The Service menu is used to calibrate, restore factory default settings, and clean the print paper path.
The following Service menu items are available:

●Cleaning Page—used to remove dust and toner from the print paper path
●PowerSave Time—used to configure the amount of idle time before the engine enters sleep mode
●USB Speed—used to set the USB speed
●Less Paper Curl—used to decrease the fuser temperature, which can reduce paper curl
●Archive Print—used to decrease the likelihood of toner smearing on a print job
●Restore Defaults—used to reset all customer-accessible menu settings back to the factory default settings (except language) via the control panel or software
NOTE: This menu item does not reset factory-settable settings, including formatter number, page counts, factory paper settings, language, and so on.
