Reason one:
Ink cartridges in the ink is used up or below the pressure line, you need to open the ink tube cover, check whether the ink is exhausted. When pouring new ink, you need to pour it slowly in a backlit environment to avoid drying the ink caused by strong light.
Reason 2:
The vent port of the secondary cartridge is blocked, so it can't get air in, and the internal pressure is too high for the ink to come out. If the air vent is blocked, you need to reopen the air vent to make the air inlet smooth. In the secondary cartridge in the flat line link, with soft paper wrapped around 2 circles, do residual ink adsorption.
Reason 3:
Nozzle clogging, pause the device, reset to the X-axis origin, the nozzle car raised 5 centimeters, press the ink key, observe the negative pressure fluctuation value, reach 5.0 when paused to observe the ink pressure of the beads of water is a coherent state can continue to print.
Reason 4:
Piezoelectric crystal damage, the piezoelectric crystal inside the printhead due to excessive voltage, ink infiltration and other circumstances resulting in damage, need to replace the new printhead.
Cause five
The ink supply pipe is blocked, you need to turn off the printhead switch, use the syringe to press the air, unclogging the impurities in the ink pipe, so that it can be a smooth flow of ink.
Reason six
Metal buoy failure, metal buoy in the secondary cartridge, is a magnetic component, used to control the printhead inkjet, such as failure, the inkjet ink will not be out of the ink, will be broken. Need to open the cartridge cover, fluctuate down with a needle, so that it returns to normal.
