I never let it stop me. I started working at a print shop, and the huge copier (xerox 1000i) kept jamming. I'm talking huge jams, this thing is about as long as 2 Mazda miatas.

The fuser belt tore on me at like 4 in the morning during an emergency print job, and the technician wouldn't be there until about noon, so I broke into his parts cabinet and figured out how to replace the belt. I had it up and running about an hour later. The fuser on that machine is about as big as a Brother desktop multifunctional copier.

He did come in, and scolded me for repairing it, but was fascinated I did it (it's a 2 week training in New York just to work on those).

I ended up bugging all the techs to hire me and eventually, they did! So now I work on photocopiers, and I absolutely love it.
