I came in this morning and my printer showed Fatal Error 1A3F. It goes away when I restart, but shows back up after every print. Does anyone know what this error means and what I can do to fix it? Thanks.

Hi guys,

The motherboard overheats and the printer automatically stops with Fatal Error 1A3F .You need to check if any dust blocks the air flow and clean on both sides with a hoover (Image 1). The other possible reason is that the fan cooling the motherboard no longer works (Image 2). It's very easy to replace.

The fan model is 04020VA-24N-AL-00 from NMB Technologies:


For quick solution of your problem: you can open the top and use a usb fan. The goal is to cool down the aluminium radiator in front of the fan. I personally used a small metal plate placed on top of the radiator. I hope this helps :)
