i found the issue, its was the clutch just right before entering the ADU, you have to remove the high cap feeder, its called VERTICAL CONVEYANCE SECTION.
theres a clutch 56AA 8201 2 PAPER FEED DRIVING CLUTCH
says its MC13
i replaced that, all issue went away, its the hard to find clutches which gives issues if they are hard or do not stop moving then they need to be replaced.
good luck
