Those things amaze me. The way they manage to route just one sheet of paper through such an intricate and precise maze, I consider it next to miraculous that they don't jam on every second operation.
The bigger ones transport multiple sheets at once! The ones I work on can have up to 5 sheets running through the copier at once! It's really cool.
When you're printing 11x17 duplex (2 sided) it'll slide the paper under the machine whole it's rotating it. You can't see it, but I know it's happening.
That's basically how I got into the industry actually. Every problem is like a big puzzle I get to solve, and I get to help people, so it feels good at the end of the day
