What happened?

The printer is displaying the message: Data is from unknown UV LED sensor!

Error name: UV data error

Error code: #10533

After calibration using the UV calibrator, the data was decoded successfully, but it was not possible to check its consistency. This is caused by using an unknown/unsupported calibrator.

How to fix it?

If you used the calibrator supplied by Prusa Research, please contact customer support.

If a third-party calibrator has been used you will need to purchase an Original Prusa UV calibrator from our e-shop.
