Chapter 8: Troubleshooting
C Series printers require minimal user maintenance. When problems do occur, however,
it is important to isolate the root cause between hardware or programming issues.
Isolating Problems
Programming issues can often make problems appear hardware related. Use the
following steps to determine the source of the problem.
Run a Printer Self Test
A self test will help determine possible printer hardware issues since the test is performed
independently from all external software, cabling, and configurations.
To perform a printer self test please refer to Chapter 2.
NOTE: LEAVING THE PRINTER IN HEX DUMP MODE FOLLOWING A SELF TEST ALLOWS
THE USER TO SEE EVERY CHARACTER THAT REACHES THE PRINTER. USE OF HEX DUMP
MODE CAN HELP RESOLVE SOME PROGRAMMING PROBLEMS.
If the printer will not print a self test label, the problem is most likely hardware related
and the printer will not respond to incoming data.
Please contact technical support as referenced in Chapter 9 of this User’s Manual.
Print a Proven Label Format
Select a label format that has previously printed successfully on the system being
used.
If the proven format will not print, inspect the system for possible communication
problems. For example, ensure cables are connected properly and configuration settings
are correct.
If the proven format prints successfully, then most possible hardware issues have been
eliminated.
Print a New Label Format
If a known printable format is unavailable, then a new format may be created using an
available text editor. Creating and sending the simple format listed below should help
isolate the problem.
