General Troubleshooting
Using Diagnostic Fault History
The general approach to using the Diagnostic Fault History utility is as follows:
1. Determine the diagnostic test necessary to reproduce a suspected
transient event.
2. Determine if the current logged events are important to understanding the
problem. If so, examine or record the events currently in the log, perform
whatever analysis is appropriate, and then clear the log.
3. Perform the selected test.
4. Re-examine the event list.
5. Identify an abnormal or suspicious event based on the test performed. For
example, a door open event while printing a test print when the door
remained closed.
6. As an example, assume the Interlock Switch is suspect. The process to
gain access to the switch will produce a number of events unrelated to
switch function. Therefore, you would:
7. Override the interlock function to provide power.
8. Access to the Interlock Switch actuator.
9. Clear the list with Fault History Master Clear .
10. Restart Diagnostic Fault History and manipulate the component or
connecting wires as required to reveal the switch’s condition.
