Location and Environment Precautions
Switch off the machine before connecting the interface cable or optional accessory. Connecting the
cable or accessory with a live machine can cause a shock hazard.
Location and Environment Precautions
Do not place the machine in a hot, humid, dusty, or poorly ventilated environment. Pro-
longed exposure to these adverse conditions can cause a fire or shock hazard.
When moving the machine, be sure to unplug the power cord from the outlet. If the machine
is moved with the power cord connected, it can cause damage to the cord which could result
in a fire or shock hazard.
When moving the machine, do not tilt it more than 10 degrees. If tilted excessively, the
machine may fall over and cause injuries.
The machine is capable of operating normally within the following recommended environ-
mental limits.
Temperature range 10-35°C Humidity range15-85%(no condensation)
Humidity should be 70% or below at 32°C and temperature should be 28°C or below at 85%
humidity.
Do not expose the machine to direct sunlight. Exposure to direct sunlight can adversely
affect the machine's performance.
For information on how to secure the printer against movement or tipping in case of an
earthquake, please contact your point of purchase.
Place the machine on a level and sturdy surface that can withstand the machine weight. If
tilted, the machine may fall over and cause injuries.
The machine weighs about 48kg. When carrying the equipment, play it safe. Get help.
When lifting the machine, face the front panel and firmly grip the recessed areas provided on
both sides of the machine. Never try to lift the machine by gripping any other areas. Lifting
the machine by gripping any other areas can cause the fall of the machine, resulting in inju-
ries.
When lifting the machine, get a firm footing and bend your knees to avoid possible injuries to
your back.
NOTE: Sudden temperature fluctuations can affect copy quality. Rapid heating of a cold room can
cause condensation inside the machine, directly interfering with image transfer.
CAUTION: Ensure that the plug connection is free of dust. In a damp environment, a con-
taminated connector can draw a non-negligible amount of current that can generate heat
and eventually cause a fire over an extended period of time.
CAUTION: Do not unplug or plug the machine in while it is on. Unplugging a live connector
can deform the plug and cause a fire.
