# Saving Energy

This section explains the machine's energy saving functions.

This machine has the following energy saving functions.

Energy Saver

If you do not use the machine for a certain period after an operation, or when you press the [Energy Saver] key, the display disappears and the machine goes into Energy Saver mode. When you press the [Energy Saver] key again, the machine returns to the ready condition. The machine uses less electricity in Energy Saver mode.

You can change the amount of time the machine waits before switching to Energy Saver mode after copying has finished or the last operation is performed under Panel Off Timer.

Auto Off

If the machine remains inactive for a specified period, it automatically enters the same low power state that it enters when the operation switch is pressed (indicator unlit). This function is called “Auto Off”.

You can change the Auto Off time under Auto Off Timer.

- See “System Settings”, Network and System Settings Reference.
