HP Deskjet Ink Advantage 2645
Microsoft Windows 10 (64-bit)

I have an HP Deskjet 2645 and as much as possible, I buy original cartridges. However a few weeks ago, I am getting an error suddenly that my black ink cartridge is "incompatible" even though that cartridge was working fine before it happened and I always make sure I buy the exact model. I tried to do everything, including buying a new black ink cartridge but all of them did not work. What the hell happened and can you fix this? Otherwise, do I have to throw the printer in the garbage it has been a frustrating experience and I am losing my patience with this issue!
