      If your machine's IP address is not within the range listed above, contact your network administrator or Internet Service Provider and request a correct one. You can then use the correct IP address to set the machine up again.

 

4. Remove any USB flash drives and memory cards from the Brother machine after use

  • This feature is available only for some models.
  • Illustrations shown below are from a representative product and may differ from your Brother machine.

If your Brother machine is connected to a computer via network, anybody can use the computer to access a USB flash drive or memory card inserted in the machine. If multiple users are using your Brother machine, we do not recommend leaving any USB flash drives or memory cards inserted. Remove the USB flash drive and memory card every time you have finished using them.
