[CQ] CS500ci Back Ground on image?

[Joe Foe from Buffalo]

Only with black and white and the more that is run I get back grey ground on image. All looks good when run same image/original on color makes not difference via network or on exposure glass. Tried playing with U131 (K) service mode from manual 116 to 120 and only makes it lighter. Do I have a defective/bad (K) black unit? Unit/ (K) is original and has 722k B/W and 808K color.

Set 131 to 80 and swapped Yellow drum with black ran copies... it made it better but not perfect. One side is darker then the other also if that helps anyone help me.

If your developer and drums have not been replaced and are the original then you need to do a mianteance on it.

Ok the machine you are working on has a maintenance cycle of 300,000 prints on drums and developers so if you're telling me that all your drums and developers including the color ones have more than 300,000 prints on them then you should replace with both maintenance kits a and b.
