Abstract
A liquid droplet ejecting apparatus, includes: an ejecting head which ejects liquid droplets; a light source which causes light to be radiated toward a flight space of the liquid droplets with a first output power or a second output power; a detecting element which detects received amount of the light radiated from the light source and passed through the liquid droplets flying in the flight space; and a controller. The controller causes the light to be radiated from the light source with the first or second output power at a timing of the ejecting head being driven to eject the liquid droplets; in a first detecting mode, executes a detection about an ejection failure of the nozzles based on the received amount of the light; and in a second detecting mode, executes a detection about a phenomenon causing the ejection failure based on the received amount of the light.
