Abstract:
1. An image recording apparatus comprising: a conveying mechanism comprising a conveyance information generating section which generates conveyance information of a recording medium when the recording medium is mounted and conveyed in a conveying direction; at least one recording unit, which ejects monochromatic ink, and which comprises a recording head drive circuit and a plurality of recording heads each having a plurality of nozzles which are arranged along a perpendicular direction that is perpendicular to the conveying direction, the recording heads being disposed in one of: (i) a first disposition in which end portions of the recording heads that are adjacent to each other in the perpendicular direction are located on a straight line along the perpendicular direction, and (ii) a second disposition in which the end portions of the recording heads that are adjacent to each other in the perpendicular direction are spaced apart from each other by a predetermined distance in the conveying direction; a recording medium front end detecting section which detects a front end of the recording medium; a recording medium both-lateral ends detecting section which detects both lateral ends of the recording medium; and an integral control section which controls the conveying mechanism, and which controls the recording unit based on information from the conveyance information generating section, information from the recording medium front end detecting section, and information from the recording medium both-lateral ends detecting section, to record image data on the recording medium as an image; wherein the integral control section comprises: wherein the control section comprises: wherein the information on the ejection timing on the nozzle column of each of the recording heads comprises an adjustment value based on the design of the image recording apparatus.
