How to fix issues on PAXA920pro

Device won’t turn on / won’t charge

  1. Make sure you are charging and turning on the device correctly.
  2. When turned off, the device charges with the adapter only up to 60%.
  3. Charging in the docking station is not possible with 0% battery.
  4. Turn on the device by holding the side button until the PAX logo appears.
  5. Try a different adapter/cable (USB → USB-C).
  6. Charge for a longer period – the device may need more time.
  7. Test a different power outlet.
Tip: If the problem is with the adapter, we can offer a new one for purchase.

Device is frozen

  1. Restart the device or remove the battery and turn it on again.
  2. Identify where the screen is stuck:
    • Blue screen = battery replacement required.
    • If PEDTempered error appears, it indicates damage → Warranty claim.

Connection issues

Weak print
