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 AC 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...

Do not plug or unplug the printer when it is on. Unplugging a live connector can deform the 
plug and cause fire.
When unplugging the printer, grasp the plug instead of the power cord. Forcibly pulling the 
AC power cord can damage it and cause a fire or an electric shock.
Be sure to turn off and unplug the printer before accessing the interior of the printer for 
cleaning, maintenance, or troubleshooting. Accessing the interior of a live printer can result 
in electric shock.
