I'm going to be headed to a mpc 4500 in the morning that several techs have tried to fix. I thought that I would start here to see if any of you have come across this problem.
It is a mpc 4500 that is fading Black only (All other colors are fine) The fading starts at front frame and gradually fades to ablout 3/4's of the page. Eventually there is no image of black in the faded area.
The Black Developer unit, Developer and Drum have all been replace, along with the ITB unit and the cleaner unit. Also the Firmware has been updated.
Each time a tech is at the account and works on it they think that they resolve thed problem. only to have it return a few days later.
I am leaning towards the clutch for the Black developer, because it appears to me that the toner is not being fed to the front frame.
Am I on the right track or am I way off base? Any insight will be greatly appreciated.
