Has any one seen cyan and magenta toner spots occuering on the output from the C6000? I have changed the developer with no luck and tech support had me change some setting but it is still doing it.

Hello,

Any updates on this issue. We have four machines doing it. It does appear to be an issue with the toner though.

Please advise.

It definetly has to do with the toner and KMBS is looking into the issue. I was able to clean it up by putting In a diffrent lot number cyan and magenta Toner cleaning out the sub hopper running toner refresh about 5 time then haveing the customer run there job to help finishe cleaning it out. The issue has come back with the magenta. The toner they were running now is a diffrent lot. They ran about two full bottles and most of another before it showed up. So it might not be something that affets a whole lot but just a few bottles. I would think the problem would show up quickly if it was the whole lot but it is hard to say.
