When you are using the fax function on the machine, do not turn the power off under normal operation. If the power is turned off, data stored in the fax memory will be lost in about one hour after the machine is turned off. If you have to turn the power off or unplug the power cord for some reason, make sure 100% is shown as available memory on the screen for the fax function.
Confirm how much power the options draw, and then plug them into an outlet that is nearby but separate from the outlet that the main machine is plugged into.

Energy Saving Mode
When the machine is not operated for a specified period of time, the machine enters the "Energy Saving mode" automatically. There are the following two steps of Energy Saving mode:
Low Power Mode
Sleep Mode
By default, the machine first switches to Low Power mode and then to Sleep mode after a lapse of time.
Low Power Mode
In this mode, the control panel display turns off and the main power indicator remains lit. If the machine is left idle for a specific time, it switches to Low Power mode.
You can change the amount of time that the machine waits before switching to Low Power mode under [Low Power Mode Timer].
If you touch the control panel in Low Power mode, the machine exits the mode and the control panel display turns on.
Sleep Mode
In this mode, the display of the control panel turns off and the main power indicator blinks slowly. Power consumption is minimized. When you do not operate the machine for a specified period of time or press [Energy Save] (
), the machine enters Sleep mode.
You can specify the amount of time that the machine waits before entering Sleep mode under [Sleep Mode Timer].
