Unlike other printer manufacturers that widely use thermal foaming technology, Epson uses micro piezoelectric inkjet design as its core technology. After years of development and improvement, the current micro-piezo inkjet technology has become Epson's housekeeper, and its products have higher durability and reliability on the basis of continuously increasing the printing speed.
Epson Micro Piezo Printhead
Epson micro piezoelectric printhead structure
Epson controls the deformation of piezoelectric crystals through its unique micro piezoelectric printing technology, precisely controls the size of ink droplets, and ensures excellent printing accuracy. No heating is required during the inkjet process, so the chemical composition of the ink will not change, ensuring the high frequency of single nozzle operation and stability in printing. The newly improved micro piezoelectric print head has more nozzles, and each color has reached 180 print nozzles, which increases the printable area of ​​the print head each time it moves, and directly increases the printing speed.
How Epson Micro Piezo Technology Works
Using pulsed electrical signals to precisely control the size of ink droplets
Epson Micro Piezo Print Head VSDT Technology
Epson's "Century Rainbow" bright pigment ink controls the piezoelectric crystal through different pulses according to the type of image and the printing medium used, thereby generating several different sizes of ink droplets. The newly developed micro piezoelectric print head improves the VSDT technology. Thus, high-density Epson "Century Rainbow" bright pigment ink can be sprayed. This technology not only improves the image quality, but also increases the printing speed.
Because the pressure in the micro piezoelectric inkjet head is small, the nozzle is actually replaced by a piezoelectric ceramic wafer, so the cost of the inkjet printhead made by the micro piezoelectric technology is high. In order to avoid the cost increase caused by replacing the nozzle of the ink cartridge when the ink is used up, the nozzle and the ink cartridge are a separate structure in the micro piezoelectric ink head, one nozzle can support multiple ink cartridges, and only need to replace the ink cartridge when replacing the ink. There is no need to replace the print head, so you can save part of the cost of printing supplies.
