3. If you cannot make any of the connections in step 2, check the following:
a.
Make sure the printer is powered on and on-line.
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 any LED activity
Orange LED: Power
This LED is on if the print server is turn on.
•
Yellow
LED : Link and activity
This LED is on if there is a valid connection to the network (either
10BASE-T or 100BASE-TX). Also this LED will blink synchronized to
the transmission or receive status. It is off if no network is detected.
•
Green
LED: Speed
100BASE-TX – LED is on.
10BASE-TX- LED is off
4. 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 multi-port repeater,
verify that the hub or repeater port is good by trying the print server on a
different port or on the other hub or multi-port repeater.
5. If you have a bridge or router located between the print server and host
computer, make sure that the device is set up to allow the print 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 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 server.
6. If the job exits the queue but does not print, make sure that you are not
trying to print a text job to a PostScript printer. If you have a printer that is
capable of automatic language switching, make sure that the printer is not
forced into PostScript mode.
