resulting in injury.
• An unstable location
• A location exposed to vibrations
Do not install in the following locations
Doing so may result in damage to the machine.
• A location subject to temperature and
humidity extremes, whether low or high
• A location subject to dramatic changes in
temperature or humidity
• A location near equipment that generates
magnetic or electromagnetic waves
• A laboratory or location where chemical
• A location exposed to corrosive or toxic gases
• A location that may warp from the weight of
the machine or where the machine is liable to
sink (a carpet, etc.)
Avoid poorly ventilated locations
This machine generates a slight amount of ozone
and other emissions during normal use. These
emissions are not harmful to health. However,
they may be noticeable during extended use or
long production runs in poorly ventilated rooms.
To maintain a comfortable working environment,
it is recommended that the room where the
machine operates be appropriately ventilated.
Also avoid locations where people would be
exposed to emissions from the machine.
Do not install in a location where condensation
Water droplets (condensation) may form inside
the machine when the room where the machine
is installed is heated rapidly, and when the
machine is moved from a cool or dry location to a
hot or humid location. Using the machine under
these conditions may result in paper jams, poor
print quality, or damage to the machine. Let the
machine adjust to the ambient temperature and
humidity for at least 2 hours before use.
Avoid installing the machine near computers or
other precision electronic equipment.
Electrical interference and vibrations generated
by the machine while printing can adversely
affect the operation of such equipment.
Avoid installing the machine near televisions,
radios, or similar electronic equipment.
The machine might interfere with sound and
picture signal reception. Insert the power plug
into a dedicated power outlet, and maintain as
much space as possible between the machine
and other electronic equipment.
In altitudes of above sea level 3,000 m or higher
Machines with a hard disk may not operate
properly when used at high altitudes of about
3,000 meters above sea level, or higher.
Connecting the Telephone Line
This machine conforms to a analog telephone
line standard. The machine can be connected to
the public switched telephone network (PSTN)
only. If you connect the machine to a digital
telephone line or a dedicated telephone line, it
might impede proper operation of the machine
and could be the cause of damage. Make sure to
confirm a type of telephone line before
connecting the machine. Contact your optical
fiber line or IP telephone line service providers if
you want to connect the machine to those
When using wireless LAN
• Install the machine at a distance of 50 meters
or less from the wireless LAN router.
• As far as possible, install in a location where
communication is not blocked by intervening
objects. The signal may be degraded when
passing through walls or floors.
• Keep the machine as far as possible from
digital cordless phones, microwave ovens, or
other equipment that emits radio waves.
• Do not use near medical equipment. Radio
waves emitted from this machine may
interfere with medical equipment, which may
result in malfunctions and accidents.
If the operating noise concerns you
Depending on the use environment and
operating mode, if the operating noise is of
concern, it is recommended that the machine be
installed in a place other than the office.
Moving the Machine
If you intend to move the machine, even to a
location on the same floor of your building,
contact your local authorized Canon dealer
beforehand. Do not attempt to move the
• Use only a power supply that meets the
specified voltage requirements. Failure to do
so may result in a fire or electrical shock.
• The machine must be connected to a
socket-outlet with grounding connection by
the provided power cord.
• Do not use power cords other than the one
provided, as this may result in a fire or
• The provided power cord is intended for use
with this machine. Do not connect the power
cord to other devices.
• Do not modify, pull, forcibly bend, or perform
any other act that may damage the power
cord. Do not place heavy objects on the
power cord. Damaging the power cord may
result in a fire or electrical shock.
• Do not plug in or unplug the power plug with
wet hands, as this may result in an electrical
• Do not use extension cords or multi-plug
power strips with the machine. Doing so may
result in a fire or electrical shock.
• Do not wrap the power cord or tie it in a knot,
as this may result in a fire or electrical shock.
• Insert the power plug completely into the AC
power outlet. Failure to do so may result in a
fire or electrical shock.
• Remove the power plug completely from the
AC power outlet during a thunder storm.
Failure to do so may result in a fire, electrical
shock, or damage to the machine.
• Make sure that the power supply for the
machine is safe, and has a steady voltage.
• Keep the power cord away from a heat source;
failure to do this may cause the power cord
coating to melt, resulting in a fire or electrical
Avoid the following situations:
If excessive stress is applied to the connection
part of the power cord, it may damage the power
cord or the wires inside the machine may
disconnect. This could result in a fire.
– Connecting and disconnecting the power
– Tripping over the power cord.
– The power cord is bent near the connection
part, and continuous stress is being applied to
the power outlet or the connection part.
– Applying excessive force on the power plug.
• Install this machine near the power outlet and
leave sufficient space around the power plug
so that it can be unplugged easily in an
