Hey Guys
I have a huge problem with a bizhub 1200. The problem is, that every 15'000-30'000 prints, the machine starts to spill toner. It is very bad and you can see it on the whole Page.
Normaly, i just replace the developer and clean out the whole Drum, cleaning and DV section and the problem is gone...for two days.

I have tried the following things:
-New modoified Developer assy
-New Drum Cleaning assy
-New Drum
-Latest Firmware
-Toner Spill countermeasure as descriped in the Service manual (helps, but the image gets blurry/cloudy, so no solution)
-The machine is on Level (measured with a round bubble)

I know there is a special Drum cleaning assy for customers who print less than 3% coverage, but my customer has a average coverage of 4.5%.

Machine information:
bizhub 1200
Year of construction: 2012
Tot. Counter: 1.7 Million

Anything would help.
Thank you in Advance
