Analysis of Reasons Why Printing Machinery Nozzles Come Out of Ink

What are the reasons why the printer's nozzle is not inked and is easily blocked? If this situation continues, it will definitely affect the quality of the picture. Therefore, here we talk about the reasons why the printing heads do not print:

1. The ink is easy to evaporate, volatile solidifies out of the solid, leaving a part of the ink around, and is easy to clean outside the nozzle. This is why we often clean the nozzle.

2. Piezoelectric crystals are damaged. It may be normal for less than one year in a factory with a lot of printing work.

3, piezoelectric crystal fatigue damage, when the amount of ink is large, it is clear that the need to replace the nozzle.

4, the ink does not flow in the nozzle for a long time, the smaller the cross-sectional area of ​​the ink flow will also cause the nozzle no ink phenomenon.

5, the driver circuit failure, may affect the voltage of the drive nozzle, causing the nozzle does not come out of ink.

6, frequent replacement of ink, will affect the inkjet status of the nozzle.

7, the use of environmental temperature and humidity of the machine, high and low temperature affect the viscosity of the ink, often mistaken for "head clogging."
