Fix OfficeJet Pro error code 0xc19a0042

[ghostlyyyyyy]

I've scrubbed the Internet and these community help forums but haven't found an adequate solution to error code 0xc19a0042 on my OfficeJet Pro 6975. Upon restart and after thorough print head cleaning and new print cartridges, still getting error: "There is a problem with the printhead. 0xc19a0042" on the screen. Before this error, we replaced print cartridges with genuine HP cartridges. Color ink printed fine but no black ink.
