Printhead appears to be missing not detected or incorrectly installed
I’ve read through most of the other threads on the internet about this problem, but I’m still creating this one both for documentation purposes, and in case someone has a solution that I’ve not thought of! Text in bold are considered important for the troubleshooting.
I bought the HP OfficeJet Pro 8620 printer in 2015 and up until december 2019 it has worked perfectly. One day out of the blue, I recieved this error message: “The printhead appears to be missing, not detected, or incorrectly installed. Error code 0xc19a0023" . I reseated the printhead one time and the printer worked until next day, when the same error appeared. I followed HP’s troubleshooting steps 1. reset printer 2. reseat printhead 3 times 3. updating firmware, but no luck. I’ve disassembled the printhead and cleaned the contacts on PC board. I ordered this cleaning solution and cleaned the printhead, both soaking in the solution for some time and pushing the solution through. No luck. I then went on to buy this new print head from eBay, but the new one instantly gave the same error message.
Then I continued to troubleshoot some more. Since the new printhead failed I thought maybe the problem is in the printhead carriage inside the printer. I disassembled it and cleaned the contacts on the PC board. (This one is also possible to buy on aliexpress , but I’ve not done it). Everything looks ok. All the pins are undamaged. I’ve reset the CMOS battery on the main board, disconnected all cables and checked the cables specificly for the printhead carriage. I don’t have the equipment or knowledge to test if the cables actually work, but everything looks ok. Still getting the error message.
One last thing that I came by today on this page is that it might be the unoriginal ink that I installed for the first time last time I replaced my cartridges (about 3 months ago, I switched the last color from original HP to unoriginal). Could it really be the problem? Is it still worth a try to buy new original HP cartridges and will it even fix the problem? Or is the damage done already and not reversable? I’m a bit hesitant to invest more on this printer since I already blew up 72 EUR for the printhead…. Returning the printhead to China from where I live costs almost 40 EUR so it’s not worth the refund.
EDIT: I found an official statement from HP about a new firmware update removing Dynamic Security Feature which makes the printer fail when unoriginal ink is installed. However they explicitly say it’s only connected to a cartridge error message. Other error messages are not related. So in theory I’ve already solved this issue, when I updated my printer to the newest firmware early in the troubleshooting process. Both printheads give the same error message. This decreses my belief in buying new original ink to fix the problem…
EDIT 2: I found the old original HP empty cartridges I had before and installed them just to see if it would remove the error, but it didn’t. So now I don’t have to waste money on buying new ink at least…
Or am I missing something else? Thanks for helping out!

Have HP8600 and HP8610. One has a bad printhead. Can exchange good printhead between both and they will both work. Bought new printhead and recieved "missing, not detected or incorerectly installed" error. Tried everything without success. Was able to return printhead. Bought another printhead from other seller. Same problem! Now what HP??????

My experience as well. Have two of these printers. One works, one doesn't. Changing the good printhead to the other printer makes the error go away on the other. This is a printhead hardware failure, hands down. Haven't used OEM ink for years -- WAY overpriced. I also bought the eBay replacement printhead from China and it doesn't work. I'm assuming the sellers are collecting broken printheads that look good and calling them new?

I have the HP Officejet 8600 Pro, the first problem started with low yellow ink, I replaced then received error for other colors. I done everything everyone else had done but not luck. I bought a new print head, then received print head not detected. Put old print head and it's detected but shows bad ink cartridge despite being new from HP. So I took the top spring loaded ink holder from new print head and put that in my old print head and it worked.

I also have the office jet pro 8620 since a couple of years never had any issues and always bought original HP ink cartridges, same message “print head missing or incorrectly installed, thought because I didn’t use it for 7 months and the ink cartridges were very low so bought new HP original cartridges, same message.
Did everything, bought cleaning solution, did all of that, received same message. I gave up spent too much money afraid to order a new original print head, way too much money, therefore I bought another cheaper HP printer. It sucks really! Not too much help from HP!
