Hi @Drewster1,

Welcome to the HP Support Community. 

I understand that you are getting printers not enrolled and the power button flashing.  I'd like to help!

To assist you better, I would need a few details. 

Are you enrolled in instant ink?

Are you getting any errors/codes?

The power light blinks fast

The Power light blinks fast when the ink cartridge door is open, or the printer is in an error state.

If an error message displays on the computer or mobile device, follow any steps to resolve the issue.

If the ink cartridge door is open, close it.

If the ink cartridge door is closed, try printing a document to generate a message.

You may also refer to this document here and see how it goes. 

Please try these steps -

1) Take out the cartridges.

2) Unplug the power cord from the printer & wall.

3) Wait for 30 seconds. 

4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector.

5) Insert the cartridges back into the printer.

Also, try updating the printer's firmware - https://support.hp.com/in-en/document/c02919168

If the issue still persists, try rebooting the router and the printer.

Hope this helps! Keep me posted for further assistance.
