Precautions for Power and Ground (earthed)
Connections
WARNING
Use the printer within the specified power range.
AC power: 100-127 VAC ± 10% (90V-140V) or 220-240 VAC ± 10% (198V-264V)
Frequency: 50 ± 3Hz/60 ± 3Hz
Ensure that the power cord connector and power 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 shocks.
Never touch a power cord with wet hands. This constitutes an electric shock
hazard.
In the following situations, stop using the printer immediately, turn it off, and
disconnect the power cord from the socket. After that, contact your dealer or
authorized Brother service representative immediately. Continued use of the
printer in such situations could result in fire.
• There is smoke emanating from the printer or the outside of the printer is
excessively hot.
• Unusual noises are coming from the printer.
• There is water inside the printer.
