TROUBLESHOOTING

Network Printing Problems

Use the checklists in this section to identify the cause of network printing problems. If a problem persists, contact NEC Printer Technical Support at NecTech’s web site (www.nectech.com) 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 nothing will print.

Check the Network Settings Page

On power-up, the network printer produces 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 network printer.

Check other Network Users

Determine if other network 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.

Review Recent System Changes

Verify that any hardware changes (installations, modifications, removals), to the printer or network, were done correctly. If you added a new software application, make sure the program is compatible and installed correctly on the network.

Check Hardware Connections

•Be sure that your cable is a Category 5 twisted pair cable with RJ-45 connectors for 10/100Base-T ethernet.

•Check that the network connector is plugged into the RJ- 45 connector on the NIC.

•Try another cable to make sure you do not have a bad cable.

•If you are using a 10/100Base-T concentrator hub that does not support the link signal, use Manual Ethernet Port selection instead of the factory default, Automatic Ethernet Port selection.

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 self- test 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.
