Abstract:
Devices and method for performing temperature measurements in a printhead. In one embodiment, a printhead includes at least one row of jetting channels configured to jet droplets of a print fluid using piezoelectric actuators. A drive circuit includes an input voltage generator that applies a step voltage to a piezoelectric actuator of a jetting channel, and an output voltage detector that detects an output voltage across the piezoelectric actuator over time in response to the step voltage. The drive circuit also includes a temperature detector that determines a voltage response to the step voltage at the piezoelectric actuator based on the output voltage over time, and determines a temperature measurement for the piezoelectric actuator based on the voltage response of the piezoelectric actuator.

Claim (Index 20):
The printhead of  claim 17  wherein:\n the head driver is configured to determine a capacitance of the piezoelectric actuator based on the voltage response, and to map the capacitance of the piezoelectric actuator to a temperature of the piezoelectric actuator.
