Operating System: Microsoft Windows 10 (64-bit)

I recently had my HP Envy Pro 6400 start blinking ALL of its lights randomly and freaking out, not even detected by the PC. Unplugging and other things did not help. I was told by a technician on the online chat function how to fix it. This is not published, so I hope this helps someone because it was all that cured mine, saving me from having to replace it under warranty. The message was as follows:
Unplug the power cord. Reconnect the power cord, while the printer is powering on, press and hold the "POWER BUTTON" until LED LIGHT in front comes on. Once the led lights up, press and hold the "POWER & INFO BUTTON" till the the LED LIGHT turns off. (The LED will remain lit up for 4 seconds).

Give that a try and see if it fixes the issue you may have like mine.

 

Thanks.
