The power switch is located on the left side of the machine.

While the machine is warming 
up, the START indicator will 
blink. (The START indicator 
will light up when the machine 
is ready to copy.)

If the power switch is turned off while the machine is in 
operation, a misfeed may occur and the job that was in 
progress will be cancelled.

The machine has two power save modes to reduce overall power consumption thereby reducing the cost of 
operation. In addition, these modes conserve natural resources and help reduce environmental pollution. The two 
power save modes are "Preheat mode" and "Auto power shut-off mode".

This function automatically switches the machine to a low power consumption state if the duration of time set in the system 
settings elapses without the machine being used when the power is on. In preheat mode the display turns off. Normal operation 
automatically resumes when a key on the operation panel is pressed, an original is placed, or a print job or fax is received.

This function automatically switches the machine to a state that consumes even less power than preheat mode if the 
duration of time set in the system settings elapses without the machine being used when the power is on. During auto 
power shut-off, only the [ENERGY SAVE] indicator (

) blinks. To restore the machine to normal operation, press the 

[ENERGY SAVE] key (

). Normal operation also resumes automatically when a print job or fax is received or 

scanning is begun from a computer. While auto power shut-off is in effect, pressing a key other than the [ENERGY 
SAVE] key (

) will have no effect.

The machine is set at the factory to return all settings to the default 
settings one minute after a copy job is finished (auto clear function) or 
when the [CA] key is pressed. When the settings return to the default 
settings, any functions that were selected are cancelled.
The auto clear time can be changed in the system settings. 

In the default state the display shown below appears. The default state of 
the display may vary depending on settings in the system settings.

• The machine reverts to the initial settings when it is first turned on, when the [CA] key is pressed, or when no 

keys are pressed for the preset "Auto clear" time following the end of a copy job. When the machine reverts to 
the initial settings, all settings and functions selected to that point are cancelled. The "Auto clear" time can be 
changed in the system settings. (p.179)

• The machine is initially set to automatically enter power save mode if not used for copying or printing, for a 

preset period of time. This setting can be changed in the system settings. (p.180)

• Before using fax mode, read the following sections and then turn on the power.

"TO USE THIS PRODUCT CORRECTLY AS A FACSIMILE" (p.79)
"POINTS TO CHECK AND PROGRAM AFTER INSTALLATION" (p.80)

The preheat activation time and the "Auto power shut-off timer" can be changed using system settings.
