Thank you for trying, and sorry that didn't help.
Unfortunately, that really leaves only the possibility of a hardware fault at this point.
The one remaining thing you can try, just to be absolutely certain there is no remaining paper stuck, is to take a piece of heavy card stock and feed it into the printer from the front (where a printed page would come out) to dislodge any bits that may still be there. Then do the reset once more.
If still no change, we're back to a hardware fault. As a 2009 model printer, this type of fault wouldn't be surprising just from normal wear and tear, as they are designed for only a 3 year service life. Even if this jam issue had not happened, it was on the path to failure in the near future anyway. There is unfortunately no practical resolution here though.
While it can be fixed, it is not worthwhile to do so. You would have to, at a minimum, replace the printhead, which costs about $125; if the logic board is bad you’re looking at $200-250. For $80-100 you can replace the entire machine with a brand new model, with current technology and a fresh warranty, which makes more sense than buying the new part for an older printer.
