PRINTHEADS WITH SENSOR PLATE IMPEDANCE MEASUREMENT
摘要
In an implementation, a printhead includes a nozzle and a fluid channel. A sensor plate is located within the fluid channel. An impedance measurement circuit is coupled to the sensor plate to measure impedance of fluid within the channel during a fluid movement event that moves fluid past the sensor plate.
