Can't finalize set-up, error message E3. I've checked all possibilities I could find

OK bought printer brand new, unboxed it per instructions. Connected to WiFi no problem, but I can't finalize it. Keep getting flashing "resume" light and "X" light, and nothing is working

Hi @TxMOJOROX,

Welcome to the HP Support Community.

I'd be happy to help.

Let's try to reset the Printer here:

Reset the product

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

Also, try connecting the Printer to a different wall outlet directly.

Try a firmware update: https://support.hp.com/us-en/document/ish_1776648-1643972-16
