PAX Terminal Troubleshooting

Use the steps below to troubleshoot common issues with your PAX A80, A77, A800, or A920Pro terminal.

General Troubleshooting Steps

Restart the Device
- Hold the power button until the screen turns off
- Wait 5 seconds, then power it back on
Check WiFi Connection
- Slide down from the top of the screen to access the Settings menu
- Tap the WiFi icon
- Confirm that the device is connected to the correct network
Check for App Updates
- Ensure Corksy POS and payment apps are installed and visible
- If they appear missing or outdated, email [email protected]
Admin-Level Settings
- Some fixes require the PAX admin menu. If a step asks for the device admin password, try the following, in order:
  - corksy
  - pax9876@@
  - Today's date in MMDDYYYY format
- If none of those work, try yesterday's or tomorrow's date in the same format — the terminal may be set to a different timezone.
- Still stuck? Email [email protected] and we'll make the change with you.

Stripe terminals must be paired via Corksy POS and be connected to the same network.

Fully restart both devices
- Power off the device your terminal is connected to (iPad, desktop, or laptop) and turn it back on.
- Power off the terminal by holding down the power button, then turn it back on.
Ensure both are on the same network
- Confirm that both the terminal and your connected device are using the same Wi-Fi network.
Regenerate the pairing code
- On your terminal:
  - Swipe from left to right on the screen to open Settings.
  - Enter the Admin PIN (if you don’t have it, email [email protected]).
  - Select Generate pairing code.
Re-register the terminal in POS
- On your connected device, log in to your Corksy POS account (POS URL).
- Go to Settings > Register Stripe Terminal.
- Generate a new pairing code and enter the new Registration Code from the terminal.
- Click Connect Register.
Test the connection
- Return to the POS “Sell” screen and verify that products appear and the terminal is ready to process transactions.
