WARNING
Basic precautions
To prevent accidents and problems, do not modify
the machine yourself. Brother will not be held
responsible for any accidents or problems
resulting from modifications made to the machine.
Do not handle the power cord with wet hands.
Otherwise, it may cause electric shocks.
Installation
Do not set up the printer in a dusty environment. If
dust collects inside the printer, it may cause fire or
electric shocks or problems with correct operation.
Be sure to connect the ground. If the ground
connection is not secure, you run a high risk of
receiving a serious electric shock, and problems
with correct operation may also occur.
Do not bend the cords excessively or fasten them
too hard with staples or anything similar to secure
cords. Otherwise it may cause fire or electric
shocks.
Printing
If a foreign object gets inside the printer,
immediately turn off the power, disconnect the
power cord, and contact the place of purchase or a
qualified technician. If you continue to use the
printer while there is a foreign object inside, it may
result in fire or electric shocks or problems with
correct operation.
Do not allow the printer to come into contact with
liquids. Otherwise it may cause fire or electric
shocks or problems with correct operation.
If any liquid gets inside the printer, immediately
turn off the power, disconnect the power cord, and
contact the place of purchase or a qualified
technician.
Do not use the printer when smoke or a bad odor
is coming from the printer. Otherwise it may cause
fire or electric shocks or problems with correct
operation. Immediately turn off the power,
disconnect the power cord, and contact the place
of purchase or a qualified technician.

SAFETY INSTRUCTIONS
WARNING
Printing
Keep your finger or any body part away from the
rotating fan. Otherwise it will be caught up, which
results in injuries.
Turn off the power when you approach the fan.
CAUTION
Environmental requirements
Use the printer in a place which is adequately
ventilated. A slight odor is generated when the
printed articles are being fixed by heat.
Installation
Setting up and moving of the printer should only be
carried out by a qualified technician.
The printer machine weighs 120 kg (265 lb).
Transporting and setting up of the printer should
be held in the proper way. Otherwise it may fall
down and cause injury.
When the printer falls down, disconnect the power
cord and contact the place of purchase or a
qualified technician. If you continue to use it, it may
result in fire or electric shocks or poor printing
quality.
Do not place the printer on a shaky table or high
shelf or other unstable location. Otherwise it may
tip over or fall down and cause injury. Furthermore,
the table that supports the printer should be at
least 35.4 in. (90 cm) in width and 23.6 in. (60 cm)
in depth, and should be able to bear a weight of
150 kg (330 lb) or more.
Do not set up the printer in a place where it will be
affected by vibration. Otherwise the printing quality
may be degraded or the printer may fall down,
which causes injury or results in failure of the
printer.
Do not connect the power cord until installation is
complete. The printer may operate if the power is
turned on by mistake, which could result in injury.
Do not climb onto the printer or place heavy
objects on top of it. Otherwise it may become
unbalanced and tip over or fall down and cause
injury.
Be careful not to touch the claws of the mounting
portion on the upper side of the rear cover.
Otherwise you may be injured.
Printing
This printer should only be used by operators who
are appropriately trained in its safe operation.

iv
CAUTION
Printing
Ensure there is adequate space left in front of the
printer and avoid placing any objects. Otherwise
your hand may get caught between the platen and
an object, which may result in injury.
Do not handle the platen while printing. If your
hand gets caught between the platen or the T-shirt
tray and the covers, it may be injured.
Do not put your hands inside the covers while the
printer’s power is turned on. Otherwise your hands
may touch against moving parts and this may
result in injury.
When the pretreatment is applied to printed
objects (like a T-shirt) with a spray or pretreatment
applicator, sprayed mist is generated. So wear a
pair of plastic gloves, a mask and protective
glasses (or goggles) designed to shield against
liquid splash, and fully take care of the air
ventilation when you are working with it.
When a problem occurs with the operation of the
printer, contact the place of purchase or a qualified
technician.
Maintenance
Be careful not to get your fingers caught when
closing the front cover, otherwise it may result in
injury to your fingers.
When you mount or replace the head, be careful
not to get your hands or fingers caught. Otherwise
you may be injured.
Do not disassemble the ink pouch. If the ink gets
into your eyes or onto your skin, it may cause
inflammation. In case of contact with eyes, do not
rub but immediately rinse the eyes with water.
Do not drink liquids such as the ink, maintenance
solution, cleaning solution, pretreatment, or waste.
They may cause diarrhea or vomiting.
Avoid causing your eyes or skin to make contact
with the ink, maintenance solution, cleaning
solution, pretreatment or waste. It may cause
inflammation. In case of contact with eyes, do not
rub but immediately rinse the eyes with water.

Waste ink tank
Fix the waste ink tank to the table leg or the like by using two
pieces of string, etc. Insert the waste ink tube and the waste ink
tube fixing rubber.
IMPORTANT
The waste ink tube contained in the waste ink
tank should be cut down to around 1.6 to 2 in. (4
to 5 cm) remaining just inside the tank. If the tip
of the waste ink tube is immersed in the liquid, it
will prevent the smooth flow of the waste ink, to
disable the ink suction operation of the head
cleaning function.
Avoid placing the waste ink tube horizontally as
much as possible, and be sure not to let it bend.
Otherwise the waste ink may have difficulty
flowing through the tube.
TIPS
Install the waste ink tank in the front, because it
must be emptied when the waste ink is full.
