Epson Stylus Pro 7400 - 24" A1
Micro Piezo™ Print Head
A key technology in Epson's worldwide inkjet printing leadership, Epson's Micro Piezo™ print head is designed to extend significantly print head life and deliver the highest image quality possible.
Unlike thermal inkjet technology, Epson's micro piezo technology does not "cook" the ink to eject the ink droplet but instead applies an electric charge to the piezo element. This electrical charge swiftly changes the form of the chamber plate creating a "pull, push, pull" motion which rapidly brings the ink through to the ink chamber and then out through the print head nozzle with superb accuracy onto the media.
Featuring Variable Sized Droplet Technology which achieves the highest possible print speed without sacrificing image quality, Epson's Micro Piezo print heads also provide users with the following key benefits;
- Eliminates the hassle of frequently replacing print heads, allowing users to consistently print for longer, without continuous interruptions
- Epson Micro Piezo Print Heads do not "cook" the ink like thermal inkjet technology, resulting in greater colour consistency print after print
- Epson Micro Piezo Print Heads precisely control the surface of the ink (meniscus) for accurate dot placement, shape and size. Eliminating ink "over-spray" which can cause unwanted smaller droplets to appear on the paper and affect image quality.
