Menuella Terminal Troubleshooting

Use this guide when Menuella Terminal cannot sign in, is not receiving orders, or shows an offline state.

If Terminal is offline

1. Confirm that Wi‑Fi or cellular data is available on the device.
2. Open Terminal's drawer and choose Help → Network diagnostics.
3. Check the network type, Wi‑Fi SSID, IP address, API latency, and WebSocket state.
4. Open Wi‑Fi settings from Terminal, reconnect, and return to the app.
5. Use Try again on the offline screen.

Orders are not available offline for security. Reconnect before continuing order service.

If sign-in does not complete

• Make sure the QR code or user code is current.
• Complete sign-in on the phone, tablet, or desktop browser opened from the Terminal screen.
• Approve the request that belongs to the Terminal in front of you.
• If the code expired, return to the Terminal welcome screen and start a new authorization request.
• Confirm that the signed-in account has access to the intended restaurant.

If Terminal does not receive new orders

• Confirm that the correct store is selected in the Terminal drawer.
• Open Help → Network diagnostics and check the WebSocket state and API latency.
• Confirm that orders are not paused in Order Settings.
• Restart Terminal after restoring the network connection.
• If the session is no longer valid, restart Terminal and follow the authentication screen again.

If printing fails

• Check the printer status shown by Terminal.
• Confirm paper and the printer cover on the Sunmi device.
• Use Settings → Printing & receipts → Test receipt.
• If customer receipts work but kitchen tickets do not, check the kitchen-print settings and whether kitchen printing is enabled for the store.

If the Terminal is being reassigned

Use Settings → Reset device / Unpair to remove the saved sign-in and store data. The next person can then authorize the Terminal with their own account using the QR code shown on first launch.
