摘要:
Some embodiments of the present invention provide an inkjet print head having a housing defining an ink reservoir, a nozzle portion including a nozzle plate defining an ink chamber in fluid communication with the ink reservoir, and forming a fluid flow path between the ink chamber and the ink reservoir, and a substrate coupled to the nozzle plate and having a surface substantially positioned over the nozzle plate. At least one heating element can be coupled to the substrate, and can be positioned adjacent the surface to heat a portion of the ink chamber. In some embodiments, the inkjet print head comprises a control circuit coupled to the at least one heating element for controlling the heating element, and a temperature sense element positioned substantially between the at least one heating element and the control circuit or in at least partially overlapping relationship with the heating element.
