Security Software Problems

Problem
You did not select to allow access
when the Security Alert dialog box
appeared during either the standard
installation, BRAdmin Light
installation, or when printing
Incorrect port numbers are being
used for the Brother network features
Solution
See Security Software Problems on page 174.
 Confirm the IP address and the Subnet Mask.
Verify that both the IP addresses and Subnet Masks of your computer and
your Label Printer are correct and located on the same network.
For more information on how to verify the IP address and the Subnet Mask,
ask the network administrator.
Confirm your IP address, Subnet Mask and other network settings using the

Printer Setting Tool.
For more information, see Changing the Label Printer Settings on page 37.
 If the failed printing job is still in your computer's print queue, delete it.
For example, when using Windows
, [Devices and Printers] and select the Label Printer from [Printers
and Faxes]. Double-click the Label Printer's icon, and then select [Cancel
All Documents] in the [Printer] menu.
Uninstall the printer driver and the software, and then reinstall them.
Solution
If you did not select to allow access when the Security Alert dialog box
appeared, the firewall function of your security software may be blocking
access. Some security software may block access without displaying a
Security Alert dialog box. To allow access, refer to your security software
instructions or ask the manufacturer.
The following port numbers are used for Brother network features:
BRAdmin Light i Port number 161 / Protocol UDP

For more information on how to open the port, refer to your security software
instructions or ask the manufacturer.
