Konica 2 Million PM Kit, J-3901 1200 PRO Paper Jam Error

Replacing the fusing rollers, insulating sleeves, bearings and more on the fixing unit/ fuser of the Konica Minolta 1200 Pro Monochrome digital printing press. Also found a belt that is missing teeth. Hoping that is why 8.5 x 11 sheets don't want to feed.
