WARNING
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 there is the danger that fire or
electric shocks could occur.
Printing
If a foreign object gets inside the printer, immediately
turn off the power switch and disconnect the power
cord, and arrange for a service call to resolve.
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 switch and disconnect the power cord.
Contact Brother to arrange a service call to resolve.
Do not use the printer when smoke or a bad odor
coming from the printer, otherwise it may cause fire
or electric shocks or problems with correct
operation.
Immediately turn off the power switch and
disconnect the power cord, and arrange for a
service call to resolve.
Environmental requirements
Use the printer in an area which is free from
sources of strong electrical noise such as electrical
line noise or static electric noise.
Sources of strong electrical noise may cause
problems with correct operation.
Any fluctuations in the power supply voltage should
be within ±10% of the rated voltage for the printer.
Voltage fluctuations which are greater than this
may cause problems with correct operation.
The power supply capacity should be greater than
the requirements for the printer’s power
consumption.
Insufficient power supply capacity may cause
problems with correct operation.
CAUTION
The ambient temperature should be within the
range of 18C to 30C during use.
Temperatures which are lower or higher than this
may cause problems with correct operation.
The relative humidity should be within the range of
45% to 85% during use, and no dew formation
should occur in any devices.
Excessively dry or humid environments and dew
formation may cause problems with correct
operation.
Use the printer in a place which is adequately
ventilated.
A slight odor is generated when the printed articles
are being fixed by heat.
In the event of an electrical storm, turn off the
power and disconnect the power cord from the wall
outlet.
Lightning may cause problems with correct
operation.

1-1. Precautions
Please observe the following precautions before using your printer.
GT-3 represents the common specifications of GT-381, GT-361 and GT-341 models. The individual
specifications are described with each model name.
Please advise the following to your customers who buy your printed materials:
Printed colors may transfer when a printed surface rubs on white or light-colored synthetic leather
made of PVC (polyvinyl chloride). When printing CMYK-only garments, the CMYK ink may transfer
to the White-only printed garment when they rub against each other. In those cases, clean the
stains with a soft cloth or toothbrush with a household cleaner or alcohol.
Wash away the pretreatment halo marks.
The printer is designed to be used within the temperature and humidity levels below. Less humidity may
cause ink clogging in Print Head nozzles and higher temperature may cause splashy print result. Use
the printer within the range of our recommendation for the best print result.
Keeping your printer
Temperature Humidity
(0 °C to 40 °C)
(no condensation)
Operating your printer
For the best print result
Do not pull out Ink Cartridge(s) during the operation; it may result in poor print quality or cause damage
to your printer.
Do not turn off your printer, or open the Front Cover during the operation; otherwise the printer may be
damaged or spoil the print job.
Be careful in handling a printed T-shirt that has not yet fixed by heat. Ink is difficult to wash from stained
clothes.
Clean the Caps and Wipers, replace the Wiper Cleaners, Fan Filter, Roller Felts (4), Flushing Plate
Sponge (top) and Flushing Plate Felt (bottom) according to our maintenance schedule to maintain good
print quality. Those Mainte nance Par ts are packed together in White, Cyan and Magenta (except 180
cc) ink Cartons. Replace them when you open the new ink cartridge or you see the warning indicated on
the display. Print quality may be damaged by insufficient cleaning, e.g. dirty printed materials, mis-firing.
Never use alcohol when you clean Head Caps and Wiper Blade; it will cause damage to the Print Heads.
Use Wash Liquid when you clean around the Print Heads.
Install the Ink Cartridges in the correct positions as shown. Confirm both the colors of labels on your
printer and the Ink Cartridges.
50 °F to 95 °F
(10 °C to 35 °C)
64 °F to 86 °F
(18 °C to 30 °C)
45 % to 85 %
(no condensation)
The printer indicates empty status "Empty XXXX (color)" when the ink cartridge is used up. Replace with
New consumables should be stored away from direct sunlight until they are required. Use up the Ink
a new Ink Cartridge. Make a new Ink Cartridge available when the icon on the Operation Panel starts
blinking. A small amount of ink remains to avoid damage to your printer.
Cartridges, Pretreatment and Maintenance Solution before the expired date, and CMYK inks should be
used up within six months after opening the new one.
GT-3 Series

Never refill ink, never reconstruct ink cartridges; ink may cohere inside the cartridge bag, tube or even
Print Head and may cause serious damage to your printer. We assume no responsibility for any problem
caused by using them. Only genuine new ink cartridges should be used.
The ink cartridges should always be installed; otherwise the needles may be sto p ped up with ink and
your printer may be damaged.
Tubes and Print Heads for White must be cleaned with Maintenance Solution once a week by the menu
Tube Cleaning. The Warning "Clean Tube W*" is indicated on the display of the Control Panel after a
week passes since the last Tube Cleaning.
If the printer is unused for a period of time there is a possibility that Print Heads and Maintenance Unit
may become clogged as ink dries. To avoid this, we recommend that the printer should be turned on at
least once a week and press the Head Cleaning Button to clean the Print Head. If you are planning not
to use your printer for more than two weeks, follow “6-2-6. Required Maintenance for the Long Storage"
to keep printer in good condition.
Shake the White Ink Cartridges once a day before you start printing (30 seconds to 1 minute for each,
1-2 minutes for new one). Hold the cartridge upside down to agitate the pigment in the bottom and
shake it horizontally.
If CMYK inks are printed on a Pretreatment applied T-shirt, ink may wash off. Do not apply Pretreatment
when you print without using White ink.
The clearance between the Clearance Sensor and the surface of the Print Heads should be app. 2 mm.
If the clearance is wider, the ink mist will spread inside the printer and the printing material, and may
damage the sensors inside. If you print with wider clearance (more than 2 mm) then check the inside of
the printer and keep it clean by referring to "6-1-6. Cleaning the inside of the printer and restart" and
"6-1-7. Cleaning the Encoder Strip".
Pretreatment mist may spread out when you use a spray and/or pretreatment applicator. Ventilate your
room in operation. Wear a face mask or goggles as necessary.
Pre-treatment on some T-shirts may be seen after applied and cured, wash lightly with water to remove
mark. Some dyes may be decolorized by Pretreatment; we recommend you test the garment before
printing.
Dispose the used waste ink, pretreatment, maintenance solution (all water-based) or other wastes in
accordance with your local regulations. Or make contact to your dealer.
The pretreated area may turn yellow when you apply Pretreatment on a white or light-colored garment.
Keep the pretreated garment away from the sunlight and wash the printed T-shirt soon.
