Safety Precautions

■

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 
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% (90V-140V) or 220-240 V AC ± 10% (198V-264V)

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 otherwise damage the AC power cord. Do not place objects 
on the AC power cord. A damaged AC power cord can cause fire or electric shock.

Never touch an AC 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 AC power outlet/socket. After that, call your dealer or Brother Customer Service 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.

To prevent fire or electric shocks, connect the AC power cord to a grounded/earthed AC power outlet/
socket.For your safety, if in any doubt about the effective grounding/earthing of the power, call a qualified 
electrician.

If the power cord is broken or insulated wires are exposed, stop using the printer immediately, turn it off, 
and disconnect the AC power cord from the AC power outlet/socket. After that, call your dealer or Brother 
Customer Service. Using a damaged cord can cause fire or an electric shock.

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 AC power cord. Forcibly pulling the AC power 
cord can damage it and cause a fire or an electric shock.
