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.   Wait several minutes to make sure the job is not a complex one that takes       a long time to process and print. If a message appears in the message
      display area, see “Appendix C. Printer Messages” on page 205 for an
      explanation.
2.   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.
3.   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 24 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.
4.   See “Troubleshooting Checklist” to help identify and solve problems.
5.   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. The serial number is on a label       on the bottom of the frame inside the rear cover. It is also listed in the
      Machine Info Menu section of the printer configuration page (see
      “Printing the Printer Configuration Page” on page 24). If you are asked
      for a machine type, specify Infoprint 21.
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). Troubleshooting Checklist Printing Problems:
