1-1. Precautions
Please observe the following precautions before using your printer.
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.
z 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.

Keeping your printer
32 °F to 104 °F
(0 °C to 40 °C)
20 % to 85 %
(no condensation)
Operating your printer
50 °F to 95 °F
(10 °C to 35 °C)
For the best print result

z Do not pull out Ink Cartridge(s) during the operation; it may result in poor print quality or cause damage to your
printer.
z 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 Be careful in handling a printed T-shirt that has not yet fixed by heat. Ink is difficult to wash from stained clothes.
z 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 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.
z Install the Ink Cartridges in the correct positions as shown. Confirm both the colors of labels on your printer and the
Ink Cartridges.
z 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.
