Abstract
An inkjet recording device is configured to cause a head control substrate to generate a first drive waveform signal and a second drive waveform signal. The first drive waveform signal is for applying, after 2 AL from finishing time of an ejection pulse Phaving a voltage Vand a pulse width AL, a cancel pulse Chaving a voltage V(<V) of the same polarity as the ejection pulse to a head. The second drive waveform signal is for applying, from finishing time of an ejection pulse Pfollowing an ejection pulse Peach having a voltage Vand a pulse width AL, a cancel pulse Chaving a voltage V(<V) of the same polarity as the ejection pulses to the head.
