How does the Auto-Off feature work and when is it enabled or disabled?

The Auto-Off feature turns the printer off after 2 hours of inactivity to help reduce energy use, and you must use the Power button to turn the printer back on. Auto-Off is automatically enabled when the printer is turned on and does not have network, fax, or Wi-Fi Direct capability, or is not using these capabilities. Auto-Off is disabled when a printer's wireless or Wi-Fi Direct capability is turned on or when a printer with fax, USB, or Ethernet network capability establishes one of those connections. (Page 21)
