Welcome to Justanswer.com, my name is Dustin.I'm sorry to hear about the issue you are having, I will do my best to help you resolve it.
The feed rollers in your machine probably need to be replaced. As long as you arent getting any error messages, and all its doing is failing to pickup the paper, then this is the part you need.
Though, you could probably save some money by purchasing a broken unit on ebay and removing the rollers you need.
If you have further questions, let me know.
