To prevent fire or electric shocks, connect the green earth wire bundled with the 
power cord to one of the following: 

• 

The earth terminal of the power outlet 

• 

A piece of copper buried in the earth 650 mm or deeper 

Make sure that the earth wire on the power cord is connected before you use 
the printer. If it is not possible to make an earth connection, consult your dealer 
or Brother authorized service representative. 
Never connect the earth wire to any of the following: 

• 

Gas pipes that could ignite and explode 

• 

Telephone line earth wires or lightning rods, which can draw an excessive 
electric current if hit by lightning 

• 

Water faucets or pipes whose electrical conductivity is broken by a 
non-metallic part 

 

 

 

If the power cord is broken or insulated wires are exposed, ask your dealer or 
authorized Brother service representative. Using a damaged cord can cause fire 
or electric shocks. 

 
 

CAUTION

 

 

 

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 power cord can damage it and cause a fire or electric shocks. 

 

 

 

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 shocks. 

 

 

 

Once a month, turn off the printer and check the power cord for the following. If 
you notice any unusual conditions, contact your dealer for assistance. 

• 

The power cord is plugged firmly into the power outlet. 

• 

The plug is not excessively heated, rusted, or bent. 

• 

The plug and outlet are dust free. 

• 

The cord is not cracked or frayed.
