Nice one!

I was printing along last night and came back to a dark printer! No power. I thought well, it has worn out. It has printed a lot in a year. It is about to get some upgrades so I figured i'd just pull it apart and figure it out then. Then I had the bright idea to check the fuse. What do you know. The fuse had actually broken. One of the end caps had come loose. New fuse and back in business.
Always start with the most obvious, simple stuff when trouble shooting.
