Abstract
Methods and systems for calibrating media indexing errors in a printing device are provided. In one embodiment, the method comprises feeding a calibration media through a printing device, sensing the position of the media as it moves through the printing device, sensing positions of a media indexing component as the media moves through the printing device, determining media indexing position errors based upon the sensed positions, and calculating a compensation factor to be applied based upon the errors. In some embodiments, parameters of a line and/or other function are determined from the error data and the parameters are utilized to calculate a compensation factor. Moreover, in some embodiments, it is determined what range the data fits within, and a predetermined compensation factor is determined based upon the range.
