1. Immersion method
Scope of application: less obstructed
Necessary tools: 95% alcohol, a clean cup and a metal container with smooth bottom
Working principle: Use medium strength organic solvent to dissolve ink particles one by one. Note that 95% organic solvent alcohol must be used, otherwise it will be counterproductive.
2. Pressure cleaning method
Scope of application: severely obstructed
Necessary tools: 95% alcohol, a clean cup, a disposable syringe, and a disposable infusion set.
Working principle: use the pressure generated by the siphon effect of the syringe to inject alcohol, an organic solvent, into the print head, so as to achieve the function of cleaning the dry ink head.
3. Distilled water cleaning method
Scope of application: seriously obstructed
Necessary tools: an empty decoded ink cartridge, a disposable syringe and a bottle of medical distilled water (also can be replaced by pure water).
Working principle: similar to that of pressure cleaning method, it is unnecessary to repeat them here.
4. Ultrasonic instrument cleaning method
Scope of application: the most serious obstruction
Working principle.
