Method of controlling drop directionality from inkjet nozzle using multiple independently-actuable roof paddles
Abstract:
A method of controlling a direction of droplet ejection from an inkjet nozzle having a plurality of moveable paddles, the method includes the steps of: (i) actuating a first thermal bend actuator via respective first drive circuitry such that a respective first paddle bends towards a floor of the nozzle chamber; (ii) actuating a second thermal bend actuator via respective second drive circuitry such that a respective second paddle bends towards a floor of the nozzle chamber; and (iii) thereby ejecting a droplet of ink. Actuation of the first and second thermal bend actuators is independently controlled via the first and second drive circuitry so as to control the direction of droplet ejection.
