If the scanner is left powered on for 15 minutes (factory default setting) or more without being used, it automatically enters power saving mode.

When it enters power saving mode, the LCD on the operator panel turns off. The power button remains lit in blue.

To resume from power saving mode, perform one of the following:

• Load a document on the hopper.

• Press any button (except for power button) on the operator panel.

  Note that the scanner will be turned off when you press the power button for more than two seconds.

• Scan a document with the image scanning application.

Also, the scanner can be set to turn itself off automatically when it is turned on and left unused for a certain period of time.

You can save the power consumption by having the scanner turn off automatically.

To enable this setting, select the [Power off after a certain period of time] check box in [Device Setting] of the Software Operation Panel. When the [Power off after a certain period of time] check box is cleared, the scanner's energy consumption will increase.

For details, refer to Setting the Waiting Time to Enter Power Saving Mode [Power saving].

To turn the scanner back on after it is automatically turned off, press the power button on the scanner.

For details, refer to How to Turn the Power ON.
