Designing Your System

This chapter provides the information needed to set up a scanner
system correctly. Items include:

setup goals

symbol height and length

symbol quality

symbol orientation

tilt, pitch, and skew

determining read range

Each application must be evaluated carefully. Successful bar code
scanning begins with quality bar code symbols and the correct
number, type, and location of readers, decoders, and package
sensors. Refer to the following when designing your scanner system.

Adjust, if necessary, the symbol speed and/or the distance
between bar-coded packages to ensure that the bar code symbol is
being read.

Position the reader at a distance from the symbol that is within
the range specified. A read rate test should be made to verify the
range, and also to ensure optimum scanning and decoding.

If a package sensor is used, position it so it can sense the package
before the symbol reaches the scan area.
