sensor will energize the LED on the Print head Control Board when the secondary ink tank is full.
If the 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 three months or approximately 800 operational
hours to ensure continuous ink and solvent flow into the system.
7.3.2 Changing Defective Air Pump
If the time for the ink to reach the secondary ink tank is longer than 2 minutes, the pump
might be defective or it might be a leaking problem. When changing the Ink Pump, take note of the
polarity of the power supply cable and the direction of the arrow head for tubing connections.
Likewise, when the ink priming pressure becomes weak and the negative pressure will go
down below -2.0 reading, the air pump is defective or there might be some leakage somewhere in
the vacuum line system or the 4/2 way valve is malfunctioning. Usually, the vacuum pump can
attain 20-30KPa pressure when you do ink priming. When changing the vacuum pump, you must
take note of the power supply cable and flow direction of air is determined by the arrow head on
the pump.
7.4 Maintenance of Printer Moving Parts
Clean and lubricate all moving parts on a weekly basis. Apply enough light duty grease or oil
whichever is applicable in the contact surfaces. Excessive grease will help accumulate more dirt and
might cause some untimely stoppage of some moving parts.
While excessive oil specially carriage rails and slider bearing might drip on the printed image or
unprinted surfaces and will affect printing quality or ink adhesion on the media. It might be a safety risk if
it will fall on the floor.
7.4.1 Maintenance of X-axis
