TL;DR

• got out and put back the printing head thingy
• tried to do no-print mode through the secret menu — it didn’t exit the menu and got back to the home page
• clicked mfg by error, it but me in the grid manufacturing thingy
• pressed once to turn it on
• turning it on it wanted to align the head, I pressed yes, it aligned the head
• printed a page
• after this the printer booted and worked.
• got a HP service manual: troubleshoting, had no details, but looks interesting for the future.
