server, it is divided into the following sections:
■General problems
■Network print software installation problems
■Printing problems
■Protocol-specific troubleshooting
General problems
CD-ROM is inserted, but does not start automatically
If your computer does not support Autorun, the menu will not start automatically after inserting the CD-ROM. 
In this case, execute setup.exe in the root directory of the CD-ROM.
How to reset the Brother print/scan server to factory default
You can reset the print/scan server back to its default factory settings (resetting all information such as the 
password and IP address information). See Restoring the network settings to factory default on page 3-8.
Network print software installation problems
The Brother print/scan server is not found during setup of the network print software 
installation or from the printer driver of the Brother machine in Windows®.
The Brother print/scan server is not found using the Simple Network Configuration 
capabilities of Mac OS
® X.
Make sure you have completed the IP address setting of the Brother print/scan server according to Chapter 
2 or Chapter 3 of this User’s Guide before installing the network print software or printer driver. Check the 
following:
1Make sure that the machine is powered on, is on-line and ready to print.

2Check to see if there is any LED activity. Brother print/scan 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/scan server is not connected to the network.
Link LED is green: The Link LED will be green if the print/scan server is connected to a Ethernet network.
3Print the Network Configuration 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/scan server. And make sure that no other nodes on the 
network have this IP address. For information on how to print the Network Configuration Page, see 
Printing the Network Configuration Page on page 3-7.
4Verify that the print/scan server is on your network as follows:
For Windows
®
Try pinging the print/scan server from the host operating system command prompt with the command:
ping ipaddress
Where ipaddress is the print/scan server IP address (note that in some instances it can take up to two 
minutes for the print/scan server to load its IP address after setting the IP address). 
For Macintosh
®
For Mac OS® 9.1 to 9.2
(1) From the Apple menu, open the Chooser.
(2) Click the Brother Laser (IP) icon, and make sure that your print/scan server name appears in the 
right frame. If it is visible, then the connection is good. Otherwise, go to Step 5.
For Mac OS
® X 10.2.4 or greater
(1) From the Go menu, select Applications.
(2) Open the Utilities folder.
(3) Double-click the Printer Setup Utility icon.
(4) Click Add.

(5) Make the following selection. Make sure that your print/scan server appears. If it is visible, then the 
connection is good. Otherwise, go to Step 5.
5If you have tried 1 to 4 above and it does not work, then reset the print/scan server back to the default 
factory settings and try from the initial setup again. For information how to reset to the default factory 
settings, see Restoring the network settings to factory default on page 3-8.
6Check if a personal firewall such as ICF (Internet Connecting Firewall) for Windows XP is running on 
your computer. If it is running, temporarily turn it off and try again.
Note
If none of the above steps are successful, there is almost certainly a hardware or network problem!
Printing problems
Print job is not printed
Make sure the status and configuration of the print/scan server. Check following:
1Make sure that the machine is powered on, is on-line and ready to print.
2Print the Network Configuration Page of the machine 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/scan server. And make sure that no 
other nodes on the network have this IP address.

Error during printing
If you try to print while other users are printing large amounts of data (e.g. many pages or color pages with 
high resolution), the printer is unable to accept your print job until the ongoing printing is finished. If the waiting 
time of your print job exceeds a certain limit, a time out situation occurs, which causes the error message. In 
such situations, execute the print job again after the other jobs are completed.
Protocol-specific troubleshooting
Windows® 98/98SE/Me and Windows NT®4.0 Peer-to-Peer print (LPR) 
troubleshooting
If you are having trouble printing on a Windows® 98/98SE/Me, Windows NT® 4.0 or later Peer-to-Peer 
network (LPR method), check the following:
1Make sure that the Brother LPR Port driver is correctly installed and configured according to the 
Windows® 98/98SE/Me or Windows NT® 4.0 Peer-to-Peer chapters.
2Try to turn the Byte Count on in the Configure port area of printer driver properties.
You may find that during the installation of BLP software, the screen that prompts you for a Port name is not 
displayed. This may happen on some Windows
® 98/98SE/Me and Windows NT® 4.0 computers. Press the 
ALT and TAB keys to make it appear.

Windows® 2000/XP IPP troubleshooting
Want to use a different Port number other than 631.
If you are using Port 631 for IPP printing, you may find that your firewall may not let the print data through. If 
this is the case, use a different port number (port 80), or configure your Firewall to allow Port 631 data 
through.
To send a print job using IPP to a printer using Port 80 (the standard HTTP port) enter the following when 
configuring your Windows
® 2000/XP system.
http://ip_address/ipp
Get More Info option in Windows® 2000 not working
If you are using a URL of:
http://ip_address:631 or http://ip_address:631/ipp, 
the Get More Info option in Windows
® 2000 will not function. If you wish to use the Get More Info option, 
use the following URL: 
http://ip_address
This will then force Windows
® 2000/XP to use Port 80 to communicate with the Brother print/scan server.

Web browser troubleshooting (TCP/IP)
1If you can not connect to the print/scan server using your web browser it may be worth checking the 
Proxy Settings of your browser. Look in the Exceptions setting and if necessary, type in the IP address 
of the print/scan server. This will stop your PC from trying to connect to your ISP or proxy server every 
time you wish to look at the printer server.
2Make sure that you are using the proper web browser, we recommend Netscape Navigator® version 7.1 
or later/ Microsoft Internet Explorer® version 6.0 or later.

