Abstract:
1. A liquid ejecting apparatus comprising: a liquid ejecting head that ejects liquid from nozzle openings by the driving of an ejection driving portion; a driving signal generation portion that generates a driving pulse for the driving of the ejection driving portion; a liquid receiving portion that is disposed so as to oppose a nozzle forming face of the liquid ejecting head and receive ink ejected from the nozzle openings; and an ejection inspecting portion that detects an electrical variation occurring between a conductive portion of the liquid ejecting head and the liquid receiving portion when liquid is ejected toward the liquid receiving portion from the nozzle openings in a state where an electric voltage is applied between the conductive portion and the liquid receiving portion of the liquid ejecting head, thereby inspecting whether or not liquid has been ejected from the nozzle openings, wherein the driving signal generation portion generates a normal driving pulse which is used for processes other than an ejection inspection process by the ejection inspecting portion and an ejection inspection driving pulse which is different from the normal driving pulse and is used for the ejection inspection process by the ejection inspecting portion; wherein the ejection inspection driving pulse is configured such that the flying speed of the liquid ejected during the ejection inspection process is higher than the flying speed of the liquid ejected in response to the normal driving pulse.
