Sounds like there is something in the paper track that's causing this to jam. Its not always easy to get small particles cleared just by removing the jammed paper.

This may not help everyone that I send it to, but it is worth a try.
I suggest you get a sheet of Card Stock (Heavy paper) and place it in the feed way. Then press
the print button applying a slight amount of pressure on the Card Stock so it will feed through the printer.
The reason for this is in some cases I have been able to clear the paper track of debris that was deposited there over time.
Worth a try, as I have fixed a number of printers this way, saving costly repairs.
Hope this helps. Bud
