Zusammenfassung:	A print head has an ink source to supply and receive ink, a first channel to receive ink from the ink source, a second channel to return ink to the ink source, and a manifold structure connected to the two channels to receive ink from the first channel and return ink to the second channel. A method of operating a print head includes providing ink from an ink source at a first pressure through a first channel, routing the ink through an inlet port of at least one single jet, moving the ink through the single jet to an outlet port of the single jet, routing the ink from the outlet port of the single jet, directing the ink to a second channel, and returning ink through the second channel to the ink source at a second pressure.
