The design features a channel for receiving ink, which includes a recirculation portion that allows for ink to be received during non-jetting events. Additionally, the print head incorporates a first manifold structured to supply ink to the channel and a second manifold to receive ink from the recirculation portion. This innovative flow design enhances the efficiency of ink usage during printing processes.

Another patent by Tence also revolves around single jet recirculation in an inkjet print head. This design includes multiple single jet elements, each with an aperture for ink ejection and a channel for receiving ink. The print head is equipped with a first manifold to supply ink and a series of recirculation paths that receive ink during both jetting and non-jetting events. The recirculation paths are ingeniously formed by half-etching steel plates that are part of the single jet elements. This design allows for improved ink flow from the first manifold to the second manifold through the single jet elements during non-jetting events.
