Droplet ejection apparatus and ejection failure recovery method

摘要

A droplet ejection apparatus of the invention includes: a plurality of droplet ejection heads (100); ejection failure detecting means (10) for detecting an ejection failure of droplets through nozzles; and recovery means (24) for performing recovery processing to eliminate a cause of the ejection failure of the droplets, wherein in a case where detection by the ejection failure detecting means (10) is performed for all of the nozzles and the presence of a failing nozzle in which an ejection failure is occurring is detected, recovery processing depending on the cause of the ejection failure is performed by the recovery means (24) at least for the failing nozzle, after which detection by the ejection failure detecting means (10) is performed again by forcing the failing nozzle alone to perform a droplet ejection operation. <IMAGE>
