If your touchscreen feature is not working, or the screen is flickering, watch the video below or try these troubleshooting steps:
The great part of the Toast hardware system is that only one power supply and one Ethernet cable is needed to power the Toast Printer, Toast Flex, and Toast Tap. The power supply plugs into the Toast Printer or the Toast Hub, and a USB-C to USB-C cable connects from the Toast Printer or Toast Hub to the base of the Toast Flex terminal. No additional power cable is needed.

My Toast Flex keeps losing connection to the Toast Hub or Toast Printer
The USB-C to USB-C cable runs from the Toast Hub or Toast Printer to the base of the stand. This cable carries both power and internet (ethernet) to the Toast Flex. If the Toast Flex keeps losing connection, it's likely that the cable is loose. Reseat the cable by pulling it out and plugging it back in, and make sure the thumbscrew is tightened as well.
Note: After ensuring the USB-C cable is securely connected, the internet connection can take around two to three minutes to fully establish.
If your connection continues to cut in and out after securing the cables, you may need to replace one of the cables.
This indicates that a Toast terminal connected via Wi-Fi is not connected to the _Toast network. To resolve this, select Join Toast network to automatically connect your device to the _Toast network and resume normal printing function.
If your Flex terminal powers on and the Toast logo is visible, that means that the stand is broken. If your Flex terminal still won’t power on, your terminal itself needs to be replaced. Contact Toast Customer Care and reference code #504.

First, ensure EMV is turned on by following these steps:
If you've confirmed EMV is enabled but your Toast Tap™still won't read chip cards, make sure guests are inserting their credit cards the correct way. Dip cards should be inserted with the stripe facing the tablet and the chip facing away.

The cable for the Toast Flex for Guest wedge mount carries power, data, and video over a single cable. This means that it can't be coiled as tightly as other regular cables and must be routed straight out of the base of the stand.
