1-1. Precautions  
Please observe the following precautions before using your printer.  
z
z
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:  
z
Printed colors may transfer when a printed surface rubs on a 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.  
z
Wash away the pretreatment halo marks.  
z
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.  
Temperature  
32 °F to 104 °F  
(0 °C to 40 °C)  
Humidity  
20 % to 85 %  
(no condensation)  
Keeping your printer  
Operating your printer  
50 °F to 95 °F  
(10 °C to 35 °C)  
35 % to 85 %  
(no condensation)  
64 °F to 86 °F  
For the best print result  
(18 °C to 30 °C)  
z
z
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.  
z
z
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  
Maintenance Parts 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.  
z
z
z
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.  
The printer indicates empty status "Empty XXXX (color)" when the ink cartridge is used up. Replace with 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.  
z
New consumables should be stored away from direct sunlight until they are required. Use up the Ink Cartridges,  
Pretreatment and Maintenance Solution before the expired date, and CMYK inks should be used up within six  
months after opening the new one.

z
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.  
z
z
The ink cartridges should always be installed; otherwise the needles may stopped 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.  
z
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 “6-2-5. Required Maintenance for the Long Storage" in the Instruction Manual to keep printer in  
good condition.  
z
z
z
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 "5-1-6. Cleaning the inside of the printer and restart" and "5-1-7. Cleaning the Encoder Strip".  
z
z
z
z
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.

Before using your printer, it needs to be correctly setup as described in this chapter.  
WARNING  
Do not handle the power cord with wet hands, otherwise it may cause electric shocks.  
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.  
CAUTION  
Setting up and moving of the printer should only be carried out by a qualified technician.  
The printer machine weighs approximately 111 kg (245 lb). Transporting and setting up of the printer  
should be held in proper way. The machine may fall down and cause injury.

As for GT-381 and GT-361, do not leave the White ink inside the printer. White pigment precipitates and may cause  
serious damage to your printer. Before you start your job, shake the cartridges for 30 seconds to 1 minutes and execute  
[Daily Cleaning White] to flush the white-less White Ink. Clean the tubes once a week with Maintenance Solution.  
Follow the steps of "5-2-1. Daily Cleaning White for replacing dull White Ink" and “5-2-2. White Tube Cleaning ".  
z
Do not turn off your printer when it is operating. It may cause serious damage to your printer. If you turn off your printer  
accidentally during the operation, immediately restart it, and then turn it off correctly following the steps described in this  
section. If the power supply stops in printing by accident and will not recover soon, then turn OFF the printer and apply  
the Print Head Protection Films packed in the Print Head to cover the nozzles of the Print Heads so that the Films  
should protect the nozzles from drying. Wash the surface of the Print Head Protection Films with either the  
Maintenance Solution or Wash Liquid to protect the Print Head Nozzles from dust. After the power supply is available,  
remove the Print Head Protection Films and turn ON the printer for initialization and do Head Cleaning.

If the printer is unused for a long time we recommend turning on your printer once a week and press the Head Cleaning  
Button to protect the Print Heads and Maintenance Unit from drying and clogging. This ensures the ink is kept free  
flowing. As for White Print Heads, do the powerful cleaning with maintenance solution.  
If you are planning not to use your printer for more than two weeks, follow “6-2-5. Required Maintenance for the Long  
Storage" in the Instruction Manual to prevent ink clogging.
