:confused:
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
