The error message “No Supported Devices Found” appears on the Brother iPrint&Scan screen (mobile device).

Fixing the “No Supported Devices Found” Error in Brother iPrint&Scan

If you’re encountering the “No Supported Devices Found” error message in the Brother iPrint&Scan app on your mobile device, it means the app cannot detect your Brother machine. Follow these troubleshooting steps to resolve the issue:

1. Ensure Your Brother Machine is Configured for a Network

If your machine is connected via USB, switch to a wired or wireless network connection.
Refer to the Quick Setup Guide for step-by-step instructions.

2. Check for Changes in Your Network Setup

Have you recently moved, changed your Wi-Fi network, or replaced your router?
Reconnect your Brother machine to the updated network using the Quick Setup Guide.

3. Verify Your Brother Machine is Powered On

Ensure the machine is not in Sleep Mode by pressing any button.
Check the power connection and switches.
If it won’t turn on, contact Brother Support.

4. Confirm Mobile Device Settings

Ensure Wi-Fi is turned ON (the app doesn’t work over mobile data).
For iOS 14 or later, enable local network access:
- Go to Settings > iPrint&Scan > Local Network.

5. Verify Your Brother Machine’s Network Connection

Restart your Brother machine and wait three minutes for it to reconnect.
Ensure both your mobile device and Brother machine are connected to the same Wi-Fi network (SSID):
- Print a Network Configuration Report from your Brother machine to confirm the SSID.
- Match the SSID with your mobile device under Wi-Fi Settings.

6. Check Wireless Access Point/Router Settings

Are there multiple wireless access point/router between your mobile device and Brother machine?
If your mobile device and Brother machine are connected to different wireless access points/routers, the mobile device may not be able to find the Brother machine depending on the configuration of the wireless access point/router.

Wrong connection example

(A) Internet
(B) Router
(C) Wireless access point/router (router function set ON)

If the wireless access point/router is connected to the router, refer to the following example to modify the connection.

Correct connection example1
Reconnect (wired or wireless) your Brother machine to the same access point/router the mobile device is connected to.

Correct connection example2

Turn OFF the access point/router’s router function (e.g. DHCP), in which you are connected to. For details to turn off the router function, refer to the access point/router’s User’s Guide.

Are the security functions of the wireless access point/router blocking the connection?

If the function to prevent the communication between devices that are connected, such as MAC address filtering and “Privacy Separator “/ “network isolation”, is set to run, the mobile device will be unable to find the Brother machine. To resolve the issue, temporarily disable these features if they are currently enabled.

If you don’t know the configuration of the security function, refer to the manufacturer of your wireless access point/router or ask your network administrator.

7. Further Troubleshooting

Connect a PC to the same network and verify printing from the PC to the Brother machine.
- For wired networks: Fix Wired Printing Issues.
- For wireless networks: Fix Wireless Printing Issues for Windows or Mac.
If the PC can print, uninstall and reinstall the Brother iPrint&Scan app from the Google Play Store or Apple App Store.

By following these steps, you can resolve most connectivity issues with Brother iPrint&Scan. For further assistance, consult your router’s documentation or contact Brother Support.
