Re: bizhub 350 copy problem

@Hans: I have not yet swapped the HV but I'm now in the process of testing it. I'll be back for the feed back.

@pepper38_cnd: the drum is physically in good condition and no damage at all. All cleaning section were cleaned.

Re: bizhub 350 copy problem

I have the same problem. I changed the cleaning blade and I used the old drum because the new one was not the proper one. I said it doesnt matter to have a new blade with old drum for 2-3 days till the new drum arrives.
Before replacing the blade the copier was printing ok but with tiny dots from normal wear of drum.

Hi there!
Yes it sounds strange, but about 10 month ago my fellow technician had a similar problem and after some day's he got the solution: the customer had opend the OEM-Tonerbottle & put in some old toner he had in his desk!After changing developer & new toner the problem was gone. You can imaging his cursing about this stupid customer!

Yes the toner can be a problem but this copier is the copier that I use in my own copy shop.

Genuine bizhub 350 drums come as a unit.

why dont you try a GENUINE NEW drum unit and a GENUINE NEW developing unit with GENUINE developer and see what happens.

I NEVER have any problems with these machines at all, ever.

And of course a new copier.

Why not calling a service tehnician?


First of all this forum I GUESS is NOT for people replacing CRU items like Genuine fusing unit, Genuine Dev unit, Genuine drum ...
And I am Ricoh service engineer with few years of experience.

And I realized where the problem can be, the conductive grease on the drum pin. I remembered what I have done

Re: bizhub 350 copy problem

You just answered the question, if you put a good working developer assy in the machine and it is destroyed and no longer works in any machine then you have a toner problem ( it doesn't matter if you have verified that the now installed toner is OEM ) there is definitely the wrong toner in the toner hopper! That is the only thing that would move back to the previously working machine from the non working machine.

but if it is a toner problem a c2557 will arise.these machines are famous for c2557
