What are the main causes of nozzle blockage and damage?

1. When the printer is not used for a long time, the water in the ink nozzle evaporates and becomes a dry solid, which is blocked in the nozzle;

2. The inks of different manufacturers and brands react chemically after mixing, and are neutralized due to different colloidal charges, forming precipitation and blocking spray;

3. Due to the use environment and other factors, the ink contains or is mixed with impurities, dust, etc. , it will also cause nozzle blockage and damage;

These are roughly the problems. Of course, other special circumstances are not excluded! See for yourself.
