1. An ink ejection nozzle comprising:
- an ink reservoir with an oscillator configured to oscillate ink pressure in the reservoir;
a wafer assembly defining an ink supply channel in fluid communication with the ink reservoir;
a nozzle chamber structure on the wafer assembly and defining a nozzle chamber in fluid communication with the ink supply channel, and an ink ejection port in fluid communication with the nozzle chamber; and
a shutter positioned in the nozzle chamber and configured to shut the ink ejection port to the ejection of ink from the nozzle chamber.

Abstract
An ink ejection nozzle has an ink reservoir with an oscillator configured to oscillate ink pressure in the reservoir. A wafer assembly defines an ink supply channel in fluid communication with the ink reservoir. A nozzle chamber structure on the wafer assembly defines a nozzle chamber in fluid communication with the ink supply channel. An ink ejection port is in fluid communication with the nozzle chamber. A shutter is positioned in the nozzle chamber and is configured to shut the ink ejection port to the ejection of ink from the nozzle chamber.
