More Information
Summary:The invention discloses a liquid ejection device and a liquid ejection method. The liquid ejection device includes: a line head having a plurality of liquid chambers storing liquid, heater elements generating bubbles by heating the liquid, and a nozzle ejecting a droplet from the liquid chamber using the bubbles; an ejection control portion that controls an ejection direction of the droplet to bea direction substantially orthogonal to the transportation direction of a recording medium; a line scanner that has resolution two or more times as high as resolution of the line head and detects a landing pattern made up of droplets landed on the recording medium; and control means for detecting a variance pattern of a luminance level of an output signal outputted from the line scanner to detecta deviation of a landing position of the droplet on the basis of the variance pattern and correcting the ejection direction to be a direction in which the deviation is eliminated.
