KMBH C6501 code C-2721 separation pole error

[Desert Rat]

I have been at this one unit since yesterday afternoon. I started out as lets do some maintenance after running
200K prints. 95% of the parts for copy quality were at 200% plus.
I rebuilt the transfer unit, replaced four drums and the black dv mix.
After hearing a thump noise from the back I got the code C2220. Transfer motor error, no encoder signal.
I see the encoder wheel is destroyed and the shaft wobbles. Once I got the transfer drive unit out, I saw
that a snap ring flange on the bearing came off and allowed the shaft to wobble.
Repaired that, now I am getting this C2721 code. I have already taken this apart 3 times for 5 other codes
but this one is not so easy.
Any advice welcome.

thanks

Fixed it.

I went back yesterday and removed the HV/2 board, held it up to the sun looking for cracks, none found.
Ohmed the sep charger from the front of the charger to the connector in the back. And just made sure
that all connectors were seated correctly. Big PIA job. But after the first 2 times it got easier.
Power it up, no smoke, ran a couple of adjustments and made copy. Then the customer started running his
jobs. No troubles.

Customer happy
Me happy & got paid
