Turning On/Off the Main Power

CAUTION

  • When disconnecting the power cord from the wall outlet, always pull the plug, not the cord. Pulling the cord can damage the power cord. Use of damaged power cords could result in fire or electric shock.

Important

  • Do not turn off the power while the machine is in operation.

  • Do not hold down the main power switch while turning off the main power. Doing so forcibly turns off the machine's power and may damage the hard disk or memory and cause malfunctions.

  • If a power outage is planned for your work environment, such as turning off the power of your building to do maintenance, turn off the main power in advance. If the power outage occurs while the main power is turned on, it may cause a malfunction.

Turning off the main power

1Push the main power switch.

The main power indicator goes out. The main power turns off automatically when the machine shuts down. If the screen on the control panel does not disappear, contact your service representative.

Note

  • After you switch the main power on, a screen may appear to indicate that the machine is initializing. Do not switch the power off during this process. Initialization takes about 2 minutes.
