Hello Copy addict
Just to make sure, use the transfer roller from a Bizhub 423 instead of the Bizhub 350?
If the collar seals are broken or have holes in them change them. The seals covering the ends of the mag roller.Originally Posted by wkwar
Change the transfer roller out to check if there is good change. Seen faulty HV boards do the same thing. So that would be next.
Or it could be something that you overlooked on the IU.
Is the drum covered in toner if you open the side door?
Does it feel gritty like there is developer in the mix?
Do you have experience on these machines?
Why? The only clear different is the removal of the black plastic like material covering the guide.
That got worn away after the first life cycle. Cheaper?
Whatever
Yes, we have found they cause less damage to the drum and they cost either the same or a little less
Someone told me to use the 250 roller assy on the 223 machines for the same reason.
Next time i have both in the same place i will take a vernier to them.
Whatever
Mag roller might be worn out if the ds rolls weren't replaced with the new ds roll kit A1UDR90100. We've been using those on the 350 series since they became available with good results, although the kit was made for the 423 series.
So, replace the drum and developer unit again (add new developer) but install the ds roll kit into the new developer unit and toss the black stock ds rolls.

hello srvctec
the ds roll kit replaces all the bearing and seals in the developer unit correct?
No it does not include the dev seals.
Whatever
sorry for so many questions, so the DS ROLL KIT A1UD371800 replaces the bearings inside the current developer roll correct?
on the transfer roll, should i get the
Bizhub 350 - PN 4040R72500 or
Bizhub 423 - PN A1UDR70500
We haven't bought a BH350 transfer roller, 4040R72500, in five years and there have been no ill effects. And there is less damage to the drum
