Paper Feed Problem- HP 1510

This corresponds to the HP 1510 all in one model.

I was fixing a 'print job' deleting issue.

While iw as doing it the Printer took my paper in, i only had one.
I did something pretty stupid, as the paper came out i put it back in the feed side before it could say 'out of paper'. But i didn't need anymore paper.

Then something came down on it, i think it was the paper intake wheels, i thought it was gonna jam so i quickly pulled the paper back out, i think that might hav misplaced the wheels.

Now when i try to print, i hear the paper intake working but it doesn't seem to be in contact with the papers.

What can i do? :sigh:
