Identifying the Problem Use the checklists in this section to identify the cause of printing problems. If a problem persists, contact NEC Printer Technical Support at their web site (www.nec.com/nectechsupport) or phone 1-800-632-4650. Check the Printer Operation Verify that the printer is plugged in, turned on, and online-the green Online light on the Operator Panel should be lit (or blinking slowly if in energy saving mode), or nothing will print. Check the Network Settings Page On power-up, the NIC prints out a Network Settings page which has useful information for troubleshooting. Check the Network Settings page to see which protocols are enabled and active. Confirm that the network protocol you configured appears on the page. If not, it should be reconfigured correctly for the NIC. (For instructions on printing a Network Settings page, see page 6.) Check Printer Status on NIC Home Page Go to the NIC Home Page and click the Get Current Status button to view the printer status. (For instructions on how to browse to the NIC Home Page, see page 8.) Check other Network Users Determine if other users can print. If they cannot and they are all on the same network operating system, the problem is most likely in the network configuration. Check NIC Status Lights Check the NIC's status lights to ensure that there is no error condition. The two status lights, amber and green, are located on the interface panel on the back of the printer. The green light should be lit and steady. Light patterns that indicate serious hardware problems or software errors are shown below. If you see one of these patterns, you should contact NEC Printer Technical Support. Green light blinks rapidly: This occurs when the printer performs a self-test and detects bad SIMM. Green light blinks rapidly 4 times, pauses: This occurs when the printer performs a self-test and detects a problem in the Ethernet hardware. Amber light blinks short for 10 seconds, then goes out, and the green light blinks continuously: This occurs when the printer performs a flash memory selftest and the checksum fails. Green light blinks slowly: When this happens after power-on completes, it indicates an interface error. Green light blinks rapidly: When this happens while the printer awaits print jobs, it indicates that the NetWare connection has been lost. Green and amber lights blink alternately: This would occur when you turn on the printer after restoring factory defaults, and indicates an error. 43 TROUBLESHOOTING
