The sealing of the ink supply system of the printer is very important. Many of the problems that usually occur nozzle missing are not related to the sealing work. Let's talk about it specifically.

Air leakage in ink cartridges, damper, ink tubes, ink tube and nozzle linking columns will cause nozzle missing during printing. The piezoelectric printer uses micro piezoelectric inkjet technology, and the entire ink supply system is closely connected to ensure the tightness between the ink cartridge, the ink supply tube and the ink cartridge of the nozzle, no air and air leakage. If the air leakage occur, it will easily cause the piezoelectric printer have the situation of nozzle missing, the ink supply cannot be pumped normally, and ink return in the damper. There is always air in the ink tube and the ink cannot enter the damper and so on. If there is nozzle missing and there are still problems after multiple cleanings, you can consider whether the ink path is leaking, and then check the leaking parts in turn.

In summary, in the process of using the piezoelectric printer, it is necessary to pay attention to the sealing of the ink supply system of it, and also to provide more maintenance for the ink supply system.
