ABSTRACT:
A liquid-discharge-failure detecting apparatus detects a liquid discharge failure. A light-emitting element emits a beam onto a droplet of liquid discharged from a liquid-droplet-discharge surface with an optical axis of the beam making a right angle with a direction in which the droplet is discharged. A light-receiving element receives a scattered light generated by scattering of the beam by the droplet. A failure detecting unit detects the liquid discharge failure from data of the scattered light received by the light-receiving element. A distance changing unit changes a distance between the liquid-droplet-discharge surface and the optical axis of the beam based on, for example, a diameter of the droplet.
