When the sleep mode is set to on and the printer does not receive data for a certain period of time, it enters sleep mode and acts as though it were turned off. During that time, the back light is off and the LCD shows "Sleep", but the printer can still receive data and start printing if it receives a print file or document or pressing the Go button. If the printer does not start printing when receiving data, press the Go button to print it.
 

You can change the sleep mode setting from the control panel of the printer or the printer driver.

From the control panel of the printer:

1. Make sure that the front cover is closed and the power cord is plugged in.
2. Turn on the printer and wait until the printer is in the Ready state.
3. Press any of the Menu buttons (+, -, OK or Back) to take the printer off line.
4. Press + or - to choose "General Setup". Press OK.
5. Press + or - to choose "Ecology". Press OK.
6. Press + or - to choose "Sleep Time". Press OK.
7. Choose the time that you are going to make the printer enter sleep mode. E.g. 1, 2, 3, 4, 5...
8. Press OK or Go.
   The printer will enter sleep mode when the time you have set passes without receiving data after the last job is printed.
