MP6000 Developing ass'y seals

[apump]

I hear alot about these (front and rear seals) causing problems after awhile and I was wondering if this was the part # that is being replaced for this problem of spilling out toner. B140 3099 and B140 3100

No - On older models the mixer shafts had bearings with rubber seals. On the later models, they are just bushings B0653069.

These are developer front seals. I use to replace them for toner and developer spillage. P.N's must be correct, for the B064 series : Β110-3099 (F) and B110-3100 (R).
