Solvent and Ink are flammable.
Eye contact with the ink and Solvent will break the cornea and weaken the eyesight.
Contact lens should not be worn when operating printer or when there is no proper
ventilation.
Wear safety glasses and gloves while flushing print heads, ink tube or moving the ink
bottles or containers.
Solvent and ink can be irritating to eyes, throat and skin. Inhaling the ink fumes would
result in swoon or other symptoms.
Solvent vapors are heavier than air and may flow and gather in low spot.
1.2.2 Danger of Fire and Explosion
Open flames, heat energy or spark around the printer can trigger fire and explosion.
No smoking, pilot lights, open flames, stoves, heaters or halogen lights should be
turned on within 5m distance from any edge of the printer.
No portable spark-producing equipment (static, ele ctrical or Mechanical) within 5m
distance from any edge of the printer.
1.2.3 Anti-ultraviolet Radiation
Wear solvent protection glasses and gloves when operating the machine and avoid
being too closer to solvent lights.
When doing maintenance task or being close to the flatbed machine, solvent lights
must be shut off or close all solvent protection doors.

Power indicator:
Power is ok, on; or, off.
Nixie Tube:
Show the error number.
0 No problem 1 Lack of ink
2 Negative problem 3 Movement problem
Error indicator----Nixie Tube
If the digital LED shows 0, it means everything is ok, with no problem.
Number 1 means that there is no ink in the secondary tank:
¾ First, check the ink bottle: make sure the ink bottle is not empty, if there is no
ink ,then load ink;
¾ Second, check the ink pump to see if it is working, replace it if necessary;
¾ Third, check the sensor: make sure the sensor can detect the level exactly,
otherwise change it;
¾ If everything can’t work still, change Servo Card.
Number 2 means some ink over flowed, which also means there is ink in the
negative pressure tank:
¾ Check the ink indicator LED is light or not, it means there is ink in the IPT
when it’s on. Then you need to suck ink out from the tank syringe b efore start
the machine
Number 3 means the movement system has problem
¾ First, check the servo driver report the error or not: if there is a error, shut
down the power of the machine and restart it.
¾ Secondly, check the limited switch: the left & right limited switches are used
for protection. If the switch is pressed, it will stop the motor from working. So
you must make sure that switch is ok and it hasn’t been pressed by carriage
or any other thing.
¾ Third, check the motor can work normally or not. If necessary, change it.
¾ Forth, if it still can work, change the USB Board.
