Some additional information...
The 1st piece of paper is about half way into the output bin when it jams. But at that point the 2nd piece of paper is just hitting the fusing assembly, and seems to start folding up here like it's not going through the fuser as fast as it is coming out of the registration assembly.
I marked the gear on the toner cartridge so I could perform a Drum Rotation Test. The toner cartridge drum does not spin. I tested this with 2 other toner cartridges that I pulled from working printers, same results.
