Patent ID: 8414100

Claim:
A liquid ejecting head inspection apparatus for detecting malfunction of a liquid ejecting head that discharges a liquid droplet from a nozzle opening as a result of driving operation of a driving element, the liquid ejecting head inspection apparatus comprising: a liquid droplet landing portion on or into which a liquid droplet discharged by the liquid ejecting head can land; an electric change detecting section that detects an electric change in the liquid droplet landing portion; a controlling section that performs control to supply a discharging drive signal for discharging a liquid droplet to the driving element, to generate a potential difference between the liquid droplet discharged by the liquid ejecting head and the liquid droplet landing portion, and to detect landing of the liquid droplet on the basis of a result of detection of the electric change detecting section when the electrically charged liquid droplet is ejected toward the liquid droplet landing portion in a state in which the potential difference is generated between the liquid droplet discharged by the liquid ejecting head and the liquid droplet landing portion; a non-landing section that ensures that no liquid droplet lands on or into the liquid droplet landing portion when the discharging drive signal is applied to the driving element; and a judging section that judges whether the liquid ejecting head inspection apparatus itself is functioning properly or not on the basis of the result of detection of the electric change detecting section.
