Hello,
I'm having an issue on this KM C6000, under high humidity it starts dumping so much cyan toner I had to revert the toner density.
Already changed the corona, witch by the way was new, and same thing happens. Swapped the drum unit and still the issue.
Also noticed that the readings on humidity are not right, could this be the problem?
Machine has a PF-602 installed.

swap the cyan and magents DV units and see if issue stays with cyan or its another problem.
put tape over the holes when swapping and leave the toner door open while testing so it wont try to add toner.

I noticed that there is no white border on the sheet.


If your answer is YES, your problem is related to the cyan charging corona assembly. Corona, connection, fitting, HV board, something in that reasoning.


Moisture wouldn't do that.

Repleaced the Drum and the issue is gone for now.

Change the drum, corona, develop house, and see the result.
It's not too much time.

seen on a c6500 two weeks ago, also on the cyan, the corona wire is burnt, if you swap crowns the problem will go to another color, change the corona wire
