1 - 1 1 Introduction Two-dimensional Print Quality Assessment (2D PQA), a feature of HHP's image readers, identifies a successfully read symbol and also reports graded mea- surement parameters obtained from the symbol. 2D PQA is not "true" verification in the traditional sense of the word; however it can easily and inexpensively prov ...

1 - 2 • The hand-held imager has a view finder that projects a bright aiming beam that corresponds to the imager’s horiz ontal field of view. The aiming beam should be centered over the bar code and positioned horizontally over the code (no tilt, skew, or rotation). If th e symbol surface is shiny, the reader may have to be held several degree ...

Although often benign, Module Errors in the fixed regions of a symbol can signal a fault that, in some instances, will prevent pr oper decoding.
