Abstract
A liquid drop ejector comprising a jet stack, thin film or thick film heaters formed on the surface of the jet stack, and at least one thin film or thick film temperature sensor operative to provide feedback temperature control for the thin film or thick film heater elements is provided. In one form, the liquid drop ejector also has the thin film or thick film heater elements grouped in segments that are operative to be individually controlled. In addition, in another form, the signal lines provided to the liquid drop ejector are patterned to allow for more uniform resistance over the span of the liquid drop ejector.
