Set the auto-off feature
The printer is designed with an auto-off feature that automatically places the printer into
a low power mode when it has been idle for 30 minutes. In this mode, the printer continues
to consume a maximum 3.0 watts of power and turns back on automatically when print
jobs are sent to the printer. You can manually turn the printer off by pressing and holding
the
Power button for three seconds. When the printer is manually turned off, the printer
uses less than one watt of power. Manually powering off the printer is recommended if
the printer causes interference with other wireless devices, or if you do not plan to use
the printer for a long period of time.
Selecting auto-off cancels the
FEMP energy savings mode.
Energy consumption can be prevented by turning the printer power off, and then
disconnecting the end of the printer power cord from the electrical source.
Follow these steps to activate the auto-off feature:
1.
Open the printer Toolbox .
2. Click the Configuration tab.
3. Select Activate the Hardware Auto-off feature.
4. Click Apply, and then click OK.
