Abstract:
1. A liquid ejecting apparatus comprising: a moving unit that moves by receiving a moving force; a plurality of nozzle row units, each of said nozzle row units having nozzle rows for ejecting liquid onto a medium, each of said nozzle row units being respectively adjustable in its position on said moving unit, said nozzle row units being successively arranged at different positions, respectively, along a line extending in a direction that is perpendicular to a line of action of said moving force, said line of action being a line that passes through points upon which said moving force acts and being in a direction of said moving force; and a controller that controls said plurality of nozzle row units, said controller being configured to make a nozzle row unit that is arranged closer to said line of action of said moving force than any other nozzle row unit eject liquid to form dots rows for adjusting said nozzle row unit that is arranged closer to said line of action of said moving force than any other nozzle row unit as a reference, said controller being further configured to make said nozzle row unit that is arranged closer to said line of action of said moving force than any other nozzle row unit and a nozzle row unit that is arranged farther from said line of action than said nozzle row unit that is adjusted as said reference eject liquid to form dot rows for adjusting said nozzle row unit that is arranged farther from said line of action than said nozzle row unit that is adjusted as said reference with respect to said nozzle row unit which is adjusted as said reference.
