The problem is a small plastic gear that has slipped off a small steel shaft that runs the paper rollers that pulls the paper into the printer.

Easy to repair!

In order to see the gear, place a small mirror on the shelf that holds printing paper and view the top of the gearing mechanism. If the first gear on top closest to the front has slipped off the steel shaft, you have found the culprit! Simply put a small drop of epoxy of the groves that supports the gear in place and let dry....I just did and it corrected the issue.
