As far as I can see all the colors are affected in the same area crossfeed. I would think that this is an expansion or compression. the fuser speed may be too fast, jerking the paper from the registration roller. How heavy is the media?

On your sample, measure the distance from the flaw to the trail edge of the document. Then measure the distance from the registration roller to the transfer point at the primary transfer belt. I think you'll find that the dimension is the same. =^..^=

That is the fuser causing the issue, over time the pressure roller developes a flat spot causing that exact issue you have.
