The main power switch is on the left side of the machine. Turning off this switch makes the main power indicator on the right side of the control panel go off. When this is done, machine power is off. When the fax unit is installed, fax files in memory may be lost if you turn this switch off. Use this switch only when necessary.
This machine automatically enters Low Power mode or Sleep mode if you do not use it for a while. For details, see Saving Energy
