How to open a clogged cartridge.
The easiest solution to the problem of clogging as a result of ink drying as a result of not using inkjet or inkjet printers for a while is to use an ultrasonic cleaner.
When you put a suitable solvent solvent or solvent chemical suitable for the type of ink into the ultrasonic cleaner device chamber, put the cartridge into the chamber and turn on the ultrasonic cleaner device, you can immediately observe that the ink begins to dissolve.
If you are going to use solvent based solvents, you should choose an ultrasonic cleaner with metal casing.
