Abstract:
A system for monitoring ink flow is disclosed. In one embodiment, the system includes a printhead configured to perform a priming event, a heating element, a sensor configured to measure the temperature of a printhead die at a plurality of times, and a processor configured to determine the success of a priming event by comparing an actual cooling rate to a threshold cooling rate.
