Looks like something is awry with the transfer belt.

Are those marks only black? Those marks looks digital.

Re-seat and reconnect the laser. Otherwise change the laser. I have not seen this on this model, I got that same pattern with B601 lasers before. Changing it was the only way to fix it.

Had one similar to that on a color Bizhub (don't remember the exact model, but it was a more recent one). I wasn't the one who gave assistance to it, but I believe it was solved with a new control board.

I seem to recall reading a bulletin about bad MFP board ram doing this too.
