Energy Saving Features
You can conserve power efficiently when the machine is not being used by using the following modes.
IMPORTANT
Even if the main power switch is turned OFF, a small amount of energy is consumed if the power plug is left inserted into the power outlet. If you do not want any energy consumed, remove the power plug from the power outlet.
NOTE
The touch panel display turns OFF when the machine enters one of the energy saving modes.
The machine can continue to receive I-fax or fax documents, and process or print data sent from computers even if it is in one of the energy saving modes described below.
Energy Saver Mode
The Energy Saver mode conserves energy by lowering the temperature of the fixing unit when the machine is not used for a prolonged period of time. You can set the machine to enter the Energy Saver mode by pressing  on the control panel. To reactivate the machine, press  again. You can also press the control panel power switch to reactivate the machine.
NOTE
The Energy Saver mode's energy conservation level can be set to '-10 %', '-25 %', '-50 %', or 'Zero Restore Time'. The default setting is '-10 %'. (See, "Change Energy Saver Mode.")
Auto Sleep Mode
You can set the machine to enter the Sleep mode whenever you desire, by pressing the control panel power switch, or specify to have the machine enter the Sleep mode at a preset time. To reactivate the machine, press the control panel power switch again.
NOTE
The machine may not enter the Sleep mode completely depending on certain conditions. (For more information, see "Energy Consumption in the Sleep Mode.")
Turn the control panel power switch OFF when not using the machine for a prolonged period of time, for example, at night.
If a Macintosh, which has been shut down, is connected to the machine via a USB cable, when you turn the machine ON, the Macintosh may also turn ON. In this case, disconnect the Macintosh from the machine. (You may also be able to solve this problem by using a USB hub between the machine and the Macintosh).
The time it takes for the machine to automatically enter the Sleep mode can be set from 10 seconds to 4 hours. The default setting is '1' minute. (See "Auto Sleep Time.")
If Sleep Mode Energy Use is set to 'Low', it may take approximately 10 seconds for the touch panel to be displayed after pressing the control panel power switch.(See "Energy Consumption in the Sleep Mode.")
Weekly Timer
The machine automatically enters the Sleep mode at the specified time and day of the week set with the weekly timer. To reactivate the machine, press the control panel power switch.
NOTE
The Weekly Timer Settings can be set from Sunday to Saturday and 00:00 to 23:59. (See "Weekly Timer Settings.")
