This older post expresses the same issue that I'm having. When I print pink streaks show up where it should be blue. I have cleaned the print head twice and there is no issue demonstrated in that print out (looks clear). I have replaced the ink cartridges. I have aligned the print head. Everything listed in this page has been done. The problem persists.
Thank you for the detailed response. Since you have already tried all the possible troubleshooting steps, this seems like a hardware issue with the printhead of the printer. Please reach out to the HP Technical Support team in your region regarding the service options for your printer.
If the printer is out of warranty, I suggest you upgrade the printer. You may visit Hp Store to check the available printers.
