Auto Power-Off
Auto Power-Off is automatically enabled by default when you turn on the printer. When Auto Power-Off is
enabled, the printer automatically turns off after 2 hours of inactivity to help reduce energy use. Auto Power-Off is
automatically disabled when the printer establishes a wireless or Ethernet (if supported) network connection. You
can change the Auto Power-Off setting from the control panel. Once you change the setting, the printer maintains
the setting. Auto Power-Off turns the printer off completely, so you must use the power button to turn the
printer back on.
To change Auto Power-Off setting
1. From the Control Panel home screen, which displays Copy, Scan, and Quick Forms, select Settings.
NOTE: If you do not see the home screen, press the Back button until you can see it.
2. From the Settings menu on the printer display, select Preferences.
3. From the Preferences menu, select Auto-Off.
4. From the Auto-Off menu, select On or Off, and then press Continue to confirm the setting.
TIP: If you are printing over a wireless or Ethernet connected network, Auto Power-Off should be disabled to
ensure that print jobs do not get lost. Even when Auto Power-Off is disabled, the printer enters Sleep mode
after 5 minutes of inactivity to help reduce energy use.
