I've been working on a CS650 with a floating registration issue primarily on 11x17...this machine has a new Image Processing board, PF-601 inclination sensor, has V.41 firmware, all ADU rollers cleaned; Both Side chart adjustments run on PF-601 trays 4 and 5 as well as Trays 1-3. 8 1/2 x 11 seems to run fine through the ADU, no centering/registration issues. I've run FD/CD mag, restart, centering, belt line speed, etc.

I'm hesitant to try physically adjusting the ADU; there are a couple of pinned adjustment plates on the ADU that will, I believe, change not only the position of the ADU but the pressure between rollers/pressure rollers.

Any thoughts???
