Entering Sleep Mode

The sleep mode function reduces the amount of power consumed by the machine by disabling power flow to the

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>(P. 455) ) 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.
