Hi @Envy-6400-leds,

Welcome to the HP Support Community. 

I'd like to help!

I understand all the lights on the printer are flashing

Try the below suggestions -

 Reset the product

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

Try updating the printer's firmware -HP Printers - Updating or Upgrading Printer Firmware

Also, try the steps in the document

If the issue persists, this could be a hardware issue. 

Hope this helps! Keep me posted
