Abstract
A printhead assembly includes ink ejection devices having nozzles, and processing electronics in communication with the ink ejection devices. The processing electronics implement logic to receive nozzle data for controlling the ink ejection devices, receive error detection data associated with the nozzle data, detect errors associated with the nozzle data using the error detection data, and generate fault data for the detected errors.
