  • Patent number: 9676190
    Abstract: A print head die may include a substrate, an electrical connector and at least three liquid feed slots. The electrical connector is on a first side of the substrate and extends along the major dimension of the substrate. The electrical connector is connectable directly to an electrical interconnect to connect the print head die to a controller. The at least three liquid feed slots are formed in the substrate and extend along the major dimension of the substrate. Wherein at least one and less than all of the at least three liquid feed slots has an associated temperature sensor connected to the electrical connector.

  • Patent number: 9676192
    Abstract: A printbar module and method of forming the same are described. In an example, a printbar module includes a printed circuit board (PCB), a plurality of printhead die slivers, and a manifold. The printhead die slivers are embedded in molding and attached to the PCB. The molding has a plurality of slots in fluidic communication with fluid feed holes of the printhead die slivers. The manifold is in direct fluidic communication with the slots to supply fluid thereto.
