Hello, all!
I've replaced my print head but it turns out that new head was faulty (it wasn't actually brand new head but from other printer which I bought just for this printhead).
So, order of events was following:
Maybe VCC was shorted that why power supply wasn't able to start immediately after replacement?
Question is: what can cause to printer's head behave like that? I mean no error but also doesn't work properly. It probably should be something common for all colors/inks.
Head in question is QY6-0082. I've attached some pictures of both sides of head's pcb so maybe this help for someone who could deduce where to look for LV,HV and when to check if these voltages are coming. Should these be present all the time or only during actually printing something?
Thank you for any hints.

So, order of events was following:
- I had fully working printer except that BK was blurry
- I bought faulty printer (not powering on) to get head from it
- I put that head into printer and error B200 appeared
- I powered off the printer and put back old head
- Unfortunately printer doesn't reacted to power button at all
- After ~15 minutes I put power cord back and printer powered on
- Now i doesn't show any error but just prints empty pages
