To lift the printer, face the front of the printer and grip the recessed areas at the bottom left 
and right with both hands. Never try to lift the printer by gripping any other areas. Lifting the 
printer by gripping other areas can cause the printer to fall, resulting in injuries.
When lifting the printer, get a firm footing and bend your knees to avoid possible injuries to 
your back.
Do not move the printer by lifting it by the front and back edges (positions shown in the 
following illustration) when the paper tray is extended (loaded with Legal 14 paper). The 
printer may fall and result in injuries or the paper tray may be damaged.
The printer has ventilation grilles on the side and at the back of the machine. Ensure that 
the printer is installed no less than 300 mm (11.7 in.) from the wall on the right, 200 mm (7.8 
in.) from the wall on the left, and 255 mm (9.9 in.) from the wall at the back. A poorly 
ventilated printer can cause excessive internal heat to build up and result in fire. 
The illustration below shows the minimum clearances required for normal operation, 
consumables replacement, and maintenance ensuring that your printer operates at peak 
performance.
When moving the printer, be sure to unplug the power cord from the AC power 
outlet/socket. Moving the printer with the power cord connected can damage the power 
cord, which could result in a fire or an electric shock.

When moving the printer, do not tilt it more than the angles shown in the illustration below. 
If tilted excessively, the printer may fall, resulting in injuries.
■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, remove the toner cartridge. 
■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.

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 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 the 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 
AC 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.
WARNING
 
						

							 XXIII
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.
Do not use conductive paper, e.g. carbonic paper and coated paper. When paper jam 
occurs, they can cause a short circuit and fire.
Once a month, turn off the printer and check the AC power cord for the following.
■The AC power cord is plugged firmly into the AC 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.
■If you notice any unusual conditions, call your dealer or Brother Customer Service for 
assistance.
When the printer is not used over an extended period of time, it is advisable to unplug the 
printer.
Switch off the printer before connecting the interface cable or options. Connecting the 
interface cable or options to a live printer can cause electric shocks.
CAUTION
 
						

							XXIV   
This printer may interfere with radio or television reception, causing flickering or distortion. This can be 
determined by turning the printer off and on. To correct interference, perform one or a combination of the 
following procedures:
■Move the printer away from a TV and/or radio.
■Reposition the printer, TV and/or radio.
■If the printer, TV and/or radio are plugged to the same AC power outlet/socket, unplug them, then 
plug them into different AC power outlets/sockets.
■Reposition the TV and/or radio antennas and cables until the interference stops. For external 
antennas, call your local electrician.
■Use coaxial cables with radio and television antennas.
Operating Precautions
Do not place any liquid containers such as vases or coffee cups on the printer. Liquids spilt 
on the printer can cause a fire or electric shock.
Do not place any metal parts such as staples or clips on the printer. If metal or flammable 
materials get into the printer, they can short circuit internal components and cause a fire or 
electric shocks.
If debris (metal or liquid) gets into the printer, turn off and unplug the printer. After that, call 
your dealer or Brother Customer Service immediately. Operating a debris-contaminated 
printer can cause a fire or electric shocks.
Never open or remove printer covers that are secured with screws unless specifically 
instructed to do so in the this guide. High-voltage components can cause electric shocks.
Do not try to alter the printers structure or modify any parts. Unauthorized modifications can 
cause fire.
This printer complies with the IEC60825 (Class 1) international laser standard. This means 
that the printer does not present any risk of injury to individuals from laser radiation. Various 
covers confine the laser radiation to the inside of the printer; hence, users cannot incur 
injury from the laser under normal operating conditions. Removing covers, unless 
instructed to do so in this guide, can cause injury from laser radiation.

							 XXV
Never touch an area indicated by a high-temperature warning label (on or near the fuser 
unit). Touching these areas may result in burns.
If a sheet of paper is wrapped around the fuser or rollers, do not use excessive force to 
remove it so as to avoid injuries or burns. Turn off the printer immediately and call your 
dealer or Brother Customer Service.
Do not place any heavy objects on the printer. An off-balance printer can fall over or the 
heavy object can fall, resulting in injuries.
Do not use highly flammable sprays or solvents in or around the printer, as this can result 
in fire.
When removing paper jams, make sure that no pieces of paper are left inside the printer, 
as this can cause fire.
If the paper is wrapped around the fuser or roller, or you cannot see the jam that you are 
trying to clear, do not attempt to remove the paper by yourself, as this may result in injuries 
or burns. Turn off the printer immediately and call your dealer or Brother Customer Service.
Do not place magnetic objects near the safety switch of the printer. Magnets can activate 
the printer accidentally, resulting in injuries.
Refer to this guide for procedures on clearing paper jams and how to resolve any other problems that

Notes on Handling Consumables
Never put a toner cartridge into a naked/open flame. It can explode, resulting in injuries.
Never put a transfer roll cartridge into a naked/open flame. It can explode, resulting in 
injuries.
Never heat the drum or scratch its surface. A heated or scratched drum can be hazardous 
to your health.
Do not use a vacuum cleaner for cleaning any spilled toner. Use a cloth soaked with soapy 
water to wipe it out. The vacuumed toner may cause a fire in the cleaner due to its electrical 
sparks.
■Do not open consumables until you are ready to use them. Do not store consumables in the following 
conditions:
■Hot or humid areas
■Near a naked/open flame
■Exposed to direct sunlight
■Dusty areas
■Before using consumables, read the instructions and precautions provided with the 
consumables.
■Administer emergency first aid as follows:
■
Eye Contact: Flush eyes with plenty of water for a minimum of 15 minutes, and seek medical advice.
■
Skin contact: Wash material off skin with plenty of soap and water.
■
Inhalation: remove person to fresh air, and seek medical attention.
■
Ingestion: If toner is swallowed, get immediate medical attention or advice.
■When you remove the transfer roll cartridge from the printer because the waste toner collection box 
is full, do not attempt to empty the waste toner box and reuse the cartridge, as toner may spill inside 
the printer and cause damage. Loose toner can spill inside the printer and deteriorate print quality.
