@kolvin, If your happy with the purchase price, then go for it, I don’t know what price HP are charging for their OEM heads, which are probably made by a Chinese manufacturer anyway...

I believe there is a SLED Tool required for proper installation
what is wrong with printhead?
I've heard people TURNING their PRINTER UPSIDE DOWN to get air out??
I've not tried..

I'd go into hidden menu, Home, Back,Back,Back,Back
Look for printhead recovery
that fixed one on mine
