Abstract
A droplet discharging apparatus includes: a droplet discharger including a pressure chamber, an actuator and a nozzle provided corresponding to the pressure chamber, and a discharge flow path coupled to the pressure chamber, the droplet discharger performing a recording process by discharging liquid in the pressure chamber from the nozzle in the form of droplets; and a return flow path coupled to the discharge flow path and forming a circulation path. The droplet discharging apparatus performs as a maintenance operation for the droplet discharger, a first discharge operation of causing the liquid in the pressure chamber to be discharged toward the return flow path via the discharge flow path when no droplets are discharged from the nozzle during the recording process.
