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 provide test results that you may find useful for 2D
bar code symbol print quality process control. This User's Guide explains how
to activate HHP's 2D PQA analysis function, what is reported, how the data is
measured, what the readings mean, and what you might do to improve your
process.

User Operation

To utilize 2D PQA you need to have an IMAGETEAM™ 4600/4800/4X80 with
firmware revision 1.135.1.1 or higher or an IMAGETEAM 4410/4710 with firm-
ware revision 1.91.2.18 or higher..
To see displayed results using the 2D PQA feature, Microsoft
processor/editing program, or Quick*View is recommended. Refer to Chapter 2
for information regarding Quick*View.

Reading Techniques

Hand held movement, rotation, and location will affect the measured results. To
obtain proper repeatable reads that yield useful print quality information, you
should follow the techniques listed below.
• Lay the bar code symbol to be tested on a flat surface
• IT4600/4800/4X80: Hold the imager 7.0 in (17.8 cm) for SR models, 3.5 in
(8.9 cm) for the HD, and 4.5 in (11.4 cm) for the SF from the bar code sym-
bol. This distance is measured from the imager's front window to the read-
ing surface.
• IT4410/4710: Hold the imager 5.0 in (12.7 cm) for LR models, 2.0 in (5.1
cm) for the HD, and 7.0 in (17.8 cm) for the LX from the bar code symbol.
This distance is measured from the imager's front window to the reading
surface.
