huge streaking problem on SF-7321 Thought maybe it was a paper problem, because it seemed to occur after i put new paper in it. Misfeeds a lot which sounds like paper is too thick, so I found an older package I had, still says 20 pound but feels a little thinner, not misfeeding so much, but still streaking like crazy.

I am working on a sharp AR-M550 with a paper tray error F3-12. Tray 1(paper tray desk trouble). I took the cover off of the front of tray 1 so I could watch the elevator. The one on the right side works fine, but the left one does not move up. I switched out the drive motor and gears from the right side to the left. It did not help. I then switched the small board that has the two sensors on it and that did not help. I took the gearbox apart and watched the worm gear and it would not even try to turn when I blocked the sensors. The right side did turn.Someone please help. I have spent 3 hours on this one. Also, I can't remember how to enter simulation mode.
