Greetings @Gavin5, 

Welcome to HP Forums and Thanks for the post. 

I understand that you are facing an issue with your printer where all the lights are flashing, is that right?

Kudos to you for trying to troubleshoot the issue on your own.

Not to worry, I will be glad to assist you. 

Are you using genuine HP ink?

Have you tried to restart the printer without the ink and check if the printer lights still blink?

Are you the lights blinking in a particular order?

Found this HP Article with the troubleshooting steps when the lights are flashing on your printer. 

Please try the steps based on the sequence in which the lights are flashing on your printer. 

Let me know how it goes.

Thanks for replying Chimney 83. 
All lights are blinking together with E flashing in the window!
I am using genuine HP ink. 

When setting up now, the computer doesnt seem to pick up the printer. 

Any suggestions on this? 

I have connected the printer to the router but it still doesnt show up!

Thanks
