Appendix A. Troubleshooting
This section provides simple methods for detecting and solving some of the problems
that most frequently occur in printing environments. If your printer does not print your
job, follow these steps:
1. Turn the printer off and leave it off for approximately ten seconds. Turn it back on.
This action resets the printer to its programmed configuration and may clear the
error.
2. Print a sample page to determine whether the problem is with the printer or with
the network or cabling leading to the printer. The printer configuration page can be
used as a sample page; see “Printing the Printer Configuration Page” on page 13
for instructions. If the problem is with the printer, it is likely that the printer will not
print the configuration page. If the problem is in the network or cabling leading to
the printer, the configuration page will still print.
3. Use the service checklist provided in this section to identify and detect problems.
4. Call your service representative. If you cannot solve a problem, call your point of
purchase or IBM customer technical support (1-800-358-6661 in the U.S.A. and
Canada).
Notes:
a. Have your printer serial number ready (it is located on the back of the printer).
Also, if you are asked for a machine type, specify 4312.
b. If you need IBM operating system support (for example, AIX, OS/2, OS/400,
and MVS), contact IBM software support (1-800-237-5511 in the U.S.A.,
1-800-465-2222 in Canada).
