Power-saving Function
The power supply mode of this equipment is divided into "Standby" mode and "Sleep" mode.
Further, "Sleep" mode is divided into the followings: "Sleep Standby", "Deep Sleep", and "Sleep 1".
* The time specified in Settings/Registration> Preferences> Timer/Energy Settings> Auto Sleep Time. By default, it takes a minute after completion of printing, scanning or fax job.
Standby Mode
The state that the machine is running or can start operation immediately and all the power is supplied in this mode.
When turning OFF the Control Panel Power Switch or the specified period of time has passed, the mode is shifted to Sleep mode.
When turning ON the Control Panel Power Switch while in Sleep Standby mode, the mode is shifted to this mode.
Sleep Standby Mode
The state that only the Control Panel is off while the power is supplied to all other parts.
In the case of shifting to Sleep mode from Standby mode, the machine goes through this mode. Presence of a job is determined and if there is no job, the mode is shifted to Deep Sleep/Sleep 1 mode.
When a job is submitted during sleep (Deep Sleep/Sleep 1 mode), the mode is shifted to this mode.
Deep Sleep Mode
The state that the Control Panel is off while only all-night power (3.3 V) is supplied.
When "Low" (default) is set in Settings/Registration> Preferences> Timer/Energy Settings> Sleep Mode Energy Use, the mode is shifted from Sleep Standby mode at sleep state.
However, when the host PC is connected to the USB device interface, it is not shifted to Sleep 1 mode even if "Low" is set.
The mode is shifted to Sleep Standby mode when a job is submitted during this mode, and is shifted to Standby mode when the Control Panel Power Switch is pressed.
Sleep 1 Mode
The state that the power is not supplied to the printer and scanner but all-night/non-all-night power is supplied to the controller while the Control Panel is off.
When "High" is set in Settings/Registration> Preferences> Timer/Energy Settings> Sleep Mode Energy Use, the mode is shifted from Sleep Standby mode at sleep state.
The mode is shifted to Sleep Standby mode when a job is submitted during this mode, and is shifted to Standby mode when the Control Panel Power Switch is pressed.
When "0" (default) is set in COPIER> OPTION> USER> SLEEP1SW, power supply to a printer or scanner is stopped at this mode; thus, it takes time for recovery after job reception. When "1" is set, power is supplied during sleep so that the machine recovers faster.
