Feed a sheet of legal or similar through the bypass and watch it to see if it feeds, then stops momentarily, then continues. Your registration roller may be turning all the time causing the image to be shifted down. Also, can you scan service status pages so some of us can see printer settings?

hi , it feeds , stops and feeds again , not continuously

We are talking about system >1.488 Million pages!
Expected lifetime = 990.000 pages.
Inside from 6th Generation printers >45ppm you`ll find 1 registration switch and 1 image switch.
I think your image switch can be the problem.
Look at the partslist Fig 4/ Paper Feed section/ item #8/ 302LV24100 and check if it`s grinded from paper.
As you know, this switch is controlling leading edge laser start timing.

Come to think of it, I think I've seen a registration switch nearly cut in half at 1.8M prints.
