Abstract:
1. A direct marking printing system configured for substrate media registration without warping an image comprising: a print head with a plurality of print nozzles; a media transport unit to transport substrate media passed the print head; a deskewing system having at least one roller to deskew the substrate media; a reflexive system having one or more sensors to detect a lateral position of the substrate media on the media transport unit and at least one of the lead and trail edge of the substrate media while the substrate media is moving in the process direction under action by the media transport unit; and a controller operatively coupled to the print head and the reflexive system, the controller selecting a subset of print nozzles from which ink is to be ejected based on the lateral position of the substrate media on the media transport unit and determining when the ink is to be ejected from the subset of print nozzles in response to detection of the process direction position of at least one of the lead edge and trail edge of the substrate media.
