FAQs & Troubleshooting

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

This error message occurs when the Brother iPrint&Scan application is unable to detect your Brother machine. Refer to the following steps to resolve this issue.
 

  1. Confirm the settings of your mobile device.
  2. Confirm your Brother machine is connected to the network.
  3. Confirm the settings and connection of wireless access point/router.
  4. Steps 1 through 3 have been confirmed but have not resolved the issue.

 

Step 1: Confirm the settings of your mobile device.

  • Is Airplane Mode setting OFF?
    When airplane mode is on, an airplane icon airplane icon appears in the status bar at the top of the screen and no wireless connection (e.g. Wi-Fi) signals are emitted from your mobile device. Therefore turn the airplane mode OFF.
     
  • Is Wi-Fi connection settings ON?
    The Brother iPrint&Scan application cannot be used on a cellular data network (4G/3G/E/LTE) connection. Your mobile device must be connected to your wireless network. Therefore turn the Wi-Fi ON.

 

Step 2: Confirm your Brother machine is connected to the network.

  • Turn off your Brother machine. Wait a few seconds, then turn it on again.

    Wait at least three minutes for the machine to join the network. Then start the Brother iPrint&Scan application.
     
  • Is your Brother machine configured for a network?

    If your machine is directly connected to a PC with a USB cable, you need to join your machine to a wired or wireless network. For the details about how to connect your Brother machine to a network, refer to the Quick Setup Guide. The latest Quick Setup Guide is available in the Manuals section of this website.
     
  • Is your Brother machine connected to the same network the mobile device is connected to?

    If your Brother machine is connected to a Wi-Fi network (SSID), confirm that the mobile device and your Brother machine are connected to the same Wi-Fi network (SSID).
    Refer to the following steps to confirm the connection to the same Wi-Fi network (SSID).
     
    Confirm the Brother machine network
    1. Print the Network Configuration Report.
      > Click here to see how to print the Network Configuration Report.
       

      The Network Configuration Report lists the current network configuration including the network print server settings (SSID, IP address and etc.).

       
    2. Locate the network name "<NAME (SSID)>" (SSID: Service Set ID) on the Network Configuration Report (List). Your Brother machine is connected to this SSID name.

     

    Confirm the mobile device network
    1. Tap the settings icon and confirm the Wi-Fi setting is ON.
    2. Tap Wi-Fi and confirm that the SSID is the same name your Brother machine is connected to. If not, choose the SSID the Brother machine is connected to.

 

Step 3: Confirm the settings and connection of the wireless access point/router.

  • 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>
     
    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 example1
    • (A)  Internet
    • (B)  Router
    • (C)  Wireless access point/router (router function set ON)

     

    <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.
     
    correct connection example2
    • (A)  Internet
    • (B)  Router
    • (C)  Wireless access point/router (router function set OFF)

     

  • 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. If these functions are running, temporarily turn OFF the settings.

    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.
     

Step 4: Steps 1 through 3 have been confirmed but have not resolved the issue.
