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 working temperature.

If the MFC is in Sleep Mode when you change the Sleep

lamp’s life. Some people prefer to turn the lamp off as they leave
the office, or late at night at home. This is not necessary for
normal day to day use.
