4 HOURS Use this item to set how long the MFP remains idle before it enters
Sleep mode. Sleep mode minimizes the amount of power that the
MFP consumes when it is idle and reduces wear on the MFP
electronic components (turns off the display backlight).
When you send a private job, press the control-panel key, open a
tray, or open the top cover, the MFP automatically exits Sleep
mode.
Note
Sleep mode turns off the backlight on the display, but the display
can still be read.
