I can't post photos here but I can tell you it's easy.
Use roll of adding machine paper so loose end starts at back of roll. Feed it into the slot on the back of the Casio. Then turn on calculator to print and push the first button on the left that looks like an up arrow. That will feed the paper into the calculator. When it shows up through the paper feed, put the roll on the paper arm and you're done.
Some people say you should cut the paper at an angle if you have any problems getting it to feed. I've never had a problem. This is the easiest and quickest paper loading calculator I've ever used.
