Good day. I have a C220 (under contract) but today ran into an issue. While running a short magazine job, the black type started to color shift to a dark blue, and then got faded.
So I ran a sheet of color bars, CMY we all fine. Black was not black, but kind of a faded dark blue. Is this a developer issue? THe black clutch was changed a year ago, but that resulted in blank pages, not faded.
In my old C450, this would have been a signal to change out the imaging unit.
As someone on here suggested, I tried an old black drum unit for the C220, and the result was the same. Toner is original , and brand new.
