Troubleshooting Procedures
This chapter contains troubleshooting procedures for diagnosing error
conditions on the printer system.
When a printer problem occurs, information may be displayed on the user’s
terminal if the /NOTIFY qualifier is included on the PRINT command line.
This information may indicate the cause of the failure.
Check the job trailer page from the print job, which shows some of the
messages that result from printing. Problems with the print files are indicated
on a file error page (see Section 6.6).
When a printing system problem occurs, examine the console output or
the OPERATOR.LOG file for operator communication manager (OPCOM)
messages. If your terminal is not running OPCOM, use REPLY/ENABLE to
enable PRINTER and CENTRAL messages. Restart the symbiont, and reprint
the job. Then you can read the relevant messages. This procedure requires
OPER privileges. Printer messages are listed in the DECprint Supervisor for
OpenVMS User’s Guide.
11.1 What to Do if a Serial Printer Is Not Printing
When you examine the OPCOM messages, look for a message from the printer
indicating NOTREADY. This message indicates that the printer is unable to
acknowledge any queries from the system. Check for the following:
• Faulty communication line or cable
• Incorrect port baud rate setting
• Incorrect switch settings or front panel settings
• Excessive line noise resulting in lost response from the printer
• No power to the printer
• Faulty connector or incorrect type of connector
• Incorrect bits/character, incorrect parity, or both
