A copy of your Brother machine with the same name may have been created if you:
- Changed the USB port on the computer connected to the Brother machine.
- Installed the same printer driver multiple times.
When printing, always select a working printer driver. We also recommend deleting unnecessary printer icons.

- Turn the Brother machine on. If any other machines are connected, only turn the Brother machine on that you want to use.
- Click Start > Settings > Bluetooth & devices > Printers & scanners.
- Select your Brother machine.

Make sure the Brother machine's status.
If the status is idle, it means the printer driver is working correctly. Select this printer driver when printing.
