Restore the factory-set defaults
Restoring the factory-set defaults returns all of the printer and network settings to the factory defaults. It 
will not reset the page count, or tray size. To restore the printer to the factory-default settings, follow these 
steps.
CAUTION:
Restoring the factory-set defaults returns all of the settings to the factory defaults, and it also 
deletes any pages that are stored in the memory.
1.
On the printer control panel, press the 
OK
button.
2.
Select Service.