Using services
A service is a resource that can be accessed by computers that wish to print to the Brother print/scan server. 
The Brother print/scan server provides the following predefined services (do a SHOW SERVICE command 
in the Brother print/scan server remote console to see a list of available services): Enter HELP at the 
command prompt for a list of supported commands. 
Where xxxxxx is the last six digits of the Ethernet address (for example, BRN_310107_P1).
Other ways to set the IP address (for advanced users and 
administrators)
For information on how to configure your network printer using the BRAdmin Professional utility or a web 
browser, see Setting the IP address and subnet mask on page 2-3.
Using DHCP to configure the IP address
The Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address 
allocation. If you have a DHCP server in your network, the print/scan server will automatically obtain its IP 
address from DHCP server and register its name with any RFC 1001 and 1002-compliant dynamic name 
services.
Note
If you do not want your print/scan server configured via DHCP, BOOTP or RARP, you must set the BOOT 
METHOD to static so that the print/scan server has a static IP address. This will prevent the print/scan server 
from trying to obtain an IP address from any of these systems. To change the BOOT METHOD, use the 
BRAdmin Professional utility.
Service (Example) Definition
BINARY_P1 TCP/IP binary, NetBIOS service
TEXT_P1 TCP/IP text service (adds carriage return after each line feed)
PCL_P1 PCL
® service (switches PJL-compatible printer to PCL® mode)
BRN_xxxxxx_P1 TCP/IP binary

Using BOOTP to configure the IP address
BOOTP is an alternative to rarp that has the advantage of allowing configuration of the subnet mask and 
gateway. In order to use BOOTP to configure the IP address make sure that BOOTP is installed and running 
on your host computer (it should appear in the /etc/services file on your host as a real service; type man 
bootpd or refer to your system documentation for information). BOOTP is usually started up via the 
/etc/inetd.conf file, so you may need to enable it by removing the “#” in front of the bootp entry in that 
file. For example, a typical bootp entry in the /etc/inetd.conf file would be:
#bootp dgram udp wait /usr/etc/bootpd bootpd -i
Depending on the system, this entry might be called “bootps” instead of “bootp”.
Note
In order to enable BOOTP, simply use an editor to delete the “#” (if there is no “#”, then BOOTP is already 
enabled). Then edit the BOOTP configuration file (usually /etc/bootptab) and enter the name, network type 
(1 for Ethernet), Ethernet address and the IP address, subnet mask and gateway of the print/scan server. 
Unfortunately, the exact format for doing this is not standardized, so you will need to refer to your system 
documentation to determine how to enter this information (many UNIX
® systems also have template 
examples in the bootptab file that you can use for reference). Some examples of typical /etc/bootptab entries 
include:
BRN_310107 1  00:80:77:31:01:07 192.168.1.2
and:
BRN_310107:ht=ethernet:ha=008077310107:\
ip=192.168.1.2:
Certain BOOTP host software implementations will not respond to BOOTP requests if you have not included 
a download filename in the configuration file; if this is the case, simply create a null file on the host and specify 
the name of this file and its path in the configuration file.
As with rarp, the print/scan server will load its IP address from the BOOTP server when the printer is powered 
on.
Using RARP to configure the IP address 
The Brother print/scan server’s IP address can be configured using the Reverse ARP (RARP) facility on your 
host computer. This is done by editing the /etc/ethers file (if this file does not exist, you can create it) with 
an entry similar to the following:
00:80:77:31:01:07   BRN_310107
Where the first entry is the Ethernet address of the print/scan server and the second entry is the name of the 
print/scan server (the name must be the same as the one you put in the /etc/hosts file).

If the rarp daemon is not already running, start it (depending on the system the command can be rarpd, 
rarpd -a, in.rarpd -a or something else; type man rarpd or refer to your system documentation for 
additional information). To verify that the rarp daemon is running on a Berkeley UNIX
®-based system, type 
the following command:
ps -ax | grep -v grep | grep rarpd
For AT&T UNIX®-based systems, type:
ps -ef | grep -v grep | grep rarpd
The Brother print/scan server will get the IP address from the rarp daemon when the printer is powered on.
Using APIPA to configure the IP address
The Brother print/scan server supports the Automatic Private IP Addressing (APIPA) protocol. With APIPA, 
DHCP clients automatically configure an IP address and subnet mask when a DHCP server is not available. 
The device chooses its own IP address in the range 169.254.1.0 through to 169.254.254.255. The subnet 
mask is automatically set to 255.255.0.0 and the gateway address is set to 0.0.0.0. 
By default, the APIPA protocol is enabled. If you want to disable the APIPA protocol, you can disable it using 
control panel of the machine. For more information, see APIPA on page 3-6. 
If the APIPA protocol is disabled, the default IP address of a Brother print/scan server is 192.0.0.192. 
However, you can easily change this IP address number to match with the IP address details of your network.
Using ARP to configure the IP address
If you are unable to use the BRAdmin application and your network does not use a DHCP server, you can 
also use the ARP command. The ARP command is available on Windows® systems that have TCP/IP 
installed as well as UNIX® systems. To use arp enter the following command at the command prompt:
arp -s ipaddress ethernetaddress
Where ethernetaddress is the Ethernet address (MAC address) of the print/scan server and ipaddress 
is the IP address of the print/scan server. For example:
Windows® systems
Windows® systems require the hash - character between each digit of the Ethernet address.
arp -s 192.168.1.2 00-80-77-31-01-07
