Sleep and Auto Sleep
To enter Sleep, press the Power key. Touch panel and all indicators on the operation panel will
go out to save a maximum amount of power except the Main Power indicator. This status is
referred to as Sleep.
If print data is received during Sleep, the touch panel lights up and printing starts.
When using the optional fax, received data is printed out while the operation panel remains
unlit.
To resume, press the Power key. The machine will be ready to use within 23 seconds.
Note that ambient environmental conditions, such as ventilation, may cause the machine to
respond more slowly.
Auto Sleep
Auto Sleep automatically switches the machine into Sleep if left idle for a preset time in the
Low Power Mode. The default preset time is 20 minutes (for the 20 ppm model) and 30
minutes (for the 25 ppm model).
For more information about configuring settings, refer to Sleep Timer on page 9-24.
Energy Saver
This mode reduces power consumption even more than normal Sleep mode, and allows Sleep
Mode to be set separately for each function. Printing from a computer connected with a USB
cable is not available while the machine is asleep.
To use the machine, press the Power key. The time required for the machine to wake up from
power save mode and resume normal operation will be longer than for normal Sleep Mode.
For more information on Energy Saver Mode settings, refer to Sleep Level on page 9-24.
NOTE
If the optional Gigabit Ethernet Board is installed, Energy Saver cannot be specified.
