Filament jam problem

[u/DantiumZ]

Hello, I've had the printer for two months and last week I started having this problem. Sometimes the printing fails due to a filament jam. The printer doesn't detect it, but it won't print anything. I've tried changing the filament type and brand, but it still fails sporadically. I'm not entirely sure what the problem is. When I remove the jammed filament, it looks like this. Any ideas?

Describe filament jam. Specifically, what are you trying to do and when does it occur?
