How to Turn ON the Main Power

This section explains how to turn ON the main power.
1.
Make sure that the power plug is firmly inserted into the power outlet.
WARNING
Do not connect or disconnect the power cord with wet hands, as this may result in electrical shock.
2.
Turn ON the main power.
1. Open the main power switch cover.
2. Press the main power switch to the "I" side.
The main power indicator on the control panel lights when you turn ON the main power switch.
Various screens appear when system software is loading.
NOTE
You can change the default display that appears after the machine is turned ON from [Default Screen after Startup/Restoration] on the Settings/Registration screen. (See "Default Screen after Startup/Restoration.")
The response of the buttons and keys may not be optimal immediately after you turn ON the main power of the machine.
If you set Department ID Management, see "Entering the Department ID and PIN."

Energy Saver Key

If the machine is idle for a certain period of time, the machine will enter the Auto Sleep mode to minimize energy consumption.
Press (Energy Saver) to cancel the Sleep mode and resume normal machine operations.

Shutting Down the Machine

This machine performs a procedure to protect the hard disk when the machine is shut down.
This enables the machine to be shut down safely, even if there are any jobs being processed.
When the machine shuts down, it also performs an internal cooling down process, which enables the machine to be shut down safely. Follow the instructions below to safely shutdown the machine.
1.
Turn OFF the main power.
1. Press (Energy Saver).
2. Press [Shutdown].
If you need to immediately operate the machine after starting the shutdown process, press [Restart] → [Yes].
IMPORTANT
If the message <Backing up stored data from the Remote UI...> is displayed on the touch panel display, do not turn the main power OFF. This may cause the machine to fail to back up the stored data.
The machine may take some time to completely shutdown. Do not unplug the power cord until the main power indicator of the machine is OFF.
If the main power is turned OFF during scanning or printing, a paper jam may occur.
The machine may continue to operate during or after the shutdown process. Do not unplug the power cord until the device sounds stop.
When the shutdown process completes, the main power switch of the machine switches to the "  " side automatically.
You can also force the shutdown of the machine (omitting the normal job cancellation process) by pressing [Forced OFF]. However, since pressing [Forced OFF] stops the shutdown operation before it is complete, which may result in damaging parts of the machine, or destroying data which is being processed, it is not recommended. Note that Canon will not be liable for any damages resulting from the loss of data on the hard disk drive. For more information, contact your local authorized Canon dealer.
IMPORTANT
If the main power indicator on the control panel does not light even though the main power switch is ON, be sure to check the breaker to see if it is OFF.
If you want to turn OFF the main power and then back ON again, wait for at least 10 seconds after the main power indicator is turned OFF before turning ON the main power.
NOTE
The machine can receive and print documents from a personal computer when it is in the Sleep mode. I-fax documents can also be received while the machine is in the Sleep mode.
You can shut down the machine from the Remote UI using the Remote Shutdown mode. For more information, see "Shutting Down the Machine from the Remote UI."
