My officejet pro 6978 will not print black even though cartridge indicates nearly full

HP officejet pro 6978
Microsoft Windows 7 (64-bit)

My Officejet Pro 6978 quit printing black even though the black cartridge indicates nearly full. All color cartridges also indicate nearly full and are printing fine. Only the black quit working in both print and copy modes. This is the second time this has happened. The first time I replaced the black cartridge with an HP 902XL and the printer began printing normally again. Receiving ink cartridges  from HP Instant Ink program.
