DETERMINATION OF MEDIA ADVANCEMENT BASED ON ONE PIXEL-WIDE MEDIA IMAGES

摘要

A method of an embodiment of the invention is disclosed in which a linear imaging array captures a first one pixel-wide image of media, and the media is effectively advanced relative to the linear imaging array. The linear imaging array captures a second one pixel-wide image of the media, and the first and the second one pixel-wide images are compared to determine relative advancement of the media.
