Entering Sleep Mode
0W20-016
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.

When You Want to Set the Auto Sleep Timer
The factory default setting for the amount of time that elapses before the machine enters auto sleep mode is 3
minutes (the user setting range is 3 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 the machine enters auto sleep
mode, follow the procedure below.
