INKJET RECORDING APPARATUS AND METHOD, AND ABNORMAL NOZZLE DETECTION METHOD

摘要

The inkjet recording apparatus includes: an abnormal nozzle detective waveform signal generating device which generates a drive signal having an abnormal nozzle detective waveform including a waveform that is different from a recording waveform and applied to pressure generating elements when performing ejection for abnormality detection to detect an abnormal nozzle among nozzles; an abnormal nozzle detective device which identifies the abnormal nozzle showing an ejection abnormality from results of the ejection for abnormality detection; a correction control device which corrects image data in such a manner that ejection is stopped from the identified abnormal nozzle and a desired image is recorded by the nozzles other than the abnormal nozzle; and a recording ejection control device which performs image recording by controlling ejection from the nozzles other than the abnormal nozzle in accordance with the image data that has been corrected by the correction control device.
