Continuous Paper Jam errors on Photosmart 7515 - No jams found
Product: Photosmart 7515
Spurious "Paper Jam" began intermittently, then became more frequent, and now is continuous. Haven't printed anything successfully now for over a week. I just walked through all the steps in the diagnostic video at the web page linked below. I was hopeful when I got to the "clean rollers" step since one of them had a fair amount of black ink on it, but no. Still continuous PJ errors.
