Print head is the crucial part of an inkjet printer, and the most common problem for it is that it will get clogged sometimes. If you don’t solve the clogged problem in time, the print head will be broken quickly. As the old saying goes: You should know what cause the problem, then you can know how to solve the problem.
Why Print heads are clogged?
1. If the print head is exposed to the air for a long period of time, ink can dry up and block the small opening.
2. Foreign objects (ink impurity or dust) can block the opening.
3. Some internet instructions advise users to wipe clean the print head with tissues or paper towels, which may introduce blockage to the print head.
4. An air bubble can temporarily block the opening. Air is naturally dissolved in the ink. Fluctuation of room temperature will change the air concentration and thus form air bubbles.Besides,changing cartridges also introduces air into the system.
How to solve it ?
1. Clean it with water
For sublimation ink manufacture, the ink must be able to dissolve in the medium in which it is made. So many ink manufactures also produce cleaning solution. But generally speaking, the water performs as well as cleaning solution.
You can use water to dissolve or soften the blockage. Sit the print head in a bowl of water for few hours. Most print heads can be submerged underwater as long as you dry up the contact points before inserting back in the printer.
2. Increase the temperature
Since different substances are made from different atoms, increased temperature will affect their dissolving to different extents.herefore, you should use hot water when you soak the print head. The temperature can be somewhere between 90 °F - 120 °F.
3. Try to push the ink out
Drill a hole on the cartridge and use syringe to push ink downward, then wash the print head under hot running water.
4. The machine
If you think manual cleaning is too troublesome, you can invest a machine to help you. For example, you can buy a steaming machine, it will increases the temperature and the steam which can keep printer head moisturized. Or you can buy a ultrasonic cleaner like the one used in cleaning jewelry or medical equipment, it will help you clean your print heads quickly.
