Adjust the Brother machine's Sleep Time setting
The Sleep Mode Setting can reduce power consumption. When the machine is in Sleep Mode (Power Save mode) it acts as though it were turned off. Receiving data or starting an operation wakes up the machine from Sleep mode to Ready mode.
You can choose how long the machine must be idle before it goes into sleep mode. When the machine receives a fax (if applicable), computer data or makes a copy, the timer will be reset.
While the machine is in sleep mode the LCD will show Sleep .
