Abstract

A static electricity-actuated inkjet head, SEA inkjet head, has been developed for inkjet point-of-sale, or ‘POS,’ printers. This type of inkjet technology is different from the piezoelectric type. SEA inkjet technology makes possible smaller sized inkjet POS printers with faster print speeds, higher resolution graphics, more precise barcode, 2-color printing, and higher reliability than heretofore.The SEA inkjet head is fabricated entirely by Micro-Electro-Mechanical Systems (MEMS) processes and its driving voltage is typically 26.5V. The electrostatic actuator comprises a silicon pressure plate and a corresponding transparent electrode parallel to the pressure plate. They are assembled precisely to keep the gap there between to be 180 nm. The ink firing of the SEA inkjet head is responsive to at least to 16 kHz. The durability of the actuator has been confirmed to be more than 10 billion actuations.In this paper SEA inkjet technology is introduced. And its structure, ink ejection mechanism, fabrication process, driving method and characterizations are demonstrated.
