It is an object of the invention to provide a droplet ejection apparatus
that can detect whether or not a missing dot (absence of a pixel)
actually occurs on a formed image, and can carry out appropriate recovery
processing according to a cause of the ejection failure without
conventional sequential recovery processing by identifying the cause
thereof in the case where a missing dot is detected. The droplet ejection
apparatus of the invention includes a plurality of droplet ejection
heads, ejection failure detecting means 10 for detecting an ejection
failure of the droplet through the nozzle, and recovery means 24 for
carrying out recovery processing to eliminate a cause of the ejection
failure of the droplet. The ejection failure detecting means 10 detects
the ejection failure with respect to a droplet ejection operation of each
droplet ejected through the nozzles when the plurality of droplet
ejection heads eject the droplets onto the droplet receptor. In the case
where the ejection failure is detected, the droplet ejection apparatus 1
interrupts the ejection of the droplets onto the droplet receptor and
make the recovery means 24 carry out the recovery processing in
accordance with the cause of the ejection failure.
