How does the Piezo inkjet print heads complete the ink jet process?

      Every inkjet printer in the market has one thing in common: print head. Small and large inkjet printers have print heads that store ink on all types of media.A print head is "usually a movable part of a printer that contains the printing elements." The print head applies the ink to the paper.Before print heads came around, prints were made on printing presses that made direct contact with the media. The process was often messy and expensive and the presses were very large.The appearance of the printing head reduces the printing cost and controls the ink to be sprayed into paper or other medium in order to produce the desired image.

    Piezo inkjet print heads are currently used in Epson inkjet printers including both their small format and large format printers. Piezo print heads don't use heat to force ink out of the nozzle. Instead, Piezo print heads feature a layer - usually a thin film – that is exposed to an electric charge that causes the film to vibrate. The vibration causes the film top flex and bend, building up pressure and forcing the ink from the nozzle onto the paper. Being able to quickly vibrate and flex the film allows for more precise control of how fast the ink gets pushed out of the nozzle.
    Piezo print heads are compatible with a wide range of inks since they don't use heat in the

printing process. Compatible inks include water-based, oil, Eco-solvent and solvent based inks. A typical Piezo print head has 720 nozzles per color which can require multiple passes and may slow down printing speed. Piezo print heads can control the size of the ink droplet, which can increase print resolution in some applications when smaller droplet sizes are used. Piezo print heads have a longer lifespan and are designed to last for the life of the printer (generally around 3-5 years). Should the Piezo print head need to replaced, it is more expensive and requires an authorized service technician.
