Zusammenfassung:An inkjet print head including a plurality of single jet elements. Each single jet element includes an aperture configured to eject ink during a jetting event, a channel for receiving ink. The inkjet print head also includes a first manifold structured to supply ink to the channel; and a plurality of recirculation paths. Each recirculation path configured to receive ink during the jetting event and a non-jetting event. Each recirculation path includes a recirculation channel connected to the channel for receiving ink, the recirculation channel is formed by half-etching one of the steel plates that forms part of the each of the single jet elements and the recirculation paths, and a second manifold structured to receive ink from the recirculation channel. The ink flows from the first manifold to the second manifold through each of the plurality of single jet elements and the recirculation paths during a non-jetting event. 本发明涉及种包括多个单喷射元件的喷墨打印头。每个单喷射元件包括构造成在喷射事件期间喷射油墨的孔和用于接收油墨的通道。喷墨打印头还包括构造成向通道供给油墨的第歧管以及多个再循环路径。
