How do I adjust my Brother machine's Sleep Mode setting?

Setting the Sleep Time reduces power consumption by turning off the fuser inside the Brother machine when the machine is idle. You can choose how long the Brother machine is idle before it goes into Sleep Mode. The Sleep Mode timer is automatically reset when the Brother machine receives PC data or makes a copy. The factory setting is 05 minutes.
 

While the Brother 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 working temperature.
