Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Have you checked for any stuck pieces of torn paper inside the paper path?
Approximately how old is the printer?
Ok, if the paper path is clear then the only other possible cause would be a mechanical fault that is preventing the paper from feeding in correctly.
This type of fault would be unusual on a 3 month old printer.
Since the printer is still under warranty, your best course of action would be to contact the retailer or get in touch directly with Epson to arrange a repair:
