Nozzle arrangement for an inkjet printhead having an ejection actuator and a refill actuator |
摘要 |
A nozzle arrangement for an inkjet printhead is provided. The nozzle arrangement includes a wafer substrate defining a nozzle chamber and drive circuitry and ink passivation layers defining an inlet to the chamber. An etch stop layer forms a roof layer for the chamber with an ink ejection port defined in the roof layer. The nozzle arrangement also includes an ejection actuator and a refill actuator collectively spanning the inlet, said ejection actuator actuatable via the drive circuitry layer to eject ink from the ejection port, and said refill actuator actuatable via the drive circuitry layer to facilitate refilling of the chamber with ink via the inlet.
