Printer/Datacomm Problems
Symptom:
• A printer does not print or datacomm devices are not working
If the printer does not work, or the datacomm devices are not working, do the following:
1. Review the Troubleshooting Checklist before you continue.
2. Verify the AC power cord is plugged into the power source and the printer.
3. Ensure the printer power switch is on and the AC outlet is working.
4. If the printer is plugged into a multiple-outlet box, make sure the switch on the outlet box is turned on,
and the circuit breaker (if equipped) is not tripped.
5. Ensure the printer is on-line and available for printing.
6. Verify correct cables have been used, the cables are connected properly, and the cable pins are not bent.
Refer to the peripheral's manual.
7. Check the cable for continuity, or try a known good cable.
8. Examine the printer for a paper jam.
9. Run the printer internal self-test (if it has one) to ensure the printer is functional.
Refer to the printer’s manual for instructions.
10. Ensure you have selected the correct port setting when you configured the printer.
The printer must be configured correctly for the Server and for the application. You may need to change
some switch settings on the printer.
11. Run the Setup Utility (press [F2] during the boot process) and verify the I/O port status, ensuring you
have not disabled the I/O port.
12. Ensure the Server’s printer port is working properly by running another peripheral from the same port.
13. If the printer still does not work, it may have a resource conflict with another board or accessory.
a. Remove boards and accessories (except the boot disk drive) one at a time to isolate the conflict.
b. Check the printer for proper operation after you remove each board or accessory.
14. If an error message appears on the screen, refer to Chapter 5, “Error Messages” and the printer’s manual
for help.
15. If the Server and printer were working before you installed an accessory, remove the accessory and
restart the Server.
16. If the problem persists, replace the system board.
