Method for inspecting liquid droplet ejection apparatus
A method for inspecting a liquid droplet ejection apparatus that ejects a liquid droplet from an ejection port includes (a) ejecting the liquid droplet toward an ejection target at an inspection drive frequency that is higher than an operation drive frequency set during a normal operation; (b) measuring a characteristic of the liquid droplet deposited on a surface of the ejection target; and (c) determining that the ejection port the characteristic of which is outside a predetermined range is defective.
