How do I adjust the sleep timer on printer (FX M455DF)?

• Click the info icon
• Click tools
• Admin
• System
• General
• Energy Saver - then adjust both power and sleep timer.

Warning: the purpose of the sleep timer is to increase the life expectancy of the on-board computer and LCD screen. By increasing the time it takes to turn off, will result in longer up time, meaning more use of the computer/SCREEN therefore decreasing its life expectancy.
