Couple questions about changing print head to JV150

[iat]

It's first time for me to change print head.

Do I need to type head id to machine or does it read it automatically?
Do I need to prefill new head with cleaning solution or can I just install it dry?

New head is original with board.

Plan is to change head and do Drop.pos correction, is there anything else I need to do?

It's 2 years old and already broken head, my previous JV33 run 8 years before I had any problems with it but motherboard fried.

Thanks in advance.

Nevermind, found manual.

After reading that I'm still unsure do I have to discharge dampers before removing those but I guess I'll follow every step on manual to be safe.
