7.3 Maintenance of Ink Supply and Vacuum Line System
7.3.1 Changing Defective Ink Pump and Filter
Usually the ink pump stops pumping the ink when the secondary tank is full of ink.
The level sensor will energize the LED on the Print head Control Board when the secondary
ink tank is full.
If the level LED doesn’t light after 2 minutes of pumping, then most likely the pump is
defective or there’s a leak somewhere along the input line. Please take note of the polarity
of the power supply cable for the ink pump, usually the red wire is connected to positive “+”
while the black is to negative “-”.
Change the ink and solvent filters every six months to ensure continuous ink and
solvent flow into the system.
