摘要： A method for manufacturing an inkjet recording head includes an ejecting step, a measuring step, dividing step and applying step. The ejecting step ejects test ink droplets and print ink droplets from nozzles. The measuring step measures ejection results of the test ink droplets. The dividing step divides a plurality of nozzles into a plurality of groups based on the ejection results. The applying step applies a group-based polarizing voltage determined for each group to the piezoelectric elements belonging to a corresponding group to polarize the piezoelectric elements so that ejection results of the print ink droplets fall in a predetermined range.

摘要： A print head for ink jet printer having a reduced length in a main scanning direction and an elongated length in an auxiliary scanning direction perpendicular to the main scanning direction. A plurality of linear print head modules are arrayed in the auxiliary scanning direction, and each linear print head module extends in a slanting direction with respect to the main scanning direction by a predetermined angle. Further, each linear print head module has a width in a direction perpendicular to its extending direction. The slanting angle and the width determine scanning pitch extending in the auxiliary scanning direction and can reduces the length of the print head in the main scanning direction.

摘要： When an refresh ink droplet ejected from a nozzle and deflected by an inclined electric field impinges on a orifice electrode/ink receiving member, electric charge is discharged from the refresh ink droplet, thereby an electric current is generated. A current-voltage converter/amplifier detects the electric current and outputs a detection signal. A defective-condition determining circuit determines an ejection condition of a nozzle element based on voltage value of the detection signal.

摘要： A recording head 200 has a plurality of nozzle orifices aligned in a row extending in a first direction. The recording head 200 is arranged with the nozzle orifices in confrontation with a recording medium P. The recording medium P is moved in a second direction B with respect to the recording head 200. Also, ink droplets ejected from the nozzle orifices are charged to a charged amount that corresponds to deflection amount of the ink droplets. The charged ink droplets are deflected in a direction perpendicular to a main scanning line. The plurality of ink droplets ejected from the plurality of nozzle orifices impinge on the same pixel position or at a nearby position so that it is possible to impinge multiple droplets at the same pixel position or a nearby position. As a result, it is possible to back up broken nozzles and to reduce recording distortion.

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.
