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. You can also use the Auto Sleep Time setting to automatically put the machine into sleep mode if it remains idle for a specified length of time. You can specify settings to change the interval at which the auto sleep function is performed or put the machine in sleep mode at a specified time.

Situations in which the machine does not enter sleep mode

Selecting the Sleep Mode Level
Sleep mode can be set to 2 different levels with different energy consumption reduction effects. The factory default setting for sleep mode level is <High (Deep Sleep)>. We recommend using the factory default setting to save the most power. If you want to change the setting, follow the procedure below.

Changing Auto Sleep Time
When the sleep mode level is set to other than <Off>, the machine automatically enters sleep mode if it remains idle for a specified length of time. The factory default setting for the amount of time that elapses before Auto Sleep is performed is 5 minutes (the user setting range is 5 to 60 minutes). We recommend using the factory default settings to save the most power. If you want to change the amount of time that elapses before Auto Sleep is performed, follow the procedure below.
