Abstract:
1. A liquid ejecting apparatus, comprising: a liquid ejecting head capable ejecting liquid from a nozzle opening by means of a pressure fluctuation of the liquid in a pressure generation chamber, upon activation of the pressure generating unit; a drive signal generation unit that generates a drive signal including a drive pulse for driving the pressure generating unit; and a controller that controls ejection of the liquid by the liquid ejecting head, the controller forming a plurality of first inspection patterns on a medium in a head moving direction while moving the liquid ejecting head in a forward direction, forming a plurality of second inspection patterns on the medium in the head moving direction so as to correspond to the first inspection patterns formed on the medium while moving the liquid ejecting head in a backward direction, performing drive voltage reset processing for setting a voltage of a drive pulse at the time of patterns corresponding to a preferable combination of the first inspection patterns and the second inspection patterns formed in the inspection pattern steps, as a normally-used voltage used for normal forming, differentiating the voltage of the drive pulse used for forming the inspection patterns, for every combination of the first inspection patterns and the second inspection patterns in the aforementioned drive voltage reset processing, and forming the second inspection patterns corresponding to the first inspection patterns at timings when positions of the second inspection patterns in the head moving direction are theoretically aligned with the positions of the first inspection patterns.
