I can't figure this silly machine out. HP 4100N LaserJet... has a few years of heavy use on it.

I've checked for any tidbits of paper caught anywhere, sanded the rubber rollers to make sure they have some grip to em, but cannot find what's causing the jam.

It will start to load, make a little louder grinding noise, then I will see the paper caught on the bottom/tray roller, never having made it beyond the initial feed. It doesn't do this 100% of the time, it seems to come and go, but I'm fanning the paper and not re-feeding stuff so I'm doing everything right in that department. The paper looks like it's actually getting pinched between the tray plastic and the roller (sometimes it has roller size rips from this pinching). This seems odd to me because, by the looks of it, it would seem that it's rolling the paper in the opposite direction from where you would want the paper to go, but maybe that's a part of the design.
