Abstract

The method comprises the steps of feeding media from a media roll, arranged about an axis, through an input driving device and an output driving device of the media advance mechanism, wherein the output driving device engages the media with lower friction than said input driving device; releasing said input driving device such that it does not engage the media; and causing the media to move in the media advance mechanism such that the media is pulled taut between the roll and the output driving device and later the media slips with respect to said output driving device, whereby the media is aligned at right angles to the roll axis by effect of the friction between the media and the output driving device.
