Generally, we all know that when the printing machine is in sleep mode then it can reduce the power consumption. And machine acts as it is OFF.
You can also select for how much time the device should be idle before it goes into Sleep mode. When the printer accepts a system data or makes a copy, then at that situation timer will be reset.
Select Sleep Time under Printer Function. After performing, steps carefully select the setting to set for Sleep time option.
This is the most appropriate setting which automatically adjusts printer for the most suitable timeout.
It turns the machine into the Sleep mode for the specific time which is set by a user.
This setting turns the device into the Sleep mode when the exact time set at the factory passes without getting data after the machine prints the last job.
