Abstract (en)
[origin: EP2159058A1] A light-emitting element (30) emits a beam onto a droplet discharged from a nozzle (16). A light-receiving element (33) receives a scattered light generated by scattering of the beam by the droplet. A discharge-speed controller controls a speed of discharge of the droplet from the nozzle (16) to be set at the speed outside a normal discharge-speed range that is determined depending on a viscosity of a liquid. Finally, a failure detecting unit detects a liquid discharge failure from data of the scattered light received by the light-receiving element (33).
