I fix shit, its what I do. I can fix damn near anything you put in front of me.
Sometimes shit doesn't go the way it should. Sometimes some cheap stupid plastic piece broke that has never broke before and I don't know to look for it. Sometimes I just miss shit. Sometimes someone else has been in there and done things different than I do and I have to try to figure out what they did, then undo it, then redo it so it makes sense to me.
We just had the rollers go out on our warehouse printer. Thing had been cranking for 5+ years with no issues. Its just a laser printer, no copier, no duplex, nothing fancy. 3 different people worked on it before we gave up and bought a new one. Nothing was going together the way it should. That shit just happens sometimes.
