Abstract: Protrusions are positioned on the inner surfaces of a channel within a printhead body or member to control the size and location of bubble formation. An inkjet printhead includes a member having a first opening and a second opening to enable melted ink to enter the channel at the first opening and flow through the channel to the second opening. At least one protrusion extends from the member into the channel to position a portion of the protrusion into melted ink in the channel to form a dominant stress concentration in the melted ink.

Abstract: An inkjet printing system, including an inlet in a print head to receive ink from an ink supply, a plurality of nozzles to eject ink in the print head, an ink pressure sensor disposed in an ink path, the ink pressure sensor configured to determine an ink pressure of the ink in the print head and output a signal indicating the ink pressure, and a controller in the print head configured to receive and process the signal indicating the ink pressure from the ink pressure sensor. The inkjet printing system may also include a memory to store an ink pressure and time profile. The controller may also output a signal to stop ejecting ink from the plurality of nozzles when the ink pressure is either below a negative threshold or above a positive threshold.

Abstract: A print head includes a substrate having a hole, a circuit on the substrate, the circuit having traces and a hole corresponding to the hole in the substrate, the hole forming a fluid path, and a raised structure on the substrate around the fluid path, the raised structure positioned to seal the circuit from the fluid path.
