Sleep Time; Setting The Lcd Contrast; Security; Tx Lock (Mfc-7420 Only) - Brother MFC-7420 User Manual

Sleep Time

Setting the Sleep Time reduces power
consumption by turning off the fuser inside
the machine while it is idle. You can choose
how long the machine is idle (from 00 to 99
minutes) before it goes into sleep mode. The
timer is automatically reset when the machine
receives a Fax or PC data or makes a copy.
The factory setting is 05 minutes. While the
machine 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.
