keep it simple!

I saw the sample, the only time I seen this issue is when the fuser unit was faulty. this is someting like oily stuff on the paper. never seen this before.
but thoes adjustment that i just mentioned will help to isolate the problems.I usally go to tech rep and do graduation first, then i run stibilization few imes, after that you need to run half tone test and change the adjustmet to 99 and check for each color and print the page, it prints solid color for c,k,y,m and the color is light because the half tone is change from 255 to 99. try and see if you have same issue.
I try to get some mor info for you. make sure your paper size also is set correct for the tickness, if it's glossy or regular, there are mny issues with selecting correct size.

you can get help from any expert and any certified filed engineer, every one welling to put out thier experties and some poeple may have more experience. I thinlk stirton.m getting it to complecated and it is not that complecated when you think of it. I personaly think the papaer could have
issue and you can alway stop the paper before exit to the fusing sextion. I think thoes setup and adjustment that i send you will determine the cituation a little. I always use these test before start repalceing parts and get down to changing transfer belt,fuser,print head and so on. I hop you get this going without any expensive part repalcement. let me know what happens.good luck

It's not that complicated. Adjustment of the cleaning bias is related to the transfer belt itself and is a VERY common issue with this series of machine. I immediately recognized that problem when I saw the image he provided. If you look at the image where the defect is, you will see that the ghosted image is obviously smeared and limited. Fuser ghosting does not do that. Fuser ghosting leaves an almost exact duplicate of the previous image, albeit a much lighter version.

Paper was 20lb. plain. The transfer voltage adjustment did the trick. Thanks for all the help. Will post if other problems surface.
