Diagnosing Problems
This section is designed to help you fix problems which may arise with normal
printer operation.
Bar Code Verification
The most important consideration when printing a bar code is to ensure that
the bar code will be scanned properly. Incorporating a bar code quality
procedure in the printing process is the best way to ensure that bar codes are
being printed correctly. A properly implemented verification procedure will
increase overall bar code quality, reduce waste from misprinted bar codes,
and achieve high first-time read rates. A high first-time read rate is an
increasingly important factor in newer, more efficient systems where manually
entered data is not acceptable as a backup function. Verification also
minimizes the costs of returned products due to poor reading or
unaccountable bar codes.
