Patent ID: 8888217

Claim:
An inkjet recording apparatus, comprising: an inkjet head in which a plurality of nozzles are arranged and a plurality of pressure generating elements corresponding to the nozzles are provided; a recording waveform signal generating device which generates a drive signal having a recording waveform and applied to each of the pressure generating elements when a desired image is recorded on a recording medium by the inkjet head; and an abnormal nozzle detection waveform signal generating device which generates a drive signal having an abnormal nozzle detection waveform and applied to each of the pressure generating elements when ejection for detecting abnormal nozzles in the inkjet head is performed, wherein the recording waveform is a waveform including, within one recording period, at least one ejection pulse for performing at least one ejection operation and a reverberation suppressing section for suppressing reverberating vibration of a meniscus after ejection, and the abnormal nozzle detection waveform includes ejection pulses and a reverberation suppressing section, and wherein pulse width of the ejection pulses and pulse interval of the abnormal nozzle detection waveform is the same as the pulse width and the pulse interval of the ejection pulses of the recording waveform, respectively, and a suppressing effect of the reverberation suppressing section of the abnormal detection waveform is reduced compared to the suppressing effect of the reverberation suppressing section of the recording waveform.
