Right now, two types of the printhead are available. Every type of printhead is using different spraying methods to spread the ink. Two printhead types are thermal and piezo. Both printheads have different ways to move the ink.

After knowing about what is a printhead on a printer? read the two types below.

1. Piezo inkjet printheads

You can find this type of printhead in many Epson inkjet printers. The large format and small format printers by Epson all have this piezo printhead. Piezo printhead is not using heat to spray the ink out of the printer’s nozzle. There is a layer feature in this printhead that looks like a thin film.

This layer gets an electric charge that makes the film vibrate. And then the vibration makes the film top bend and flex, building up the pressure before forcing the ink to the paper from the nozzle. Piezo printhead has more precise control in pushing the ink out of the nozzle quickly.

It is because of the quick vibration and its ability to flex the film. This printhead type is compatible with various types of ink because piezo doesn’t use heat during the printing process.

The Printhead

Printheads are working by getting instructions from your printer as images or text. They will also receive ink from your printers cartridge before finally transferring the ink to your paper media. Unlike ink cartridges, you don’t have to replace the printheads every time you have to replace the cartridges.

You have to replace the printheads only when your printer’s print quality starts to deteriorate. However, before replacing the printhead, you need to try solving the printhead problem by cleaning the printhead. If cleaning your printhead doesn’t help, you need to replace it to fix the problem.

The Importance of Printheads

Ink cartridges are important since they work as storage to keep your ink in the printer. But printhead is also crucial since it helps your printer to write the ink to the paper media. Without printhead, your printer will not be able to spray the inks to the paper and you won’t get the documents you need.
