Pressor foot not aligned with needle plate. Brother CS6000i.

I bought this off Facebook and they had aligned the needle into the holes next to the correct hole in the needle plate. Just so they could prove it worked real quick. I have spent days tearing this apart and learning about it. I found every other place to adjust things but I cannot figure this one out nor do I understand how this could even be misaligned in the first place. There are two screws that do affect this in the back but they don't actually do this kind of adjustment. I think there might have supposed to have been a wedge in the screw in the bottom in that picture that would alter the angle of this but somebody had messed with it and lost it. The machine works great besides this and I would like to get it running. Anybody have experience with this? And taking it to a shop is not a possibility. TIA.
