4. Ensure the printer power switch is on.
5. Ensure the AC outlet is working. 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.
6. Ensure the printer is on-line.
7. Examine the printer for a paper jam.
8. Run the printer internal self-test (if it has one) to make sure that the printer is functional. Refer to
the printer’s manual for instructions.
9. Ensure you have selected the correct port setting when you configured the printer. The printer
must be configured correctly for the Netserver and for the application. You may need to change
some switch settings on the printer.
10. Ensure you have not disabled the I/O ports. Run the
Setup Utility
(press
[F2]
during the boot
process) and verify the I/O port status.
11. Ensure the server’s printer port is working properly by running another peripheral from that port.
12. If the printer still does not work, it may have a resource conflict with another board or accessory.
Remove boards and accessories (except the hard disk drive) one at a time to isolate the
conflict. Check the printer for proper operation after you remove each board or accessory.
13. If an error message appears on the screen, refer to
Error Messages
and the printer’s manual
for help.
14. If the Netserver was working before you installed the accessory, remove the accessory and
restart the Netserver.
15. If the problem persists, replace the system board.

1. Review the
Troubleshooting Checklist
before you continue.
2. Ensure the keyboard is not locked.
3. Ensure the keyboard cable connections at the rear of the Netserver and at the back of the
keyboard are securely and correctly attached.
4. If a keyboard/monitor switchbox is used with this Netserver, plug the keyboard directly into the
keyboard port of the Netserver. Verify the problem.
5. If the problem persists, turn off the Netserver and back on by using the power button.
6. Try replacing the keyboard with a known good keyboard.
7. If the problem persists, check the keyboard cable for continuity, or try a known good cable.
8. If the problem persists, replace the system board.
9. Once a suspect part has been found, verify that it is the problem by reinstalling the part and
duplicating the error.
