Abstract: A jet recovery print process is performed each time before printing a print job, when an inactivity period of non-printing has been exceeded, or during a long print job, where the jets might clog with debris. The jet recovery print process ejects the ink from the inkjets by printing (using the inkjets) a sacrificial page in a jet recovery pattern, while operating the actuators in the inkjets at their maximum voltage rating. The jet recovery pattern is designed to purge all the ink from all the inkjets. Thus, in the jet recovery print process, the controller operates the actuators at their maximum voltage rating so as to provide a higher driving force for the ink to be ejected from the inkjets and thereby make the purge process more effective.
