6.2 Filling ink
After installed the printheads, check the ink circuit and connection again,
and then make sure that the filling ink operation is not carried out until it is
correct.
Turn off the spray function in the software and lower the negative pressure to-1.2
kpa.so that the negative pressure after filling ink is larger than the protection.
Pour the ink into the main tank accordingly and make sure the
ink pump power line is connected.
Click "reset" in the software.
When the ink supply lasts 15 seconds and the secondary cartridge is not
filled, the system will automatically alarm three beeps. After the ink is
finished, set the negative pressure to the normal value of - 4.5 kpa.
Usually 3-4-times "reset" can be filled with ink.
6.3 Air exhausting of the printhead
Air exhausting operation is required when printhead is firstly filled with
ink,in order to eliminate the air bubbles inside the printhead, so that the ink
can be supplied continuously while the printhead is jetting, thus avoiding the
missing nozzle during the printing.
This method also can be used in the subsequent nozzle maintenance
operation.
Turn off spray cleaning function.
Lower the negative pressure to -1.5 kpa, and open the printhead that needs
exhaust, press the corresponding pressure switch at the same time.
