Turning On and Off the Power
To turn the machine on and off, press the main power switch on the front right side of the machine.
Do not press the main power switch repeatedly. When you turn the power on or off, wait at least 10 seconds after confirming that the main power indicator on the right side of the control panel has turned on or off.
Make sure the power cord is firmly plugged into the wall outlet.
Open the cover of the main power switch on the front right side of the machine, and push the switch.
The main power indicator on the right side of the control panel turns on.
When the power is turned on, the screen may show that the machine is performing an auto restart. Do not turn off the main power while the machine is processing. It takes about 5 minutes until the machine restarts.
Do not turn off the power while the machine is in operation. To turn the power off, confirm that the operation is finished.
Do not hold down the main power switch while turning off the main power. Doing so forcibly turns off the machine's power and may damage the internal storage or memory and cause malfunctions.

The main power indicator on the right side of the control panel turns off. The main power turns off automatically after the machine has shut down properly.
When the machine is not operated for a specified period of time, the machine enters the "Energy Saving mode" automatically. "Energy Saving mode" has two modes, "Fusing Unit Off mode" and "Sleep mode", and the machine enters the Fusing Unit Off mode first. In the factory default, the machine is configured to use both modes.
Fusing Unit Off Mode
In this mode, the main power indicator is lit. Because the heater of the fusing unit is turned off but the screen of the control panel is still displayed, the power consumption decreases, but you can start operation promptly. If you do not operate the machine for a specified period of time, the machine emits a clicking sound and enters Fusing Unit Off mode.
You can specify whether to enable the Fusing Unit Off mode and the time to wait before the machine enters Fusing Unit Off mode under [Fusing Unit Off Mode (Energy Saving) On/Off].
In this mode, you can change the machine settings on the control panel, and perform other operations that do not require printing.
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].
The machine recovers from Sleep mode when you touch the display of the control panel.

The energy saving functions will not operate in the following cases:
