I think I said earlier that a specialist from Xerox Mexico came on site took the machine apart, cleaned it couldnt find the problem and his suggestion is to buy a new machine. Welcome to my world! This is Mexico and they will hide from this problem and hope it will go away.
So as far as getting an experienced tech I would have to find one in the States or Canada.

OK
First load tray 2 with A3 80gr paper
While holding 0 (zero) press Start (button)
Enter 6789 Confirm
Press Print on touch screen
There is arrow up, press it until you get 11
Press M (magenta)
Press Start button and you'll get test print with only magenta color.
Exit diagnostic

Post that image so we can see it.

I did that test about a week ago and it doesnt show it as well as all four colours on the same sheet. When running the four different colour test. The lines are in the identical position for all four colours (really cannot see it that well on the yellow). I will try another test with four colours that maybe it will show better.
I have tried a new drum and it is the same.

uh
make 100% magenta square on A3 and print it.
Stop it before drum. (open front door) If you see strikes and banding on drum it can be only drum or laser. If not stop it on IBT.
If you see strikes and banding on IBT it's 1st BTR inside the IBT. If there is no problems with image on IBT, and you already said it's before fuser
it can be 2nd BTR.
