had to buy new black ink cartridge; now I can't get the black to print
Product: HP OfficeJet Pro 6970
Operating System: Microsoft Windows 10 (32-bit)
I have cleaned the print heads multiple times; I am not getting any error messages; the ink shows that they are full. I have gone through the HP program; had the laptop do the check of the system; ran the various checks; when I printed the sheet to check status, I only get gray tones; no black, ditto for checking alignment. When I print anything, unless there is color on the sheet for anything, it is completely blank. I have tried to print documents, PDF's from emails, etc. All blank. My printer is 2-3 years old; in a vacation home so not used extraneously. We have managed to go through a significant amount of ink, but think living part-time in AZ, it might be the heat that dries up the ink?? I did obtain more black ink, but for the $$$ would like to be able to get the current NEW ink cartridge to work. The printer did work fine until ran out of black ink. Suggestions??
