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 7):
The drive circuit of  claim 5  wherein:\n the non-jetting pulse generator is configured to increase a number of non-jetting pulses applied to the at least one of the piezoelectric actuators to increase the heat generated by the at least one of the piezoelectric actuators in the region, and to decrease the number of the non-jetting pulses applied to the at least one of the piezoelectric actuators to decrease the heat generated by the piezoelectric actuator in the region.
