Vertical waves on MK4

Hello, after some work with the correct settings, I am actually very satisfied with the prints from my Prusa MK 4.
However, unfortunately it makes these unsightly vertical waves as shown in the photo.
Strangely enough, this doesn't happen across the entire surface, but only in the lower half of the printed part.
I've already checked everything mechanically (threaded rods, bearings, belts, etc.).
I'm printing with the original printer profile using Input Shaper.
Does anyone have any advice?
Perhaps the speed is too high, despite the original profile remaining unchanged.

Thanks!
