HP 6978 won't print black ink

[J-Cal]

I'm having the same issue. Unbelievable. The thing has one job. Print black. Nope. I have followed the steps. Reinstalled cartidges, bought new cartridges, and still nothing. I don't have time for this. Now i'm going to be unprepared for work. Unacceptable.

: UPDATE :

   For every other poor soul that's going through this. I discovered that my problem may be the printer's compatability issue with Excel. I have successfully printed from another program. For the meantime what I have been doing is printing the pages I want to pdf's through excel, and then just printing them. WhileI can't decide if it's printing a touch light, it does seem to be working for now. I have printed multiple pages successfully.

   For everyone's info, I am on a Mac running  OSX 10.11.6 and excel version 12.3.6

I did the hard re set. I then did a copy to see if the Black print would happen. No Luck.
