Printhead IC with actuator movement parallel to ink inlet flow
First Claim
1. An inkjet printhead integrated circuit (IC) for a printer, the printhead IC comprising:
- a wafer substrate defining a plurality of ink inlets;
a plurality of nozzle structures formed on the substrate for communication with each of the ink inlets respectively, each nozzle structure having a chamber, an ejection nozzle in fluid communication with the chamber, and an ejection member for acting on ink within the chamber;
a plurality of actuators attached to the substrate for moving each of the ejection members respectively, the movement being substantially parallel to the ink inlet flow direction;
such that,ink is ejected through the ejection nozzle upon activation of the actuator corresponding to that nozzle structure.

Abstract
An inkjet printhead IC is fabricated using a wafer substrate that defines a plurality of ink inlet channels. A plurality of nozzle structures fabricated on the substrate to define nozzle chambers are in fluid communication with the ink inlet channels and an ink ejection nozzle in fluid communication with each nozzle chamber. Each nozzle structure has a chamber, an ejection nozzle in fluid communication with the chamber, and an ejection member for acting on ink within the chamber. A plurality of actuators attached to the substrate move each of the ejection members respectively, the movement being substantially parallel to the ink inlet flow direction; such that, ink is ejected through the ejection nozzle upon activation of the actuator corresponding to that nozzle structure.
