        I don't have any issues with it. Have done many times. I don't do it unless I'm in a pinch but sometimes you do what you have to do.

            After looking at it under magnification, it's most likely caused by one of these things. K drum, failing fusing sleeve, or a buildup on a really effed up pressure roller. I know you said all have been replaced, but that's still what I see. Problem appears to repeat every 3 inches or so. All of these things are really easy to check with your eyes, no swapping necessary.

                    This. Plus You're looking for something with diameter about 32mm. Print on A3 you should see the repeative patern(dots) 3-4 times. From your sample I guess the distance is about 100mm.

                            Looks very straightforward....fuser sleeve or drum.
