摘要
A light-emitting element emits a beam onto a droplet discharged from a nozzle. A light-receiving element 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 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.
