摘要： A high resolution printhead for an ink jet printer. The printhead includes a semiconductor substrate containing at least one ink feed edge and a plurality of ink ejection actuators spaced a distance from the ink feed edge. Each of the ink ejection actuators has an aspect ratio ranging from about 1.5:1 to about 6:1. A nozzle plate is attached to the semiconductor substrate. The nozzle plate contains a plurality of nozzle holes, ink chambers and ink channels laser ablated in the nozzle plate corresponding to the plurality of ink ejection actuators. Adjacent nozzle holes are spaced apart with a pitch ranging from about 600 to about 1200 dpi. The distance from the ink feed edge is substantially the same for each of the ink ejection actuators.

摘要： A method of making flow feature structures for a micro-fluid ejection head. The method includes the steps of laser ablating a nozzle plate material to provide an elongate fluid chamber and fluid supply channel therein for connecting the fluid chamber with a fluid supply. The fluid chamber has a first length and a first width. An elongate nozzle hole is laser ablated in the nozzle plate material co-axial with the fluid chamber. The nozzle hole has entrance dimensions having a longitudinal axis dimension and a transverse axis dimension such that the longitudinal axis dimension is from about 1.1 to about 4.0 times the transverse axis dimension.
