How do I remove the print head from the 3521 model to clean it?

[Lucygoo]

My black ink won’t print so it’s been suggested that I remove the print head and clean it under running water, but I can’t figure out how to remove it. It’s attached to the printer with a white band.

Thank you for joining the HP Community

Thie printhead on HP Deskjet 3520 Printers is not a removable part.

Clean the printhead automatically

Run an automatic utility to clean the printhead.

1. Load plain, white paper into the paper tray.

2. On the printer control panel, press the Down Arrow  to select Settings, and then press OK.

3. Press the Down Arrow to select Tools, and then press OK.

4. Press the Down Arrow to select Clean Printhead, and then press OK.

   The printer cleans the printhead, and then prints a test page.

5. Review the print quality on the test page.

Apparently HP still has no solution for this problem.  I have searched back to 2014 and all of the answers have been the same - and none of them has worked.  All I've found is people who are fed up and throwing away their printers.  Mine has worked great for 5 years and I really don't want to dump it just because the black ink stopped printing.  Any other suggestions as I have tried everything here multiple times - cleaning printheads, realigning printheads - doesn't work because black does not print, only colors - cleaning the vent, replacing cartridges - nothing works.  Why would this happen suddenly when everything has been working perfectly for years?
