Abstract
The liquid droplet ejection apparatus comprises: a plurality of ejection ports which eject droplets to form dots on a recording medium to form an image on the recording medium; and a droplet ejection control device which, if a time interval during which one of the ejection ports does not eject any droplet exceeds a prescribed time period, and if an effect on the image, when a dot that is to be formed by a droplet ejected from the one of the ejection ports after the prescribed time period has elapsed is a defective dot, exceeds a tolerance limit, then causes the one of the ejection ports to perform an additional ejection of a droplet to form a corrected dot, in such a manner that the droplet is correctly ejected to form the dot of which the effect on the image would exceed the tolerance limit.
Claims5
A liquid droplet ejection apparatus, comprising:
- a plurality of ejection ports which eject droplets to form dots on a recording medium to form an image on the recording medium;
- and
- a droplet ejection control device which, if a time interval during which one of the ejection ports does not eject any droplet exceeds a prescribed time period, and if an effect on the image, when a dot that is to be formed by a droplet ejected from the one of the ejection ports after the prescribed time period has elapsed is a defective dot, exceeds a tolerance limit, then causes the one of the ejection ports to perform an additional ejection of a droplet to form a corrected dot, in such a manner that the droplet is correctly ejected to form the dot of which the effect on the image would exceed the tolerance limit.
