Method and apparatus for cleaning an ink jet printhead

Abstract

An ink jet printhead having a nozzle face in which at least one printhead nozzle is formed is cleaned by disposing a suction nozzle in front of the nozzle face, so that it forms a small gap therewith, and sucking ink out of the prinhead nozzle. The ink is caused to spread or flow in the gap in a direction parallel to the nozzle face so as to clean the nozzle face.
