Restoring the factory-set defaults returns most of the settings to the factory defaults. It will not reset the page count, tray size, or language. To restore the product to the factory-default settings, follow these steps.
Turn the product off. Disconnect the power cable from the product for 30 seconds and then reconnect.
Turn the product on while you press and hold the Resume button for 10-20 seconds. The Attention light turns on.
Release the Resume button. The Attention and Ready lights cycle while the product restores factory defaults.
