Reason 1: Secondary ink cartridge failure
The vent of the secondary ink cartridge is blocked, and no air can enter. The internal pressure is too high and the ink cannot be discharged. If the vent is blocked, you need to reopen the vent to make the air intake smooth. You can wrap the secondary ink cartridge with soft paper 2 times at the flat line connection to absorb the residual ink.
Reason 3: Nozzle blockage
The nozzle is blocked, pause the equipment, reset to the X-axis origin, raise the nozzle carriage by 20 cm, press the ink pressing key, observe the negative pressure fluctuation value, and pause when it reaches 10. Observe that the water droplets of ink pressing are in a continuous state and continue printing.
Reason 3: The ink in the ink cartridge is used up or below the pressure line
The ink in the ink cartridge is used up or below the pressure line. You need to open the ink tube cover to check whether the ink is exhausted. When pouring new ink, you need to pour it slowly in a backlight environment to avoid drying the ink under strong light.
Reason 4: Piezoelectric crystal damage
The piezoelectric crystal inside the nozzle is damaged due to excessive voltage, ink infiltration, etc., and a new nozzle needs to be replaced.
Reason 5: Ink supply pipeline blockage
The ink supply pipeline is blocked, and the nozzle switch needs to be turned off. Use a needle tube to press air to clear the impurities in the ink tube so that the ink can flow smoothly.
Reason 6: Metal float failure
The metal float is a magnetic component in the secondary ink cartridge, which is used to control the inkjet of the nozzle. If a fault occurs, the ink will not be ejected and the ink will be cut off. You need to open the ink cartridge cover and use a needle to wave it to restore it to normal.
