A droplet ejection apparatus is provided having a plurality of droplet
ejection heads each ejecting liquid within a cavity through a nozzle in
the form of droplets by driving an actuator with a driving circuit. The
apparatus includes: ejection failure detecting means for detecting an
ejection failure of the droplet ejection heads and a cause thereof; and
recovery means for performing a recovery process depending on the cause
of the ejection failure if the ejection failure detecting means detects
the ejection failure when the droplets are ejected through the nozzles.
Also, if a failing nozzle is detected, a recovery process is performed
depending on the cause of the ejection failure at least for the failing
nozzle. Thereafter, detection by the ejection failure detecting means is
repeated by forcing the failing nozzle to perform a droplet ejection
operation alone.
