Rispondi a: says out of paperOn mine (7520 Photosmart) the drive bar for the paper feed assembly has stripped the drive gear. The bar spins but the gear does not move. Lay a hand mirror on the paper tray about halfway in, and shine a flashlight onto the mirror. Angle it so you can see the drive bar (goes across the entire paper tray area) and the drive gear about two-two and 1/2 inches from the right side of the tray area. Go to tools on your touch screen, call for a status printout (first choice), and watch to see if the drive gear moves. Sometimes the drive gear slips sideways off the prepared area on the drive bar. Mind slipped off and also stripped the inside of the gear.
