摘要:
An orifice electrode/ink receiving member 11 is attached to an orifice plate 13 that is attached to a recording head module 10. An ink absorbing member 111 is embedded in a lower surface of the orifice electrode/ink receiving member 11. A recording ink droplet 14 ejected through an orifice 12 is deflected as needed by an angled electric field 85 and then impinges on a recording sheet 60 to form a recording dot 70. On the other hand, a refresh ink droplet 15 is deflected by the angled electric field 85 and impinges on the ink absorbing member 111 of the orifice electrode/ink receiving member 11 after flying in a U-turn path. In this configuration, the ink absorbing member 111 provided to the orifice electrode/ink receiving member 11 collects ink, so that there is no need to increase a gap between the recording head module 10 and the recording sheet 60 so much in order to dispose the ink absorbing member 111, 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.
摘要:
With a recording head (200) having a plurality of nozzle holes arranged in a row in a first direction disposed so that the nozzle holes face a recording element (P), the recording element (P) is moved for main scanning in a second direction (B) with respect to the recording head (200). Ink particles jetted from the nozzle holes are charged to a charging level corresponding to the deflection distance of the ink particles, and the charged ink particles are deflected in a direction perpendicular to the main scanning line. In addition, a plurality of ink particles jetted from the plurality of nozzle holes are allowed to strike the same pixel position or a portion in the vicinity thereof to enable multiple-striking to the same pixel position or a portion in the vicinity thereof, thereby easing back-up for failed nozzles and uneven recording.
