Abstract:
In an example, a print head comprises a nozzle to be activated by a delayed fire pulse that is delayed from an initial fire pulse, a sensor to measure an impedance of the nozzle, and a detector to determine a first time instant following the delayed fire pulse for registering a first impedance measurement by the sensor.
