NAME:
TPM/ASP COMPANY (if no OUT REQUEST ID): ____________________PHONE: ________________
IMPORTANT! This checklist outlines proper electronics troubleshooting procedures and should be
performed by all Xerox employees, Authorized Service Providers (ASPs), Self Service Providers (SSPs),
and Third Party Maintenance (TPM) personnel on any job involving replacement of any of the three main
electronics components: Main Board, Power Supply, and Power Control Board. The completed checklist is
to be included with any failed circuit board returned to the factory. Also include print samples (if applicable
to the problem) and a Usage Profile Report printed after the problem has been resolved.
Before troubleshooting any printer hardware failure, be sure to disconnect the printer from the network or
host computer. The hardware ports on the main board are very reliable and almost never fail. If the printers
works when completely isolated, the problem is most likely related to the network or host computer
configuration or hardware.
Warning WARNING: When removing the power supply, always unplug the power cord
first.
Note NOTE: Always use static electricity precautions when handling the printer's
circuit boards.
Initial Checklist:
Turn the power off and back on to verify that the failure can be recreated. Then answer the questions below:
A. Does the failure occur during power-up (before the Xerox logo is displayed)?
B. Does the printer Reset or Reboot after initial power-up?
YES, use the Service Quick Reference Guide to troubleshoot the codes in the fault history (fault
history can be accessed in diagnostics if you are unable to get to that menu in normal mode). If
this does not isolate the failure refer to the Normal Operation Checklist
C. Is the printer displaying a fault code?
YES, Note the fault code: ______________________. Use the Service Quick Reference Guide to
troubleshoot the fault. If this does not isolate the failure refer to the Normal Operation Checklist.
D. Is the failure a communication problem with the network or host computer?
For all other Electronics problems (including intermittent failures), refer to the Normal Operation
Checklist .
Once the problem is resolved, answer the following (Xerox US personnel please document in
TechLink):
1. Which Checklist Item Number addressed the issue? _________________________________________
2. What was the corrective action? ________________________________________________________
3. Record the SERIAL NUMBER of any main electronics components replaced: ____________________
4. Note any additional comments: _________________________________________________________
