HP Envy 5020 Printing issue

[jo5030]

My Envy 5020 has suddenly started to have a printing issue.  It hase new cartridges but the colour printing - especially Yellow - is very poor or non-existent.  I have aligned, cleaned and deep cleaned the heads, but I still get the same problems.  These occure whether I print from my PC or as part of the printer test suite.  I have reverted tjhe printer to factory settings - same results

Before I throw it in the bin, any suggestions (it is only a couple of years old, and gets little use)

I attach a couple of pictures to show the results of various diagnostic prints (I would have used .pdfs but there seemed

to be no way to attach one )

Welcome to the HP Support Community.

Do you have any other yellow ink to check if this is an issue with the current yellow ink?

Try a firmware update: https://support.hp.com/in-en/document/c02919168
