HP OfficeJet Pro 6975 won’t print usig black ink.

[aacardenuto]

My HP OfficeJet Pro 6975 won’t print using black ink. Instead of printing anything, the printer just spits out blank pages. I had not replaced the cartridge before the printer started having this problem. However, I have replaced the cartridge two times after this problem started, so I know it cannot be a default with the ink. I have tried to clean the printhead multiple times. I also tried to clean them manually to no avail. I tried restarting the printer and did a Factory reset but neither of these things worked. I’m not sure what else I can do at this point. Has any one else successfully solved this problem?
