I have been using HP8620 for few years now.
A month ago I started having "Missing or failed printhead"
First i tried to upgrade firmware but it seems I have latest one .
I bought new heads and replaced them yet it did not help
Tried removing and inserting heads again.....yet I get the same message
Tried to clean the contacts while doing the following procedure :
Yet I get the same error ......
in the printer dashboard the ink levels shows full .
Any suggestions ?

To the matter of truth it happened while using a genuine hp cartridges which I always used since I purchased the printer .
I dont want to spend ~100 usd and toss is to trash.
