That page is suppose to be faded at one end. It just occurred to me, its the auto color registration page. Black is the only one that is striping. So Drum, main charger, and black developer. I will give those a try.

Another question, why are the stripes in the black at a 45 degree angle? If it was the drum or something like that wouldn't they be perpendicular to the printing direction. I am not questioning your suggestion, just curious why its happening like that?

I Printed the auto calibration page and took a picture. Shared album - Joe Payton - Google Photos, the waves are actually how its printing. Not the camera.

is that actual waves in the paper or is it light dark areas.. if light /dark the developer unit is to blame

The easiest way to explain it is that the drum is arcing across it while the developer is turning, subsequently pulling developer from it. The rotation makes them appear diagonal. If it would just arc in one specific spot it would be a continuous line around the developer roller such as you see when there is an obstruction in the DV unit.
