Entering Sleep Mode

The sleep mode function reduces the amount of power consumed by the machine by disabling power flow to the operation panel. If no operations will be performed on the machine for a while, such as during a lunch break, you can save power simply by pressing  on the operation panel.

Changing the Auto Sleep Time Value
Auto Sleep Time is a function that automatically puts the machine into the sleep mode if it remains idle for a specified length of time. We recommend using the factory default settings (<Timer/Energy Settings>) to reduce power usage. If you want to change the amount of time that elapses before the machine enters the auto sleep mode, perform the procedure below.
<Menu>  <Preferences> <Timer/Energy Settings>  <Auto Sleep Time>  Set the amount of time that elapses before the machine automatically enters sleep mode  <Apply>  
Changing the Sleep Mode Setting to the Specified Time
You can configure a setting so that the machine is placed into the sleep mode at the specified time. You can also configure a setting so that the sleep mode is released at the specified time.
<Menu> <Preferences> <Timer/Energy Settings> Select <Auto Sleep Daily Timer> or <Sleep Mode Exit Time Settings> Select <On> in <Set This Function>, and enter the time <Apply>  
Exiting Sleep Mode
You can press  or any other key on the operation panel to exit the sleep mode.
You can also tap the display to exit sleep mode.
