Difficulty printing from your PC can occur for various reasons. The most common reason a networked Brother

machine may stop printing, is because the connection between the computer and the Brother machine is lost.

This can occur as a result of wrong settings or configuration of the printer driver.

There are several basic troubleshooting steps you can take to resolve this issue. For troubleshooting purposes,

disable any firewall programs that are running. Once you are able to print, enable your firewall again.

PART 1: VERIFY THE BROTHER MACHINE IS POWERED ON AND THERE ARE NO ERRORS

1. If the LCD screen is blank, then the Brother machine is not powered on. Verify that it is plugged into a

working outlet and any power switches are turned to the ON position.

2. Check the LCD screen for any error messages. An example would be -Paper Jam- or -Ink/Toner

Empty-. If the LCD screen shows an error, troubleshoot to clear the issue indicated.

PART 2: VERIFY THE CONNECTION TO THE WIRELESS ROUTER OR ACCESS POINT

1. Verify that there is no Ethernet cable connected between the Brother machine and the router or

access point.

2. Print the Network Configuration report:

a. Press MENU

b. Scroll to and press PRINT REPORTS.

c. Scroll to and press NETWORK CONFIG.

d. Press BLACK START. The report will print.

e. Locate the IP address of your Brother machine on this list. It will be displayed as

XXX.XXX.XXX.XXX. If the IP Address is 169.254.xxx.xxx, and you are not using an ad-hoc

connection, this indicates that there is no communication between the router and the Brother

machine. Continue to PART 7.

3. On the Network Configuration report, ensure that the Wireless Link Status states: LINK OK, then

continue to PART 3. If the status states LINK DOWN, FAILED TO ASSOCIATE, indicates a connection

error, or you cannot find the Wireless Link Status section, this indicates that the unit is not connected

to the wireless network. Go to PART 7 to setup the wireless connection.

PART 3: VERIFY COMMUNICATION BETWEEN THE BROTHER MACHINE AND COMPUTER

1. Obtain the computer’s IP Address:

a. On the computer, click START -> RUN

b. Erase anything in the open box and type: COMMAND

c. Click OK. A command prompt window will open.

d. Type: IPCONFIG

e. Press ENTER on your keyboard. You should receive information about your computer’s

network connection. Make a note of the IP Address. If you do not receive an IP address, this

indicates that there is a problem with your computer’s network connection. Try restarting the

computer, and completing PART 3 again. If you still do not receive an IP address contact your

router manufacturer or network administrator for support.

2. PING the Brother machine:

a. On the computer, click START -> RUN

b. Erase anything in the open box and type: COMMAND

c. Click OK. A command prompt window will open.

d. Type: PING xxx.xxx.xxx.xxx (Where xxx.xxx.xxx.xxx is the Brother machine’s IP Address

listed on the network configuration page printed in PART 2.)

Brother machine. When completed, you will receive the PING STATISTICS.
