It's alive!!! This is my roughly 20 year old Brother mono laser printer. I got it for £5 on Gumtree a few years ago. It worked for a bit but then started having paper feed issues.

I bought new roller rubbers for it a year or two ago but have been putting off taking it apart to fit them since. However today I did the job and it seems to have worked. 🎉

This thing is *so* user serviceable. There is a 250 page manual available online. Basically all the screws are identical and a sensible size.
