It print double sided from smc all fine. Did a couple tests.
I hereby declare, officially, that you all are free to scold me as much as you possibly could want.
Pic of the exit unit added.
It seems like this was it. Only that roller and that end was like this. There was some grooves in the axle, but not covering the full lenght of the bushing. I couldn't see any damage or wear inside the bushing after i cleaned that up.
I lubricated with a itty bitty amount of grease and put it together. I also lubricated all the other bushings in the exit unit with a tiny amount of grease and carefully wiped off the excess after assembly.
The grinding noice I've heard from the exit unit was the inverter motor going to full speed when the paper trailing edge was exiting the fusor. At this point the offending axle are still in contacting the paper and that axle would be driven by the inverter motor via the pull on the paper at a high feed rate, while the offending axle itself would only be driven at a lower feed rate by it's motor, and thus the requirement for the clutch. But when that axle had too much friction the inverter axle/roller was slipping a bit and the paper would only be feed at the slower speed of the binding axle/motor and thus the paper trailing edge would pass the inverter sensor too late causing a triggering of 064.
There was another model that had a similar problem with roller shafts in the exit section above the fusing unit. It would seize in the bushing and not turn thus rounding out the inside of the gear/pulley on the shaft. What you are seeing on the shaft is a type of lacquer left when the oil from the bushing gets cooked by the heat from the fuser. You might want to boil the bushing in silicon oil. This will open the pores of the bushing and allow the oil to be absorbed.
