I purchased an HP LaserJet CP2025, and it jams every time at the registration roller which I believe you can see when you open the rear panel. It seems like the roller doesn't move, I can hear two parts rubbing against each other before the printer tells me its jamming. The paper gets 2 or 3 folds at the front like it was being pushed from behind, but being stopped from the front.

I initially thought it was the pick up roller, because I had to remove the jam from tray 2 rather than from the rear. So I replaced the pick up roller, then I realized that it jams no matter which tray I feed from.
Another quirk about this is that the printer tries to print even if there is no paper in either tray. The black plastic piece that swivels near the pick up roller for tray 2 seems to be moving freely, so I don't know what it is.
So I have 2 questions:
1. For the problem of the printer attempting to print even without paper in either tray, what could be the cause of that?
2. If the jams are not related to a bad paper sensor, which part would I have to replace? A motor, solenoid, roller, etc?
I have the printer taken apart, so any other pictures you need, let me know. I am willing to be as invasive as needed with this printer.
Thanks!
