Abstract
A liquid droplet detecting device includes nozzles arranged in a paper width direction orthogonal to a paper conveying direction to discharge liquid droplets, a light emitting element provided on one side of the paper width direction to emit a light beam for liquid droplet detection, a light receiving element provided on the other side of the paper width direction to receive the light beam, a storage in which correspondence information on each of the nozzles and a scan position of the light beam when discharge of a liquid droplet from each of the nozzles is detected is stored, a controller to allow the light beam to scan according to the correspondence information, and a detector to determine presence or absence a liquid droplet discharged from each nozzle from an output of the light receiving element.
