HP Envy 4520 Printer not printing with quality

[ajm1768]

I have reset, run diagnostics, and cleaned the ink using the method outlined here: https://h30434.www3.hp.com/t5/Printing-Errors-or-Lights-Stuck-Print-Jobs/HP-Envy-4520-printing-blank....  When printing from my computer (windows 10), phone (iOS), or even just copying a page directly from the printer, the print quality is poor.  In many places, it just prints blank.  I checked the ink levels and they are not low.  I have also tried changing the ink (using HP ink).  When doing test pages, there is one spot on the page that prints fine, the rest of the page either is very faded/streaky or not there at all.  I also have run all updates on my computer and from the printer.  Please help me troubleshoot so I can get this issue resolved.
