PROBLEM TO BE SOLVED: To enable an liquid droplet impact position to be adjusted (corrected) correctly by classifying the causes for an error in a liquid droplet impact position as due to a head mounting failure and as a deviation of the intrinsic discharge direction of a nozzle.;SOLUTION: The method for measuring an error of a liquid droplet impact position in a single mode comprises a liquid droplet impact process (S14 and S20) to discharge a liquid droplet from a liquid discharge head with a plurality of liquid droplet discharge apertures and make the liquid droplet adhere to the surface of a recording medium, a liquid droplet impact position error measuring process (S16 and S22) to measure an error (ΔX1 and ΔX2) of the liquid droplet impact position to an ideal liquid droplet impact position on the recording surface of the recording medium, from the liquid droplet impact results obtained by the liquid droplet impact process (S14 and S20), and an error factor classifying process (S24) to classify a first error component (δXH) attributed to a relative positional defect between the liquid discharge head and the recording medium and a second error component (δXD) attributed to the discharge direction failure of the liquid droplet discharge aperture. In addition, error information on at least either of the first or the second error component is acquired.;COPYRIGHT: (C)2007,JPO&INPIT
