How do I reset the HP Color LaserJet Managed MFP E47528 to factory settings?

There are two methods to reset factory settings. Method one is from the printer control panel, and Method two is from the HP Embedded Web Server (for network-connected printers only). The Reset button on the control panel can also be used to clear changes, release the printer from a paused state, and restore default settings including language and keyboard layout. (Page 128-129)
