HP OfficeJet Pro 6978

This morning, I replaced all of my color cartridges on my OfficeJet 6978. Now, it will not print Cyan. 

I have tried a hard reset, cleaning the printer head, realigning the printer head, cleaning the connection between the cartridge and the printer, running diagnostic tests. I'm at a loss at what to try next. It worked fine until I replaced the cartridges this morning.
