Canon 250 MP problem

For a while, I had where my Canon MP250 would "print," but it wouldn't actually grab the paper. I looked around on several sites and YouTube, dealing with "Error Code 3 - Paperjam." My printer didn't have any paper jammed in it. I even tried "the card board trick," and I simply couldn't get the card board to go through, without bending. Then, I tried a random process to "reset it," as out lined here:

The semi-good news is that the printer prints, and grabs the paper. The problem is that it will "print" 1/4 - 1/2 of the page, before grabbing the paper (and a twice, it still won't grab the paper). I've tried both standard letter paper, and business card paper, with the same results.

Suggestions to fully raise my printer back from near dead?

If on reach back and unplug it. Let it sit for 1/2 hour or more. Plug back in and test.
Seen that work a couple times. Seen more printers replaced though.
