Restoring factory default settings
If you want to keep a list of the current menu settings for reference, then print a menu settings page before restoring
the factory default settings. For more information, see “Printing a menu settings page” on page 114.
If you want a more comprehensive method of restoring the printer factory default settings, then perform the Wipe All
Settings option. For more information, see “Erasing non‑volatile memory” on page 119.
Warning—Potential Damage: Restoring factory defaults returns most printer settings to the original factory default
settings. Exceptions include the display language, custom sizes and messages, and network/port menu settings. All
downloads stored in the RAM are deleted. Downloads stored in the flash memory or in a printer hard disk are not
affected.
From the home screen, navigate to:
> Settings > General Settings > Factory Defaults > Restore Now >
