Diagnosing Problems
This section is designed to help the user recover from any
problems which may arise with normal printer operation.

Bar Code Verification

The single most important consideration when printing a bar code is
to ensure 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, which 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.
RJS designs and manufactures the world's most complete line of
bar code verification products, including their portable Inspector
and Laser Inspector models, On-Line Inspector and AutoScan II
series. For more information on RJS bar code verifiers, contact

Printing A Hex Dump

A hex code printout (or hex dump) is a translation of all host
interface data to its hexadecimal equivalent, listing all ASCII
character data received from the host computer with their
corresponding two-digit hexadecimal codes. Hex dumps are used
to troubleshoot printer data reception problems.
Printable characters print as the assigned symbol; nonprintable
characters are indicated by a period (.).
For instructions on how to enable and disable Hex Dump mode,
see page page -189. Figure 14 shows an example of a hex dump.
