Patent ID: 7703871

Claim:
A liquid ejecting device comprising a head unit group in which a plurality of head units is arranged in a second direction perpendicular to a first direction in which a head unit having a nozzle group formed by aligning a plurality of nozzles that eject liquids and a landing target relatively move with each other, wherein the liquids are ejected from the nozzles to the landing target based on ejection serial data that is information representing ejection or non-ejection of each of the nozzles, 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 first 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 side 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 second 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 second direction, and wherein the corrected ejection serial data is divided into a plurality of block data corresponding to each of the head units and each of the block data acquired by division is transmitted to the corresponding head unit.
