Abstract

Kyocera realized a trapezoidal actuator unit with one inch width approximately, in which 664 portions of individual unimorph piezoelectric actuators are formed in matrix of 16 rows. This actuator unit has been used for its own piezoelectric ink jet printheads known as KJ4 series, in which four units are used to cover 4.25 inch (108.25 mm) print width.Then, Kyocera has developed a larger actuator unit that covers 4.4 inch (112.35 mm) print width with monolithic rectangular body, in which numbers of individual active portions are arranged. And, it has been adopted for development of new ink jet printhead series.As the first model of the new printhead series, 4.4 inch (112.35 mm), 300 npi ink jet printhead for aqueous ink is introduced. It is equipped with nozzles forming a matrix of 16 rows × 166 columns in 4.4 inch × 1 inch (112.35 mm × 25.4 mm) rectangular region. Each group of adjacent eight nozzle rows belongs to individual channel group, in which nozzles are arranged in 300 npi. And, independent driving conditions in voltage and waveform can be applied to each nozzle group. Practically, this printhead is intended to pack two pieces of 300 npi printheads in 200mm × 36mm × 61mm single body for downsizing and simplification in printer design especially for multi-pass printing applications.
