Abstract

A printhead purging system comprises an ink conduit for supplying ink to a printhead, a hammer head for hammering a wall of a compressible part of the conduit, a spring-loading mechanism for priming the hammer head, and a release mechanism for releasing the primed hammer head. Release of the primed hammer head compresses the ink conduit and results in purging of ink from the printhead.
