How do I restart Wi-Fi setup mode if the printer's wireless setup mode has timed out?

First, if the control panel is not lit, press the Power button to exit sleep mode. Then press and hold the Wireless button for 5 seconds and release it so all control panel buttons light up, then press the Wireless and Information buttons at the same time once and release them — the Wireless light will blink blue. Wait one minute, then close and reopen HP Smart and try connecting again. (Page 3)
