ABSTRACT:
In one preferred embodiment, a method of reading indicia disposed on a substrate moving relative to a reader, the indicia being parallel to and at a known fixed distance from a linear portion of the substrate, and the indicia normally moving relative to the reader along a fixed plane which passes through the reader, the method including; optically sensing the position of the linear portion relative to the reader; and in response to optically sensing the position of the linear portion, adjusting the reader such that the reader can read the indicia when the linear portion is skewed with respect to the reader such that the indicia no longer move along the plane. In a further embodiment, there is provided a method of preventing fluttering of a thin substrate, having upper and lower surfaces and having indicia thereon, as the substrate moves past indicia a reader with the lower surface moving over a base member spaced from the reader, the method including: directing a stream of gas against the upper surface of the substrate so as to force the lower surface of the substrate against the base member so as to maintain the substrate at a fixed distance from the reader.
