Printing Errors or Lights & Stuck Print Jobs

I feel like I'll be banging my head against the wall having seen and felt exactly what an abundance of people looking for help have put up with, anyway.

HP Officejet Pro 8610, 4 years old (so yes out of warranty), casual use, well looked after and maintained, only on 3rd set of ink cartridges. Tried to print today and received;

"The printhead appears to be missing, not detected or incorrectly installed"

Well, it's not of those. It's there and hasn't been touched, moved or damaged in 4 years. From a quick research this is a very common issue that tends to drive those with it, insane due to lack of support.

Why am I livid? Firstly, the HP website(s) are the biggest load of crap I have ever come across. I have been round in circles, to dead pages, non-existing pages got absolutely no where in a vain attempt to get support, I guess the support mechanism of your website is in line with my printerhead, it doesn't exist or is broken.

I have had a registered account with HP for years, I registered all my products, yet it can't find anything of them when looking them up for support via serial, or HP assistant. Constant dead ends. There is no apparent way to contact support be it chat, email, phone, despite seeing all of these are supposedly available they are just impossible to find/get to. My serial number isn't recognised, half the time it says HP website is down or having issue. Nothing bloody works and I have literally wasted 3 hours trying to resolve the issue and then finding adequate support.

I have followed every single bit of available advice (on HP) and none of it has worked, specifically in regards to turning off/on, removing and resitting printerhead (multiple times).

The automated support features on the website are absolutely appalling so I pray to god I an get a helping hand here from someone because I'm ready to put my head through a window.
