Have you tried a stop-test to see where it's appearing? It could be the transfer belt, if you've already changed the black drum. Or possibly even a dirty fuser?

I was just about to jump on that!

Guy you need a tech knowing this type of equipment and having the necessary experience and manuals.

What you are doing is almost as useful as Voodoo....

you mean the black line on side or the dots ? you copy or print the sample ?

Try Initialize+Stabilize in service mode. If it fails to improve the quality, I think it could be PH or PRCB. Black reproduction is poor below 90%.
All the best.

I am confused.....who actually has the problem? There are two posters on this thread asking for help but it sems to be the same fault!?:confused: Or have I flipped at last?
I agree that the grad adjust should be done!
