I intend to replace the internal harness of the group as well (photo 4), you never know! ... I got it from a 6002 here in the laboratory,

That is the harness that I have had problems with.

then Monday morning, before replacing the powerpack, I do a test first with that, hoping the connectors are the same, if not, I do a continuity test
I take a look also behind, from the back...who knows ever, that you find some other "surprise"

hello, update: yesterday I visit to the customer, the machine was actually back in code sc440-02, I tried to change the belt with the one I had brought but it didn't work, I could not find the black wire that breaks behind in black insulating tape , they were all blue, however none were damaged, then, by inspecting the machine better I found this (photo 1) there was a fall of waste toner from the graft of the gr.transfer into the drain, which literally buried the wiring connection in the macchine, this is the only anomaly I found ... obviously after I cleaned everything well (photo 2) , but the sc code continues undaunted.
the transfer current is there, because when printing the counter, the sheet jams in the middle of the hot roller, and the image is there!
it seems the IOB is not getting the correct feedback, and that's it from pin 6 & 7 on CN695(?) (photo 5) p.s. i checked on PtoP, and i discover that the order of wire pin connector of CN695 its same from 6002 at 6503, the feedback current and the feedback voltage pin 6 and 7 on 6002, are pin 6 and 7 on 6503, ...check it out too, it doesn't seem like I'm wrong (?) its different only the plastic connector that makes the transfer unit assy. incompatible from one to the other.
this morning the new power pack arrived, and on Monday I'm going to assemble it, I intend to replace the internal harness of the group as well (photo 4), you never know! ... I got it from a 6002 here in the laboratory, I hope it goes well, I will let you know as soon as possible.
it could have happened that the first power pack blew due to some strange short, caused by the dust that buried the connector, and then the second power pack only lasted 2 weeks, again for the same cause (?)

ciao luca, io intendevo dire il connettore frontale, quello che devi smontare quando togli la transfer unit.Io ho macchine che sono combinate peggio della tua nella foto, ma non ho mai avuto questo problema


Hello luca, i mean the front connector, it's part of the transfer unit.I have machines on the field that are much dirtier than yours, but never had problems with the wire on the pic

solved, after many days the new transfer belt arrived (D0CZ-3898) it seems that ricoh has changed supplier (I had to change some sp parameters) for this component, and there were problems with the availability.
however mounted, and the problem is gone.

Thank you for sharing the solution! Wich parameters had to be changed?

I changed these that you find in the attached bulletin, but in any case even without the bulletin, in the box of the new belt, there was a sheet with the same information to be entered via sp.
the belt is thinner than the "old type", and consequently the currents must be lowered slightly

D0CZ-3898 is it just the film or the assy?

I have so many 2nd hand metis in our storage circulation that I never needed to buy a new belt for our contract customers and we usually would just swap the entire assy + cleaning unit for non-contracts.

this is not Metis, but Martini series, it is only the rubber belt, it is the first time that it happens to me that it goes in code for the belt, I change them quite rarely
