FUJIFILM Group’s Inkjet Printhead and Technology

1 FUJIFILM Group's Inkjet Printhead and Technology Yoshinori KATO . Abstract This paper introduces FUJIFILM Dimatix's Inkjet Printhead products and technologies. The broad product range includes devices with various native drop masses, print resolutions, and nozzle plate materials. Especially, stable jetting is expected with the new StarFire Printhead which features a unique ink recirculation structure that maintains the ink inside the nozzle in the best condition. In addition, the world's most advanced Printhead SAMBA' uses not only the ink recirculation but also MEMS Technology , high-efficiency sputtered PZT actuator, and durable non-wet film on the nozzle plate to achieve precise and stable printing with a high resolution of 1200 dpi. 1 ..
