Abstract
Printheads that jet print fluids. In an embodiment, a printhead comprises a plurality of jetting channels, where each jetting channel includes a diaphragm, a pressure chamber, and a nozzle configured to jet a print fluid. The printhead further comprises a manifold fluidly coupled to the jetting channels, where each jetting channel includes a channel fluid passage that fluidly couples the pressure chamber to the manifold. The printhead further comprises an intra-channel fluid mixer disposed at the channel fluid passage, and configured to cause a circular rotation of the print fluid that flows between the pressure chamber and the manifold through the channel fluid passage.
