摘要:
The liquid ejection device comprises: an ejection head including a plurality of nozzles which eject droplets of liquid onto an ejection receiving medium; a liquid flow speed determining device which determines a flow speed of the liquid in each of the nozzles, the liquid flow speed determining device being arranged in each of the nozzles; an ejection abnormality detecting device which detects an ejection abnormality in each of the nozzles according to the flow speed of the liquid determined by the liquid flow speed determining device; an ejection direction deflecting device which deflects a direction of ejection of a droplet of the liquid ejected from each of the nozzles, the ejection direction deflecting device being arranged in each of the nozzles; and an ejection compensation control device which performs control in such a manner that, when an abnormal one of the nozzles having an ejection abnormality is detected by the ejection abnormality detecting device, a compensatory ejection is performed by deflecting a direction of ejection of a droplet of the liquid ejected from one of the nozzles adjacent to the abnormal nozzle, by means of the ejection direction deflecting device.
