Has anybody ever seen such a printed image?

I saw something like this on a Toshiba Weisshorn 2H, after a power outage/surge.
I interpreted it to be laser self-focus problem. What I did is run the color calibration ... perhaps 20 times. Each time I did it it came back a little better. If I had done it ... oh ... 10 more times, it would have been perfect, but by then I was getting pretty irritated at how slowly it was coming back.

Doing it when copying & printing? All internal test pages do the same thing? Any codes?
I agree with BC it has something to do with the printhead. But since this has 4 separate laser units and all couldn't be bad I would look at a board as the problem.

Thank you for the answers.
There are no codes.
Color calibration makes no difference.
The same problem by copying and printing.
I swapped the mfp board but unfortunately without success.
Now, I will change the controller, because the ribbon cable of the laser units goes directly to the controller.
