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.
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 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.
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.
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.
