Epson Printhead Technology

It has been many years since Epson’s first color inkjet printer using micro piezo printhead technology was launched in Japan in 1993. That printhead technology is something else. Epson and other inkjet printer manufacturers. Instead of using heat to pressurize the ink particles out of the nozzles in the print head, Epson used the property of quartz to change shape when an electrical pulse is passed through.

With continuous innovations and inventions on the basis of micro piezoelectric printhead technology over the years, Epson creates a series of printer products aimed at a wide range of users, constantly being upgraded to meet the needs of customers. Quality and reasonable price.

The quality of Epson inkjet printers has been confirmed, when this product has won the Most Favorite IT Product Award for 9 consecutive years, voted by TGVT magazine readers.

Epson recently announced a version for a new generation of inkjet printheads – the key component of inkjet technology, allowing markedly improved print quality, speed and reduced product costs.

The key point in improving the printhead technology here is that Epson has successfully implemented a process to fabricate micro piezoelectric components in the form of thin films. thickness is only 1micro (1/1000 mm), compared to current technology is 25 micro.

This technological breakthrough has allowed for increased density of components arranged on the printhead: the number of nozzles has been doubled, from 180 dpi to 360 dpi.

With the new thin film technology, Epson engineers have made the deformation of the micro piezoelectric thin film to a high level, which increases the pressure that pushes the ink out of the nozzle. In addition, Epson also changed the design of some other components in the print head, such as the ink reservoir, allowing for smaller ink particles, more accurate spraying.

With changes in emissive printhead technology, Epson’s new generation inkjet printheads are capable of “shooting” out ink particles that are smaller, denser, and much faster than other printheads. Currently. According to calculations, the print head can “shoot” out ink particles as small as 1/billion liters at a speed of 40,000 times/second.

At the press release, Mr. Norio Niwa – executive vice president of Seiko Epson Corporation, affirmed about the benefits that Epson’s new generation of printhead products will bring, which is speed and print quality. , price and confidence in Epson’s advantages in the inkjet printer market.

According to the plan, mass production of a series of new generation inkjet printheads will be carried out.
