Abstract: Printheads and methods of operation. In one embodiment, a printhead includes a plurality of jetting channels comprising first jetting channels configured to jet a first print fluid and second jetting channels configured to jet a second print fluid, and a driver circuit communicatively coupled to actuators of the jetting channels. The driver circuit receives a drive waveform comprising non-jetting pulses and jetting pulses, and gating signals comprising a first active gating signal designated for jetting the first print fluid, and a second active gating signal designated for jetting the second print fluid. The driver circuit selectively applies the non-jetting pulses and the jetting pulses to actuators of the first jetting channels based on the first active gating signal to jet the first print fluid, and selectively applies the jetting pulses to actuators of the second jetting channels based on the second active gating signal to jet the second print fluid.

Abstract: 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.

Abstract: Apparatus and method for providing a print fluid to a flow-through printhead. The printhead has a row of jetting channels configured to jet droplets of a print fluid, a supply manifold fluidly coupled to the row of jetting channels, and a return manifold fluidly coupled to the row of jetting channels. A first reservoir is fluidly coupled to the supply manifold, and a second reservoir is fluidly coupled to the return manifold. The first reservoir and the second reservoir are fluidly isolated except through the printhead.

Abstract: A carriage assembly for a printer that reciprocates along scan directions. The carriage assembly includes at least one printhead having a row of jetting channels for ejecting a print fluid, and reservoirs mounted on the carriage assembly that each supply the print fluid to the printhead. At least one of reservoirs is mounted on the carriage assembly to be offset from the row of jetting channels.

Abstract: 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.

Abstract: In a communications apparatus, a communication controller transmits and receives signals on any of plural channels. A channel switching controller is responsive to channel switching information selectively defining plural reception-waiting periods using the channels to alter a channel to be used by the communication controller. A neighboring node channel controller exchanges channel switching information with other nodes to manage the channel switching information received from the other nodes. When transmitting transmission signals, a transmission controller refers to the channel switching information of the other nodes, and controls repetitive transmission of the transmission signals on the channel thus searched for.

Abstract: A damper obtaining damping force by the frictional resistance imparted by the viscosity of the magnetic viscous fluid is disclosed. The damper is provided with a seal not only on one (lower side) of the axial outer sides of the yoke but also on the other (upper side) of the axial outer sides of the yoke to trap the magnetic viscous fluid within the magnetic viscous fluid filling portion at both axial outer sides of magnetic viscous fluid filling portion. Because the leakage of the magnetic viscous fluid can be prevented, no air is introduced into the magnetic viscous fluid filling portion, to allow the density of the magnetic viscous fluid within magnetic viscous fluid filling portion to be maintained at a favorable level and prevent degradation of damping force.
