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 before 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.
