bizhub 250 copy faded

[avio2]

I have a machine that makes copies of faded bands beginning with clear verical and then tends to make them completely faded, I have already changed developer and drum + clean corona charge and controlled the path toner perfect copies I made about 1000 and then resumed to do so
this machine have 100000 cp, any ideas ?

ps in A3 faded shorter in the sense

developer units are known to fail on these models. could be a bad spot on guide rollers. scan in a pic, let us have a sample.

Check that the "brass" connectors on the door are making proper contact with its opposite on the m/c, we've had m/c's where these have been deformed, causing "washed out" copies
