Hi!
I bought a damaged Ricoh C2550 it initially had the cyan toner in the black and the toner was mixed. I cleaned the hopper and changed all the developers and drum units. I also changed the transfer belt and the fusing belt. By error at the beginning I did a factory reset... Now that I have it working the printings are faded. I tried changing the bias and with that change i observed a little of improvement. Any suggestion? Is the factory reset the problem?
