Hi, I have KM C6000. Problem is in warm red tone. For example (100M, 100Y, 10K) when I have a duplex file where is on the first side red text and on the back full red tone, color is not same. Text is OK, but tone is pale printout over the entire surface. Controller is KM 601. It is like as turned option "toner save mode on full tone"
If any knows what the problem is?
