Patent attributes
An ink jet recording apparatus includes a conveying mechanism configured to sequentially convey recording sheets, and a detector including a light source and a light-receiving element. The detector is configured to detect an edge position of each of the recording sheets. The apparatus also includes an ink jet recording head configured to eject ink droplets on each of the recording sheets, and a scanning carriage configured to move in a main scanning direction orthogonal to the conveying direction. The detector and the ink jet recording head are mounted to the scanning carriage. The apparatus also includes a determining unit for determining one or more characteristics of each of the recording sheets, and a storing unit configured to store the edge position of each of the recording sheets and the one or more characteristics of each of the recording sheets. Moreover, the apparatus includes a controller, and when the edge position of each of the recording sheets is within a predetermined edge position range, the controller is configured to control the ejection of ink droplets on a subsequent recording sheet, which sequentially is conveyed after a last of the recording sheets is conveyed, based on the edge position and the on e or more characteristics of each of the plurality of the recording sheets.
