We are struggling with a C250i and I'm hoping someone have any suggestion.
There is only yellow toner on about 6 cm in the front side fading from front to rear. Also you can no see the steps on the gradation prints like you can se on C,M and K.
The plack prints are a bit grainy but I don't know if this is related to the Y problem.
So far we have replaced Y drum, Y developing unit, transfer belt, high voltage board, PH unit, base board, and EXCB.
The total counter is 48000, OEM toner and the machine is clean inside.
