Sleep Time
Setting the Sleep Time reduces power
consumption by turning off the fuser inside
the MFC while it is idle. You can choose how
long the MFC is idle (from 00 to 99 minutes)
before it goes into sleep mode. The timer is
automatically reset when the MFC receives a
Fax or PC data or makes a copy. The factory
setting is 05 minutes. While the MFC is in
sleep mode you will see Sleep on the LCD.
If you try to print or copy in sleep mode, there
will be a short delay while the fuser warms up
to its working temperature.
