Saving Energy

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, send faxes, receive faxes into memory, 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 "Timer 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 when the Copier screen is displayed

  • Open the front cover, rear cover, or a tray.

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 [Energy Saver] (Operation panel screen illustration) is pressed, it enters Sleep mode to further reduce the electricity it consumes. For details, see "System Settings", Connecting the Machine/ System Settings.

You can change the amount of time that the machine waits before switching to Sleep mode under [Sleep Mode Timer]. For details, see "Timer Settings", Connecting the Machine/ System Settings.

  • Lift the ADF

  • Place an original in the ADF
