With all respect, I have read this 4-5 times and I cannot determine what your problem is.

The dot probably repeats every so often across the page. Use 11x17 (or A3) paper if you don't see it repeat. Measure the distance (precisely) between the repetitions and let us know what it is and we can tell you which component it is exactly.

If it doesn't repeat, it might be on the black IBT belt. (Technically, it is still repeating, but the belt is so long that it would never be on the same sheet of paper twice.)

But the ONLY time I have ever had a repeating defect on the belt was due to physical damage to the belt. So you'd be able to see the imperfection on the belt as you rotate it. I've never had the belt create a repeating defect and NOT be able to see the source of the defect on the belt. So you should hopefully be able to identify, or eliminate, the belt that way.

Make sure your pictures aren't too large (aim for 300 kb or so) or they will not upload.

If the 'big cyan dot' is more like a 'splash' of toner and not a clearly repeating defect, then toner is building up on your drum and spilling every now and then. But yeah, a picture would be nice.

Detonation makes an excellent point... If it is "spillage" out of the drum (which happens quite a lot, especially as a drum gets older) it would be random. It could be just a little, or it could be quite a lot.

One thing it WOULDN'T do is change color if you swapped it to a different color position. Because the backed up toner in the drum that is spilling out is cyan, it will STILL be that same backed up cyan toner spilling out even if you move it to magenta or yellow...

So keep that in mind if you're swapping the drums around to test.

And yeah, a picture if you can figure out how to attach it, will help immeasurably.

Good luck!
