Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
You can't really opening it with much chance of getting it back together successfully, there are quite a few very tiny parts (rollers, gears, springs, etc) that are not very friendly to work on. Your best bet is to take a piece of heavy card stock or even a thin metal ruler, and try to push that through the feed path to dislodge the paper jam.
