Abstract

A media alignment method includes printing a calibration pattern on a media in a print one by a printhead including forming a first corner identification marker at a first corner of a reference edge of the media, a second corner identification marker at a second corner of the reference edge, and a linear identification marker. The method also includes capturing the calibration pattern by an image capturing unit. The method also includes determining a printhead axis based on the linear identification marker, determining a default printhead origin based on the printhead axis and the linear identification marker, and determining a media origin based on the printhead axis, the first corner identification marker, and the second corner identification marker. The method also includes determining an offset compensation parameter by the determination module corresponding to a distance between the default printhead origin and the media origin.
