Abstract
A droplet ejection apparatus includes ejection failure detecting means for detecting an ejection failure, counting means for counting the number of ejection failures, and droplet receptor transporting means which carry out discharge and feed of the droplet receptor. The ejection failure detecting means detect the ejection failure with respect to a droplet ejection operation when the plurality of droplet ejection heads eject the droplets onto the droplet receptor. In the case where the number of ejection failures exceeds a predetermined reference value, the droplet ejection apparatus stops the droplet ejection operation and operates the droplet receptor transporting means to discharge the droplet receptor from and feed another droplet receptor to the droplet ejection apparatus to carry out a new and same droplet ejection operation with respect to the fed droplet receptor.
