Chapter 8. Troubleshooting

General Troubleshooting Overview

The most common problems, which cause the print server to perform improperly, are covered in this

chapter. If a problem still exists after reading this chapter, please contact your dealer for technical

support.

1) LED Light Indicators

The print server is equipped with LED lights to assist in diagnosing problems that are the result of the

network and/or the print server hardware itself.

Power (Red)

When the print server unit is powered on, the Power LED will be turned on. This indicates that the print

server hardware is properly configured.

Wireless (Green)

Indicating the linkage and data transmission via wireless connectivity.

2) Power Related Problems

The print server requires an external AC power adapter in order for it to function. If you have a power

problem, check to see whether the power cord or its connectors are damaged. More importantly, check to

see that the AC power adapter included with the print server matches the AC voltage in your country or

area. Using an incorrect AC adapter will damage your print server.

3) Print Port Related Problems

Printing data failure may be caused by a loose connection of the print server to the USB port of the printer.

Check to see if any of the pins on the USB port connector are damaged. In addition, check the cable

connection. If the pins are damaged, contact your dealer for a replacement connector.

4) TCP/IP Troubleshooting

A. The print server's Node ID you specified in the "arp" command is not correct.

If this is the case, please ensure the Node ID field in the corresponding entry of the print server's IP

address in NT's ARP cache table is correct by typing the following command at NT's DOS prompt. "arp -a"

If the Node ID shown on the screen doesn't match the print server's Node ID, please follow the instructions

below to reset the entry.

1) At NT's DOS prompt, type "arp -d <print server's IP address>" to delete the current entry.

2) Type "arp -s <print server's IP> <print server's Node ID>" to specify a new ARP entry.

B. The print server's IP address is duplicated or is as same as another computer's IP address on

the network.

If this is the case, please consult your network administrator to obtain an unused IP address for your print

server.
