摘要： A method that provides printhead swath height measurement and compensation includes the steps of establishing a nominal printhead swath height to be associated with printheads of a particular type; printing a swath using a first printhead of the particular type; measuring a printhead swath height of the first printhead; determining a difference between the measured printhead swath height of the first printhead and the nominal printhead swath height; generating a printhead swath height correction value based on the difference; and storing the printhead swath height correction value in a printhead memory associated with the first printhead.

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.
