Abstract
A structure and method for employing the structure to reliably read indicia formed on a substrate such as a panel or wafer is disclosed. A gripping member pulls the substrate into at least partial compliance with a locating structure to facilitate the proper function of a code reader. Where the indicia are not read, the substrate is moved relative to the code reader, starting from a position that may be determined based on the material properties of the substrate.
