4.5.2 White ink circulation system
White ink is different from other color ink, because it is easy to sediment. Circulation system
is specially designed for this property of white ink. The system can make white ink circulate in the
ink line, which will also protect head nozzles from clogging.
4.5.3 Ink alarm system
Ink alarm system plays a part in caution when the ink bottle is empty or the secondary tank is
not full.
The level sensor in the bottle detects the level of ink inside, the print head board will send the
level signal to the servo card. The servo card will process this signal then control the pump working
or activate the buzzer.
4.5.4 Negative pressure system
Negative pressure system is used to hold the ink from dripping out of the print head nozzles.
Pressure settings vary on every machine. The recommended setting range is from -2.4 to -3.0Kpa.
Too low negative pressure setting will result to ink dripping or print head cannot jet ink. Too high
negative pressure setting will cause ink starving over time and ink overflow in the negative
pressure line system.
Note:
Push the arrow up and arrow down
buttons simultaneously to reset the
negative pressure to zero.
Please refer to negative pressure setting
parameters for further details
