seems a registration issue , you can try this :
I am experiencing similar color shifts. I have the most recent firmware 5.2.1 but it did not help nor did the new options. I have included a scanned in sample of the issue
I replaced the imaging processor board part 960K34661 after the first attempt at a firmware update failed. This color issue continued. I have reseated the imaging units, toner, and fuser with no change.
Thank you for any assistence you can give.
If its happening on multiple prints it could be the ibt belt or the mob sensor.
Have a tech run Regicon. It could also need a new config chip.
