1. Read This First
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 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.
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.
