Printer is printing blue instead of black

[TimWJ]

My printer prints a light blue in places that should be black. If i choose to print only in grey scale it prints a blank page. 
I've changed the cartridge but this didnt help. 
My printer is a hp envy 5030 

I'm printing pdf files

Hi @TimWJ

Welcome to the HP Support Community. I'd be happy to assist you with the printing issue. 

To better assist you - 

1) Does tcpy works? 

2) What's the application you are trying to print from? Have you tried printing from a different application or devices? 

While you respond to that, let's print a Print Quality Diagnostic page - 

1. Load the printer with plain white paper.

2. On the printer control panel, swipe left on the display, and then touch Setup .

3. Touch Tools.

4. Swipe up on the display, and then touch Print Quality Report.

Post the Print Quality Diagnostic page here so we can help you further. 

You may also refer to this document - Print Quality Issue

Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

Hope this helps! Keep me posted.
