All printer lights flashing like a crazy disco, unresponsive

[Vennard]

Please see video of the issue...

Printer was just left idle, as it always is

Came up to bed to find it flashing like crazy

Printer was unresponsive to button press, main cover open, etc. 

Power cycle brought it back to normal operation

Printer had not been used for 2 days

Has anyone seen this before or do we have a faulty unit 

This is the second time it has played up while being left idle

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help,

I am glad to know that you managed to resolve the issue. This could be happening due to a software driver issue.

• Let's try these steps to resolve the issue:

Download and run HP Print and Scan Doctor: Follow steps from the link: Click here

Root level uninstall and reinstall printer drivers: 

• Go to Control panel – Programs and feature – Select all the HP Envy printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.

And, also update the printer firmware: https://support.hp.com/us-en/document/ish_1776648-1643972-16
