How to roll back the firmware on the HP Color LaserJet Pro MFP M479dw MFP, otherwise after the update there was a problem when printing any PDF scans, broken scans are printed, an example is attached. dU8xW48Shmg.jpg?size=1527x2160&quality=96&sign=b47fcad58feaf58b4d694b87f9b989ae&type=album
Even if you print a scan with a color signature, the whole image turns yellow ...
Such It became possible after the firmware update, but not exactly.

The hardest way is to go to the service and burn the flash with the firmware that works. This standard solution can be used by almost all mobile repair services.

As I understand it, the brains of the Color version do not differ so much, see if this MFP has a service mode, and then follow the video from yt

Have you tried checking the "print as image" checkbox in the PDF print properties? Often fixes PDF display problems
before firmware rollback - look for firmware on forums
