Hi @Spipon,

Welcome to HP Forums, this is a great place to get support, find answers and tips.

Thank you for posting your query, I'll be more than glad to help you.

I understand that you are facing print quality issues with your HP ENVY 4520 All-in-One Printer.


This issue could occur if the ink nozzles on the cartridge are clogged.


Let's go through a few steps that may help to fix this issue.


And here are a few steps for you in the link: Fixing Print Quality Problems


Also, you may remove one of the cartridges, print a page and then swap it with the other cartridges and check if it is the same issue with both the cartridges when they are installed one at a time.


Let me know how this works.


You have a good day ahead.
