■Use the printer in a place that meets the following requirements:
Ambient temperature range of 10 to 32 °C (50.0 to 89.6 °F), relative humidity of 15 to 85% (no
condensation)
When using the printer at an ambient temperature of 32 °C (89.6 °F), the relative humidity should not
exceed 65%. When the relative humidity reaches 85%, the ambient temperature should not exceed
28 °C (82.4 °F).
■Do not place the printer in a room where there are sudden fluctuations in temperature
and do not move the printer from a cold place to a warm humid place. If you do,
condensation may occur inside the printer and deteriorate print quality.
■Do not place the printer in direct sunlight, as this may damage the printer.
■When moving the printer, do not remove the toner cartridges, leave them locked in
place. Loose toner can spill inside the printer and deteriorate print quality.
■Do not place the printer directly next to an air conditioner or heater, as this affects the
temperature inside the printer and can cause damage.
■Do not use the printer when it is tilted at an angle of more than 5 degrees, as this may
result in damage.
Precautions for Power and Grounded/Earthed Connections
Use the printer within the specified power range.
AC power:100-127 V AC ± 10% (90 V-140 V) or 220-240 V AC ± 10% (198 V-264 V)
Frequency: 50 ± 3Hz/60 ± 3Hz
Ensure that the power cord connector and AC power outlet/socket are free of dust. In a
damp environment, a contaminated connector can, over time, draw non-negligible amounts
of current that can generate heat and eventually cause fire.
Do not attempt to modify, pull, bend, chafe, or otherwise damage the power cord. Do not
place objects on the power cord. A damaged power cord can cause fire or electric shock.
Never touch a power cord with wet hands. This constitutes an electric shock hazard.
