Document Type and Number:
WIPO Patent Application WO/2016/163105
Kind Code:
A1
Abstract:
A fluid printhead (10) including at least one fluid ejection element (100). The fluid ejection element (100) includes a fluid chamber (102), a throat portion through which fluid is provided to the fluid chamber (102), and a heating element (104) disposed within the fluid chamber (102). The fluid ejection element (100) also includes a printhead condition detection system (120). The printhead condition detection system (120) includes a first electrode (106) at least a portion of which is disposed within the fluid chamber (102), the first electrode (106) configured to receive a step voltage, a second electrode (110) disposed within the throat portion, and a sense circuit (112) electrically connected to the second electrode (110) that generates an output based on the application of the step voltage to the first electrode (106) as an indication of printhead condition.
