METHOD OF MAINTAINING INKJET PRINTHEAD USING NON-CONTACT ROLLER

摘要

A method of maintaining an ink ejection face of an inkjet printhead. The method comprises the steps of: (i) flooding the ink ejection face with ink from nozzles in the printhead; and (ii) rotating a roller adjacent the face, such that flooded ink is transferred from the face onto an outer surface of the roller. The outer surface of the roller does not contact the face during rotation of the roller.
