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 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", Device Management.
To exit Fusing Unit Off mode, start print jobs.
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", Specifications.
Low Power mode
If you do not use the machine for a certain period after an operation, the display will turn off and the machine goes into Low Power mode. The machine uses less electricity in Low Power mode.
You can change the amount of time that the machine waits before switching to Low Power mode under [Low Power Mode Timer]. For details, see "System Settings", Device Management.
You can change the machine's settings to enter Low Power mode when you press the [Energy Saver] key. For details, see "System Settings", Device Management.
To exit Low Power mode, do one of the following:
Press the [Check Status] key
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", Device Management.
When the machine is in Sleep mode, only the [Energy Saver] key and the [Check Status] key are usable. The machine can print jobs from computers.
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", Device Management.
