Gear Grinding Noise coming from MPT

Product Name: Xerox Phaser 4400
Operating System: Windows 10 x64

I had a paper jam from feeding card stock from the MPT (manual feed tray). I removed the paper from the access panel behind the printer (the inner roller area) and from the MPT, and ever since then have experienced a grinding gear noise from the MPT area, just to the left of the MPT. Any ideas what happened there? Is something out of place, a bad gear, or a timing issue? Will I have to disassemble it to figure it out or is there a known fix for this?

Could be a scrap of paper still stuck inside. Could be an actuator pulled out of place. Grinding only happens on bypass feed?

It happens when I turn it on and it does it's startup operation and then when I'm printing from other trays. I'll look inside to see if paper is stuck in there somewhere.

The only thing that comes to mind is drum cartridge or fuser(maintance kit)
