Need some help for bad printing

Hello

I'm newbe. I mounted my MK3s's kit. My ten first printing was perfect but now, i have a problem as you can see...

This appears not at the same time (gcode ok)
I always use the same prusa filament (filament ok)
I didn't change parameters.
The first layer is ok.
I cleaned the nozzle.

What are your ideas about that?

Thank you for your response

Check your belts. They might be loose.

Thank you for your response.

Yes, the Y axis belt is to loose. I shall correct this in the evening. And I test it.

Finally, I think I found the reason :
My nozzle was not enough tightened. And sometimes, a little part of the paste fall in drop on the tip of the nozzle.
