Installation Precautions

Power Source

The following are the power source requirements for this printer.

Power supply:

220 – 240 V at 50 – 60 Hz

Voltage fluctuation:

220 – 240 V ±10%

Frequency fluctuation:

Within ±3 Hz

Note

Use a power source with minimal voltage and frequency fluctuation.

Only use an outlet that is rated for the voltage capacity specified for this printer.

Be sure to plug the power cord all the way into the outlet. The outlet should be located near the printer and be easily accessible so you can unplug the power cord immediately should any problem occur.

Make sure the outlet you use is visible, and not hidden behind the printer or any other object.

If any other electrical equipment is plugged into the same outlet, make sure that the capacity of the outlet is not exceeded.

If you use an extension cord, make sure its capacity is greater than the power consumption of the printer. Using an extension cord with a lower capacity creates the danger of fire.

Never use a multiple socket to connect other appliances or machines to the same outlet being used to power the printer.
