Abstract
A method of determining whether a flow path is ready for ejection includes supplying liquid to the flow path, which includes a pumping chamber and a nozzle, after supplying fluid to the flow path, applying energy to an actuator adjacent to the pumping chamber, measuring an electrical characteristic of the actuator to obtain a measured value, and comparing the measured value to a threshold value to determine if the flow path is ready for ejection.
