Here's what you do. Take a look at the photo below.
Open the cover of the printer, where the ink cartridges are located. Behind the ink cartridges is the carriage, which is a box that moves side-to-side on a pair of rails. It's the thing that sprays the ink onto the paper.

You have to reach in with your hand and slide this thing to the center. Then, look to the very sides, left and right, for any bits of paper. If you look at the second picture, you can see my finger pointing to a small bit of paper that tore of and got jammed into the side. See the little crumpled bit of paper? It's preventing the carriage from sliding all the way to the right. You could have little bits on the right or left side. I had to reach in with needle-nose pliers to grab the paper bits out, but maybe your fingers are small enough.

Once the little bits of paper were out, I was back in business. Good luck!
