摘要： Printheads and manifolds within printheads. In one embodiment, a method comprises determining a resonant frequency of jetting channels for a printhead, and selecting a target length for a manifold fluidly coupled to the jetting channels such that resonant frequencies of the manifold differ from the resonant frequency of the jetting channels by a threshold amount.

摘要： An inkjet head that is able to circulate ink. The inkjet head includes a diaphragm plate, a first restrictor plate, one or more chamber plates, a second restrictor plate, and an orifice plate. The orifice plate forms a plurality of nozzles. The chamber plates form a plurality of chambers corresponding with the nozzles, and also form a return manifold for receiving ink from the chambers when circulating the ink through the inkjet head. The diaphragm plate forms a diaphragm that seals the chambers. The first restrictor plate controls a flow of ink between the chambers and the return manifold to circulate the ink through the inkjet head. The second restrictor plate controls the flow of ink between a supply manifold and the chambers.
