Color issue Taskalfa 250Ci

[Froggy]

I've got a machine with a rare problem.
The color green changes in blue.

I installed a MK-865 en MK-865B a month ago and green is green en blue is blue. It seemed good.
But a week ago the green color changes slowly in blue.

I have done 464,412,410, registration en calibration. It seemed good.

But today green is blue again. Grrrrrrrrrrrrrr..

Who have an idea??

Check the magenta? Any C-codes logged? Could be defecting dev drive motor, drum motor, dev unit...etc. Always run U89 sample set on ledger to see the density of all of the colors. Try running U155 and look at the toner readings...the higher the number=the more undertoned the dev unit is...all units should be around the same value.
