This is a 97% perfect test print. What you see here is a feed calibration issue for the most part and a couple of slightly deflected nozzles. There are two passes of test print there and the dominant "thicker" part in the middle is the little overlap of the two passes.

Don't worry about it.

mrtn I am so glad that you are here and bring me back to life again and again .. Thank you so much, I just saw the difference to the last nozzle tests and I was immediately devastated.

I still have a picture of the dried attachments on my head:

The attachments are on the left edge.

So I can do nothing and my printhead stays healthy?

I don't know what you mean by dried attachments but if you are talking about the light drops on the left edge of the nozzle plate then these looks like cleaning fluid/ink mist. Should be wet, not dry.

Exactly these collections of liquid I mean on the printhead. I mean to recognize that I came with the sponge against it.. And I thought that the deflections come from it, is that possible? I understand that apart from the feed calibration I have / must do nothing right? Thanks again!

Your printhead is good.

Deflections can not come from the ink mist.

Check that your wiper is fresh and is installed correctly (blade pointing to the right).

Thank you Mrtn, have it fixed by offset. The nozzle test looks like it was before.

Can you help me with one more problem and watch this Video:
