HP ENVY 5020 not printing black ink properly

[bbping]

I am having issues with black ink printing where there are lines across the page not being printed. I have tried the troubleshooting print quality issues and they all don't seem to work. I started using the printer not long ago and I'm already just left with less than half a cartridge. But it has enough ink in the cartridge to be able to print the page properly. Please help otherwise I will have to try a new cartridge or a new printer altogether. Many thanks

Hi,

I have tried all the solutions suggested and it doesn't seem to solve the issue. Plus now, when I do the quality test pages, the blue colour seems to have disappeared. Please help.

Thanks so much
