Change the time required to automatically change to Low Power mode after you have not operated this machine for a fixed period of time.
In Low Power mode, the display of the Touch Panel is turned off to reduce power consumption.

[15] minute is specified by default (allowable range: [2] to [240] min.).

Change the time required before the machine automatically enter Sleep mode if you have not operated this machine.
Sleep mode provides a greater power saving effect than Low Power mode. However, the time required to return to the normal mode is longer than the time required to recover from Low Power mode.

[20] minute is specified by default (allowable range: [2] to [240] min.).

Select whether to use the Power key on the Control Panel as a sub power OFF key or as a power save key.
[Sub Power OFF]: Press the Power key to turn the sub power off. If the Power key is held down, Power Save mode shifts to ErP Auto Power Off mode (close to Main Power Off mode), which offers a higher power saving effect than Sub Power Off mode.
[Power Save]: Press the Power key to shift to Power Save mode (Low Power or Sleep mode). Hold down the Power key to shift to sub power off mode.

[Sub Power OFF] is specified by default.

If [Power Save] is selected for [Power Key Setting], select the type of Power Save mode you want to switch when pressing the Power key on
the Control Panel.
[Low Power]: Switches to Low Power mode. Turns off the display of the Touch Panel to reduce power consumption.
[Sleep]: Switches to the Sleep mode. Sleep mode provides a greater power saving effect than Low Power mode. However, the time required to return to the normal mode is longer than the time required to recover from Low Power mode.

[Low Power] is specified by default.

Select the timing for the machine to return to the Power Save mode after printing a job it has received in the Power Save mode from a fax machine or computer.
[Normal]: Switches to Power Save mode based on the time specified in [Low Power Mode Settings] or [Sleep Mode Settings].
[Immediately]: Switches to Power Save mode immediately after a print job has ended.

[Immediately] is specified by default.

Select whether to reduce power consumption in the Sleep mode. 
[Enabled]: Further reduces power consumption in Sleep mode. Usually, select [Enabled].
[Disabled]: Select this option when a smooth network communication is not established while [Enabled] is enabled.

[Enabled] is specified by default.

Select whether to give priority to the power saving when the machine returns from Sleep or sub power off mode to a mode other than copy mode. When returning to a mode that does not involve printing, such as scan/fax mode, power consumption can be reduced by not adjusting the temperature of the Fusing Unit on this machine.

You can set this option when you have selected an option other than [Copy] in [Priority Mode] that is selected by [Administrator Settings] - [System Settings] - [Reset Settings] - [System Auto Reset].
[Power Save]: The temperature of Fusing Unit is not adjusted when the machine returns to the normal mode.
[Standard]: The temperature of Fusing Unit is adjusted when the machine returns to the normal mode.

[Standard] is specified by default.

Select whether to return to the normal mode without touching the Touch Panel when the machine is in Low Power mode or Sleep mode.
If you select [ON], you can adjust the sensitivity of the sensor.

Selecting a setting on the minus side decreases the sensitivity (shortens the sensing distance).

Selecting a setting on the positive side increases the sensitivity (lengthens the sensing distance).

[ON] is selected by default. The adjustment value is [0].

Change the time required to automatically shift to the Low Power mode after you did not operate this machine (default: [15] minutes, available range: [2] to [60] minutes).

In the Low Power mode, the display of the Touch Panel is turned off to reduce power consumption.

Change the time required to automatically shift to the Sleep mode after you did not operate this machine (default: [15] minutes, available range: [2] to [60] minutes).

Sleep mode provides a greater power saving effect than the Low Power mode. However, the time required to return to the normal mode is longer than the time required to recover from the Low Power mode.

Select whether to reduce the power consumption in the Sleep mode (default: [High]).

[High]: Further reduces the power consumption in the Sleep mode. However, this machine cannot be returned from the Sleep mode when the door of the main unit is opened or closed or when the original is loaded.
[Enabled]: Reduces the power consumption in the Sleep mode.
[Disabled]: Select this option when a smooth network communication is not established while [High] or [Enabled] is enabled.

Select whether to use the Power key on the Control Panel as a sub power OFF key or as a power save key (default: [Power Save]).

[Sub Power OFF]: Press the Power key briefly to turn the sub power off. If the Power key is held down, the power save mode is switched to the ErP Auto Power Off mode (similar to main power off mode), which provides a greater power saving effect than when the sub power is turned off.
[Power Save]: Press the Power key briefly to shift to the Power Save mode. Hold down the Power key to turn the sub power off.

When this machine receives a print job from a fax machine or computer in the Power Save mode, select the timing to switch to the Power Save mode after the print job has ended (default: [Immediately]).

[Normal]: Switches to the Power Save mode based on the time specified in [Low Power Mode Setting] or [Sleep Mode Setting].
[Immediately]: Switches to the Power Save mode immediately after a print job has ended.

Select whether to give priority to the power saving when returning from the Sleep or sub power off mode to a mode other than the copy mode (default: [Standard]).

When returning to a mode that does not involve printing, such as scan/fax mode, power consumption can be reduced by not adjusting the temperature of the Fusing Unit on this machine.

This option is available when an item other than [Copy] is selected in [Start-up display screen after reset] of [System auto reset] 

[Power Save]: The temperature of Fusing Unit is not adjusted when the machine returns to the normal mode.
[Standard]: The temperature of Fusing Unit is adjusted when the machine returns to the normal mode.

When recovering the machine from Power Save mode when a user moves closer to the Touch Panel, set this option to ON (default: [ON]).

[Touch sensitivity adjustment]: Specify the sensitivity of Touch Panel reaction (default: [0]). The higher the number, the greater the sensitivity and reaction speed will be of the touch panel.
