Trying to set my HP Envy 6455 printer to the original factory settings

[Perledo]

I am trying to restore the factory settings on my HP Envy 6455 Printer.  Raising the cartridge door and pushing the power button and the button in the back of the printer for three seconds did not work.   Noe I am getting a flashing      E 9 error message

Hi @Perledo,

I'd like to help!

I understand you are receiving an E9 error.

An E9 error occurs when there is a setup or update error.

Check the HP Smart app to confirm the error. If a Printer Setup Incomplete message displays, restore factory defaults on the printer, and then add the printer to HP Smart again. For detailed steps, go to HP ENVY 6000e, 6400e printers - E9 (Printer Setup Incomplete) error.

If a message does not display in HP Smart, a problem occurred during a printer firmware update. Continue with these steps.

1. Set up the wireless connection again.

   Go to Wireless Printer Setup for more information.

2. Touch the Information button  on the printer.

   If an information page prints, the issue is resolved.

   If an information page does not print, the printer is in recovery mode and needs to download the firmware again.

   NOTE: 

   During recovery mode, the printer automatically downloads firmware from the cloud. Leave the printer for about 2 hours, depending on your network speed, to complete the firmware update.

Also, refer to the document -Blinking Lights and Error Codes

Hope this helps! Keep me posted.
