CHAPTER 3. TROUBLESHOOTING

Troubleshooting the 9460 printer is accomplished through messages displayed by the printer, built-in test
diagnostics, and manual troubleshooting. Certain errors are identified by error codes. Error codes and hardware
failure messages are listed in Appendix A.
Before troubleshooting, always fully charge the battery. Using a discharged battery pack can give false failure
indications.
The information in this chapter assists in identifying and/or confirming the failure of a replaceable module.
Troubleshooting is presented in an "ease of checking", "most likely to fail--least likely to fail" order. If the
replacement of the indicated modules does not repair the printer, contact Technical Support for additional
assistance.
