Sorry for the late reply on this, I thought the developer unit was getting good coverage, but replaced the unit and it fixed all the issues even the magneta, suggests to mean the yellow developer unit was to stiff to turn properly and causing the magneta drive to slip

Pull the DV unit and roll it by hand. The developer should be nice and even. I also agree with bilyahn, clean the drum unit and make sure you use the setting powder. From your example, it could be the cleaner blade skipping on the drum surface.

Don't have your machine but on the smaller ones I have seen this happen with the drum units. If you look closely at the drum you will see the pattern like your 3rd image. For my problem I just cleaned everything and did a color calibration and it took care of the straitions. What have you done so far?

Good luck.

Sorry for the late reply maybe thats what is happening mojorolla the result is faint yellow marks from front to back of the page and you can see lines in them that seem to match the lines the run long ways on the mag roller

[mojorolla]

Do you mean blank spots where no developer will stick to the mag roll?

Has anyone had problems with the yellow developer unit shading one rotation of the mag roller on and off
