Only Epson has micro-piezoelectric?

Not only does Epson have a miniature piezoelectric printer, but HP also has this technology. Piezoelectric crystals are used behind the miniature ink container of the print head. When the crystal is electrified, it will bounce inward. When the current is interrupted, the crystal will bounce back to its original position, and at the same time a drop of ink will be ejected through the nozzle; When the current is restored again, the crystal extends outward again, thus entering the ready state of ejecting the next drop of ink.

Epson has the most advanced patent of micro-piezoelectric printing technology at present, and the ink-bin printing products born with this technology make the industry sit up and take notice with an annual growth rate of 50%; On the other hand, because the whole brand stopped producing laser printing products, it is not uncommon for Epson to attack other brands' laser printing products with inkjet printing products, which has been seriously criticized by the industry.

Product characteristics

Unlike thermal foaming printing technology, which uses the ink in front of the nozzle to heat and finally eject ink droplets, the micro-piezoelectric printing technology developed by Epson uses physical means to push ink droplets out of the nozzle. Ink is also sprayed on the printing medium. Why is the micro-piezoelectric printing technology called inkjet 1.5 generation technology?

This is mainly because the heated part of the product ink using thermal foaming printing technology evaporates, and the nozzle will deposit, which eventually leads to the nozzle blockage and unusable. Because the micro-piezoelectric printing technology adopts physical propulsion, the probability of this problem is effectively alleviated.
