Abstract
An orifice electrode/ink receiving member is attached to an orifice plate that is attached to a recording head module . An ink absorbing member is embedded in a lower surface of the orifice electrode/ink receiving member . A recording ink droplet ejected through an orifice is deflected as needed by an angled electric field and then impinges on a recording sheet to form a recording dot . On the other hand, a refresh ink droplet is deflected by the angled electric field and impinges on the ink absorbing member of the orifice electrode/ink receiving member after flying in a U-turn path. In this configuration, the ink absorbing member provided to the orifice electrode/ink receiving member collects ink, so that there is no need to increase a gap between the recording head module and the recording sheet so much in order to dispose the ink absorbing member , preventing decrease in recording precision and paper jam. Also, it is possible to perform the ink refresh operation using a minimum amount of ink anytime needed without stopping recording operations.
