The printer displaying the message: UV LED is overheating! Check whether the heatsink is installed correctly.

Error name: UV LED heatsink overheating 

Error code: #10206

The error is displayed during the wizard. It mainly indicates a problem with the heatsink/cooling on the LED PCB. The ambient temperature is within range and the fan is spinning as it should, but the LED is still too hot. It means the heatsink is not installed properly and is unable to conduct heat out of the LED. 

How to fix it?

Access the UV LED panel using the replacement guide linked below and make sure it has 4 screws securing it to the heatsink, and that all of those are tight. If you find the components faulty, or the problem not resolved after reassembly, please contact support with pictures of your component.
