[bega]

Hello, i have KM c224e printer, last 1 week this printer start printing cyan pages not good, there was remain 10%. I thinked this problem is becouse of toner is become finishing. So i changed to the new one, but still that problem is have, also can not detect new toner, still remain 10%. I removed all toners and tried to printing, so its printing without any toners. Machine did not give me "input toner" message. Anyone had this problem?
If have a solution to it please say.
I tried already image stabilization, gradiation.. from service mode, but did not helped.
It looks like taking colors from developer. Any idea, please help!!!

Are you using OEM toner?
What is the consumable life and page counter?
Check in Level History 1, the percentage of toner in each UI.

First these toners don't have chips so changing them early will not register on the screen levels.

Also make sure the cyan developer didn't dump. If the cyan drum life is at "0" % there is a good chance developer dumped from overlife drum shorting out.
