Here I also attach pictures how hotend looks like before I start printing (clean it as much I can without removing it). And how it looks after 1,2 hour printing standart bearings which come together with standart SD from manufacturer.
Hi,
I always had the same behaviour you have with white Z-Abs, and my nozzle becomes dirty very quicly too, but I am not sure the two problems are linked. I've alreay printed Z-HIPS during hours with a dirty nozzle and never had a burnt point on the part.
If the object is small, please change the fan speed manually to 100%. It should improve the printing quality in that case.

The same , even bigger size than bearings from manufacturer SD.

I would not call this nozzles condition a drama. Mine looks similar (after printing 10-20 hours).
I clean it better than shown on your pic, I use a metallic brush when it's > 90% heated, no chemicals of course.

Mine after 1 hour printing.

Well I would not mind if there are no burn marks or blobs, but you tell that you get that.
I have no idea, actually the object you showed didn't look that bad, just try again using more fan for such small objects.
If it is a temp problem (printer too hot) you could try using another Profile to get lower temps, but if it is not like that your filament will stuck and you have to free your extruder again.
