Appendix A. Troubleshooting Problems
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 20 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; see “Example 1 — Printing the Printer Configuration Page” on
page 32 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 symptom and action table 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 at 1-800-358-6661 in the U.S.A. and
Canada.
5. 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).

Locating Printer Serial Number and Machine Type

If you need service on your printer, you will need to provide the serial number and
machine type:
1. Locate the printer serial number which is printed on a barcode label above the
toner cartridge. To find the serial number, open the top cover, and look for the
barcode label. Typically, the serial number is eight digits that start with three
characters. For example, MTC00002, as shown below:
