Product: Officejet Pro 6978
Operating System: Microsoft Windows 10 (64-bit)
Stopped printing. I replaced all 4 ink cartridges. Still says 'printhead problem'.
There is not a release lever on right of ink cartridge carrier so I don't know how to remove the printhead
it's an Officejet Pro 6978 bought new in Sept 2016. Printhead part #CN643A
Is it time to buy a new printer?
