FLUID CIRCULATION WITHIN CHAMBER

摘要

A printhead or other fluid handling device includes a firing chamber. Plural actuators are configured to cause fluid to be drawn into or ejected from the firing chamber. The actuators can also cause fluid to circulate within the firing chamber without appreciable fluid flow out of or into the firing chamber. Electronic signals independently control the respective actuators in accordance with various operating modes. Problems associated with fluid drying, separation of constituents within the fluid and other phenomenon are reduced or eliminated accordingly.
