Congrats! Just keep at it, Fedora is stable.

It gets easier with every solved problem!

Mine doesn’t have a display (L3150), but you’re right about the deep cleaning. You doo need the utility for that.

I got away with 4 consecutive cleaning rounds…

edit: I’ve seen the button combination in your printer’s user manual.

You can start cleaning by a combination of Power + Stop buttons on the printer itself!

Monotheism finds a way.
