For details, refer to the User's Guide or Network User's Guide.
Step 5: Check the Firewall settings
Check for a Firewall setting on your computer.
If a Firewall on your computer is active, it may be rejecting the necessary network connection needed for the network scanning software to operate properly. Disable the Firewall on your computer and try the network scanning again.
Temporarily change your firewall/security settings to allow network connection.
Your computer's firewall/security software may be preventing the network connection from being established. If you receive firewall-related notifications, we recommend temporarily changing the security settings on your computer to establish the connection.
IMPORTANT
- Before disabling the firewall, make sure the changes you want to make are suitable for your network. Brother will not take any responsibility for any consequences of disabling the firewall.
- When finished, make sure to turn the firewall on again.
If the feature works properly after disabling the Firewall, this means the Firewall on your computer is rejecting the necessary network connection. In this case, Brother recommends you either disable the Firewall on your computer whenever you need to network scan using the scan key or leave the Firewall enabled and adjust the Firewall settings.
If the firewall blocks network communication, we recommend adding the following Internal/External ports in your firewall:
- UDP: 54925
- UDP: 137
- UDP: 161
Step 6: Uninstall and reinstall the Brother drivers
-
Uninstall and reinstall the Brother drivers.
If you are using a firewall other than Windows Firewall or Windows Firewall is off, you may receive a message warning you that the firewall could block network communication. See the instructions provided with your firewall software for information on how to add the following network ports:
- For network scanning, add UDP port 54925.
- If you still have trouble with your network connection, add UDP port 137 and 161.
-
Attempt to scan again to determine if the issue has been resolved. If you are still unable to scan:
- Verify that there are no security applications or firewalls running on the computer that could prevent network communication.
- Attempt to scan from another network-connected computer.
