Liquid ejecting device and method of controlling liquid ejecting device

A liquid ejecting device comprising:

• a nozzle group formed by aligning a plurality of nozzles that eject a liquid;
• and
• a liquid ejecting head that ejects liquids from the plurality of nozzles based on ejection serial data that is information representing ejection or non-ejection of each nozzle of the nozzle group,
• wherein the liquid ejecting head ejects a liquid to a landing target while the liquid ejecting head and the landing target are relatively moved in a second direction that is perpendicular to a first direction in which the plurality of nozzles is aligned, and
• wherein the nozzle group includes a preliminary nozzle corresponding to an area outside a regulated landing area of the landing target,
• the liquid ejecting device further comprising:
• a meandering correction pattern forming unit that forms a meandering correction pattern along the second direction in a margin outside the regulated landing area of the landing target;
• a meandering correction pattern detecting unit that detects the meandering correction pattern formed in the landing target by the meandering correction pattern forming unit;
• and
• a data correction unit that corrects the ejection serial data in accordance with a deviation of the meandering correction pattern detected by the meandering pattern detecting unit,
• wherein the data correction unit adds dummy data, which represents non-ejection, corresponding to the amount of the deviation to the front of the ejection serial data in a case where the meandering correction pattern detected by the meandering correction pattern detecting unit is deviated from the original position to one side of the first direction and removes data, which is located on the front side of the ejection serial data, corresponding to the amount of the deviation in a case where the detected meandering correction pattern is deviated from the original position to the other side of the first direction.
