Abstract:
A fluid printhead including at least one fluid ejection element. The fluid ejection element includes a fluid chamber, a throat portion through which fluid is provided to the fluid chamber, and a heater element disposed within the fluid chamber. The fluid ejection element also includes a printhead condition detection system. The printhead condition detection system includes a first electrode at least a portion of which is disposed within the fluid chamber, the first electrode configured to receive a step voltage, a second electrode disposed within the throat portion, and a sense circuit electrically connected to the second electrode that generates an output based on the application of the step voltage to the first electrode as an indication of printhead condition.

Claim (Index 1):
A fluid printhead, comprising:\n a plurality of fluid ejection elements, each fluid ejection element comprising:\n a fluid chamber; and \n a heater element disposed within the fluid chamber; and \n a printhead condition detection element comprising:\n a common first electrode formed by a cavitation layer that is common to each fluid chamber, the common first electrode being configured to receive a step voltage; \n a plurality of sense circuits each electrically connected to a corresponding one of a plurality of second electrodes respectively coupled to the plurality of fluid ejection elements for outputting an indication of printhead condition based on the application of the step voltage to the common first electrode, each sense circuit outputting a digital low output upon detecting an absence of fluid in at least a portion of each respective fluid chamber.
