Energy Saving Mode
When the machine is not operated for a specified period of time, the machine enters the
"Energy Saving mode" automatically. "Energy Saving mode" has two modes, "Fusing Unit
Off mode" and "Sleep mode", and the machine enters the Fusing Unit Off mode first. In
the factory default, the machine is configured to use both modes.
Fusing Unit Off Mode
In this mode, the main power indicator is lit. Because the heater of the fusing unit is
turned off but the screen of the control panel is still displayed, the power
consumption decreases, but you can start operation promptly. If you do not operate
the machine for a specified period of time, the machine emits a clicking sound and
enters Fusing Unit Off mode.
• You can specify whether to enable the Fusing Unit Off mode and the time to
wait before the machine enters Fusing Unit Off mode under [Fusing Unit Off
Mode (Energy Saving) On/Off].
See "Date/Time/Timer", User Guide (HTML).
• In this mode, you can scan documents, send faxes, receive faxes into memory,
change the machine settings on the control panel, and perform other operations
that do not require printing.
Sleep Mode
In this mode, the display of the control panel turns off and the main power indicator
blinks slowly. Power consumption is minimized. When you do not operate the
machine for a specified period of time or press [Energy Save] ( ), the machine
enters Sleep mode.
• You can specify the amount of time that the machine waits before entering
Sleep mode under [Sleep Mode Timer].
See "Date/Time/Timer", User Guide (HTML).
• The machine recovers from Sleep mode when you perform one of the following:
• Lift the ADF or exposure glass cover.
• Place an original in the ADF.
• Touch the display of the control panel.
• The energy saving functions are disabled when an error occurs or while an operation
is in progress.
• The energy saving functions will not operate in the following cases:
• When fixed warm-up is in progress
• When operations are suspended during printing
• When a warning message appears (The machine enters Fusing Unit Off mode
unless the cover is open.)
