I have not had this printer very long, but recently the black ink was low. I replaced it with the correct black cartridge that the printer requires, yet it will NOT print black at all.
I returned the ink and bought a new one - and same problem. I have also followed the troubleshooting advice that I have seen given to others with the same problem, but cleaning the printhead and cleaning paper-smear has done nothing to fix the problem. (It wasted plenty of paper and other ink cartridges, however!)
Upon seeing that this appears to be a common issue with the OfficeJet 6978, I checked my warranty which has conveniently expired. (Is the warranty now less than a year?!)
I am quite upset that the printer is less than 2 years old and is already nothing but an expensive paperweight with fresh, new ink. I had purchased this printer to replace an older HP printer that was having problems -- only now I wish I had gone with any other brand!
I think it's TERRIBLE that this appears to be a known issue and yet the only way to resolve it is to send it in and pay for something that is the manufacturers fault. If this cannot be fixed, I am never buying another HP product again.
I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).
