The print module has a main power switch to turn on the print module and all optionals.
In the Settings Editor you can set timers for the energy save modes. When there is no activity during these preset periods, the system will first enter the low power mode and then the sleep mode. Then you also need to awaken the print server from sleep mode.
When enabled in the Settings Editor, the system wakes up when a job arrives in the list of scheduled jobs or when you use the control panel. (Configure sleep mode, low power mode, and shut-down mode)
In some cases the printers asks you to restart the printer, for example to enable a setting or feature.
