Get Help With the Toast Flex 3 Terminal

Toast Flex 3 Terminal Overview

Learn how to troubleshoot your Toast Flex 3 Terminal.

If your Flex 3 terminal does not power on when holding the orange button on the back, follow these steps:

Check for a green light on the adapter on the power supply cable.
If there is no green light, try another known working power outlet or connect your device to a working USB power adapter, such as a laptop charger.
If you do see a green light, open the base cover on the back of your display, or the base of your Flex 3 Terminal, to confirm cables are correctly connected, and the thumbscrew is completely tightened.
Each time you plug your cables back in, be sure to hold down the orange power button to turn the device back on. You will know the device is powering on when the front-facing LED blinks white.

Check the power indicator light on the printing hub. You’ll want to check that the Printer Power LED is lit and the terminal connection LED is lit and green.
If the printing hub terminal LED is amber, this indicates that the printer is currently receiving power, but your terminal is currently powered off. To turn it on, hold the orange button on the back of the terminal.
If there are no lights on the printing hub, check the printing hub power supply for a green light. If the device is not receiving power, try another known working outlet or cable.
If both the printer and power supply lights are green and the terminal still isn’t on, be sure the terminal is powered on by holding the orange power button. You will know the device is powering on when the LED starts blinking white.
Finally, try unplugging the printing hub USB cord from the terminal and plugging it back in. You will need to turn the device on again by holding the power button.

Hold down the power button for 7 seconds. You can release it when the LED light begins to blink white.
You will know the terminal has rebooted when the Toast logo appears.
If rebooting does not solve the issue, try performing a factory reset. Note: Before performing a factory reset, confirm there are no pending payments.
- From Toast Launcher: Press the circle button and navigate to Settings and Tools > Device Settings > System > Reset options > Erase all data (factory reset) > Erase All Data, then Erase All Data again.

If you are experiencing issues with your internet connection, try these troubleshooting steps:

Check your connection status
1. First, check the top-right icon in your terminal to ensure you have a connection.
2. Three icon types indicate a connection: Wi-Fi, Ethernet, and USB.

If none of the above icons are displayed
1. Remove the base cover to unplug and inspect your cables.
2. If any cable is damaged, you may need to replace it.
3. Be sure to reconnect your cables securely.
4. If your device is connected to a printer, see Get Help With the Toast Printing Hub.

If you are connected via Ethernet, try the following steps
1. Confirm your cables are properly connected, then reboot the device by holding the orange power button for 7 seconds.
2. Once the device reboots, check the connection by opening a web browser, visiting toasttab.com, and ensuring the page loads.
3. If this does not solve your issue, try checking your Ethernet settings.
4. On your device, navigate to Settings > Ethernet 0 USB or Ethernet 1 RJ 45.
5. Here, you’ll want to confirm that your IP is set to DHCP instead of Static, and make sure Ethernet is toggled on using the toggle bar at the top of the screen.
6. Finally, for devices using a wired connection, confirm that WLAN and Wi-Fi are not both enabled.
7. Recheck the connection by opening a web browser and visiting www.toasttab.com.

If you are experiencing issues with your Wi-Fi connection, see Get Help: Troubleshoot Network Equipment Error Messages.

If you are experiencing power supply issues with your Guest Display, try these quick troubleshooting tips:

Ensure the device is powered on
1. First, press the Orange Power button on the back of the Guest Display to ensure the device is turned on.
Check the brightness settings
1. 1. Confirm that the guest display brightness is not set to its lowest level. You can do this in the Terminal quick settings by swiping down from the top of the screen.

If you’re having trouble with a card reader or another accessory, like a scanner connected to your guest display, start by checking the connection.

Check the accessory connections
1. You’ll want to be sure all cables are securely connected to the ports on the Guest Display, Printer or Terminal.
Confirm the cables are securely connected
1. If connected to the Guest Display, confirm the green 90-degree USB cable is plugged correctly into the bottom of the Guest Display, and the Guest Display screen is showing an image.
2. If connected to the Printer Hub.
Reconnect the accessory
1. If connected to the Guest Display, try disconnecting and reconnecting the accessory from the Guest Display, and then disconnecting and reconnecting the Guest Display from the terminal.
Power cycle the terminal
1. If the accessory is not working after reconnecting, try power cycling the terminal by holding down the orange power button for 7 seconds.
2. You can release when the LED blinks white, and the Toast Logo appears.
