Filament blob covering extruder

I discovered this on one of our work printers. I tried to preheat to melt. Didn’t work. Didn’t know if running another job would help or hurt? Maybe I need to take off the head and clean? I’ve searched for solutions but couldn’t find any for upmini2

Definitely disassemble the print head.

Thank you. That is what we did. It took quite a bit of cleaning but it is up and running.
