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.

bar code verification products, including their portable Inspector
and Laser Inspector models, On-Line Inspector and AutoScan II
