Abstract:
An inkjet recording apparatus includes a piezoelectric element, an extraction processing portion, and a drive control portion. The piezoelectric element is provided in correspondence with a nozzle, and upon input of a first drive signal, causes ink to be ejected from the nozzle. The extraction processing portion, when a print process is executed, extracts a non-ejection period during which a non-ejection state continues for more than a reference time period, from an execution period of the print process based on a plurality of pieces of image data printed in the print process, wherein ink is not ejected from the nozzle in the non-ejection state. The drive control portion inputs a second drive signal for causing the piezoelectric element to stir the ink in the nozzle, to the piezoelectric element during a partial period of the non-ejection period extracted by the extraction processing portion.

Claim (Index 5):
The inkjet recording apparatus according to  claim 4 , further comprising:\n a generation processing portion configured to generate print data in which the plurality of pieces of image data printed in the continuous print process are aligned in order of printing via one or more pieces of inter-paper data that correspond to intervals between the plurality of pieces of image data, wherein the extraction processing portion extracts, as the non-ejection period, a period during which a non-ejection pixel sequence is output, wherein the non-ejection pixel sequence is composed of non-ejection pixels that continue in the print data exceeding a reference number that corresponds to the reference time period, the non-ejection pixels corresponding to non-ejection of the ink from the nozzle, the drive control portion replaces each non-ejection pixel included in the non-ejection pixel sequence that corresponds to the period from the start timing set by the setting processing portion to the end of the non-ejection period, with a specific pixel that corresponds to the second drive signal, and the inkjet recording apparatus further comprises: a drive portion configured to drive the piezoelectric element based on the print data that has been subject to replacement performed by the drive control portion.
