INKJET RECORDING APPARATUS AND METHOD OF INVESTIGATING EJECTION FAILURE DETERMINATION PERFORMANCE

摘要

PROBLEM TO BE SOLVED: To provide an inkjet recording apparatus and a method of investigating ejection failure determination performance whereby ejection failure nozzle determination performance is maintained at high performance, and productivity can be raised, even if paper, ink, or the like is changed.;SOLUTION: The inkjet recording apparatus is equipped with: a head having a plurality of nozzles for ejecting ink onto a recording medium; a means which conveys the recording medium; an investigation pattern generation means which generates an investigation pattern thinned out without ejecting the ink from a portion of the nozzles; a reading means which reads the investigation pattern output onto the recording medium; and a means which performs comparison and collation between data of the read investigation pattern and data of the investigation pattern generated by the investigation pattern generation means. The apparatus also has a function for finding a determination rate of ejection failure nozzles by outputting the investigation pattern onto the recording medium from the head, and performing the comparison and collation between the data of the read investigation pattern and the data of the generated investigation pattern.;COPYRIGHT: (C)2010,JPO&INPIT
