Make sure you have completed the IP address setting of the Brother print server according to
Chapter 2 of this User’s Guide before installing the network print software or printer driver. Check
the following:
1. Make sure that the machine is powered on, is on-line and ready to print.
2. Check to see if there is any LED activity. Brother print servers have two LEDs on the back
panel of the machine. The upper side LED shows link status. The lower side LED shows
activity (Receive/Transmit) status.
No light: If both LEDs are off, then the print server is not connected to the network.
Link LED is green: The link LED indicates green if the print server is connected to a
Ethernet network.
3. Print the printer settings page and check if the settings such as IP address settings are correct
for your network. The problem may be the result of mismatched or duplicate IP address.
Verify that the IP address is correctly loaded into the print server. And make sure that no
other nodes on the network have this IP address.
4. Verify that the print server is on your network as follows:
For Windows

Try pinging the print server from the host operating system command prompt with the
command:
ping ipaddress
Where ipaddress is the print server IP address (note that in some instances it can take
up to two minutes for the print server to load its IP address after setting the IP address).
