CHAPTER 13 TROUBLESHOOTING
3.If you cannot make any of the connections in step 2, check the following:
a.Make sure the printer is powered on and
b.Verify that the cabling, network connection, and print out a configuration page in the Network STATISTICS information to see if bytes are being transmitted and received.
c.Check to see if there is LED activity.
•No Light:
If the LED (Link Activity) is off, then the Print / Fax server is not connected to the network.
•Orange: Fast Ethernet
The LED will be Orange if the Print / Fax server is connected to a 100BaseTX Fast Ethernet network.
•Green: 10BaseT Ethernet
The LED will be Green if the Print / Fax server is connected to a 10BaseT Ethernet network.
The LED will blink if the Print / Fax server is receiving or transmitting data.
When the Print / Fax server is receiving packets continuously, the LED might look ‘off’.
If you are using a repeater or hub, make sure that SQE (heartbeat) is turned off at the hub (if applicable). Also, if you have a hub or
4.If you have a bridge or router located between the Print / Fax server and host computer, make sure that the device is set up to allow the Print / Fax server to send and receive data from the host. For example, a bridge can be set up to only allow certain types of Ethernet addresses to pass through (a process known as filtering); therefore, such a bridge must be configured to allow Brother Print / Fax server addresses. Likewise, a router can be set up to pass only certain protocols, so be sure that the desired protocol can be passed through to the Print / Fax server.
