The printer needs a warm drum to print and this consumes a lot of electrical power. If the printer is idle for a long time, it can save a lot of electrical power by switching off the drum's heater. This happens by the cost of more time is required to warm up again the next time the printer should print.

Note: If power_save_time isn't set, power saving defaults to 5 minutes
