Error code -9 when setting up a new Printer

[fdhshdyjj]

Hello, I am using HP Smart to setup a new printer (HP ENVY Inspire 7921e All-in-One Printer) when I get to the wifi connection setup I am getting the error code -9 and the message Unable to connect to Wi-Fi network.

I already tried the turn off and on again on the printer and router.

Hi @fdhshdyjj,

Welcome to the HP Support Community

I understand you are facing a Wi- Fi issue with your HP ENVY Inspire 7921e All-in-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle
