ABSTRACT:
An ejection arrangement is provided for a printhead nozzle. The arrangement has a chamber having an inlet defined by edge portions of a first side of the chamber and an ejection port defined in a second side of the chamber, and an ejection member located in the chamber between the edge portions. The ejection member is operable to cause ejection of fluid in the chamber through the ejection port and subsequent refill of fluid into the chamber through the inlet. The edge portions are configured to reduce fluid flow through a space between the edge portions and the ejection member during ejection.
