Theory of Operation
Energy Saver Mode (Deep Sleep)
To save power consumption, the printer enters Energy Saver mode when it has not
received print data for a certain time after it has entered the Standby mode. The
default waiting time before switching to Energy Saver mode is 1 minute. It can be
set in increments of 1 minute in the range between 1 and 240 minutes from the
Control Panel. The printer cannot be prohibited from entering this mode.
This is not guaranteed when a non-standard HDD etc. is installed as an option.
Recovery from Energy Saver Mode
The printer returns to Ready mode when a print job is received or the Energy Saver
button on the Control Panel is pressed during Energy Saver mode.

The status transition among the operating modes is illustrated as in the illustration
