This machine has the following energy saving functions.
Fusing Unit Off mode
If you do not use the machine for a certain period after an operation, the machine makes a clicking sound and enters Fusing Unit Off mode.
When the machine is in Fusing Unit Off mode, the display is on but the fusing unit heater is off to save energy. In this mode, you can scan documents, receive faxes, and change the machine's settings on the control panel. However, the machine must exit this mode to print.
You can change the amount of time that the machine waits before switching to Fusing Unit Off mode under [Fusing Unit Off Mode (Energy Saving) On/Off]. For details, see "System Settings", Connecting the Machine/ System Settings.
To exit Fusing Unit Off mode, do one of the following:
Start print jobs
Switch to the [Copier] screen
Touch the display panel or press one of the keys on the control panel when the [Copier] screen is displayed
The time required to return from Fusing Unit Off mode and resume printing is as long as the time required for warm-up time. For details about the warm-up time, see Specifications for the Main Unit.
Sleep mode
If the machine remains inactive for a specified period or the [Energy Saver] key is pressed, it enters Sleep mode to further reduce the electricity it consumes. For details, see "System Settings", Connecting the Machine/ System Settings.
When the machine with the standard operation panel is in Sleep mode, only the [Energy Saver] key and the [Check Status] key are usable. The machine can print jobs from computers and receive faxes.
You can change the amount of time that the machine waits before switching to Sleep mode under [Sleep Mode Timer]. For details, see "System Settings", Connecting the Machine/ System Settings.
