Hi,
Iv also run into this problem on a c454. Spent weeks fitting parts, especially cyan dev units that drain the developer.
Recently had a KM Rep down for this and we went through the machine, checking the operation of the toner hopper section.
All seemed Ok, levels were fine. He then advised to change the HV board along with a new cyan dev unit. A week has passed and we have not heard from the customer (touch wood). Although I'm not entirely convinced it has solved the issue, I to would like to know if anyone else has experienced this problem, and how they resolved it. Spent so much money on parts for this.

No problem on my machines. The toner add does not work together it is the same as C360 only change is the reed switches was changed to Photo interuptors because of the developer bieng added to the toner it would get stuck to the magnet inside the sub hopper. Are you reseting the dev tanks? >dealer trick = buy only black Dev tanks and convert to color much cheaper<. The sensors cant see color only density!
Thanks Barber.
i had changed everything too on one specific machine. This was a C364e i also had a KM tech spec visit it had 4 dev units in all in a period of 6 weeks.
The copier was taken back to factory settings and re set up with the latest firmware.
This has beeen ok since but im not convinced.
This seems very unusual as it is only Cyan units i am have fail.
I had a C360 that did that on a cyan tank. The tank was empty when i replaced it. Striped out the laser to see where the machine dumped the dev but found nothing. I removed the HV board and cleaned all the conection points. The problem never came back. Check for corosion on the HV contacts mabe bad shipping caused corosion.
I am very interested in following this problem, but fortunately my company has had no issues. we must have 100 out there.
Thanks for the interest in this thread.
I am very confused with this issue.
There is no rhyme or reason why this is happening it just not make sense as it only seems to be the cyan unit failing.
It seems to be frailing at around 60k onwards.
I have now had over 70 fail on a MIF of over 300.
70 MFD's with the same fault & at differant locations?
There must be something that links them, a local power issue, your toner supplier?
Let us eat, drink, and be merry, because tomorrow we may die!
