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", Settings.
To exit Fusing Unit Off mode, do one of the following:
Start print jobs
