Power States of this Machine

	State	Description
1	Standby/Printing	State where normal operation is possible after warm-up State during printing
2	Printing state/Panel OFF	State when printing with the backlight of the operation panel turned off
3	Fusing OFF	State where the Standby Fusing OFF state is entered when the time set with the "Fusing Unit Off Mode (Energy Saving) On/Off" setting of the Settings has elapsed. State where the operation panel is flashing and the fusing lamp is OFF. The bottom plate of the paper feed tray is raised.
4	Quiet state	Quiet state is entered when the Energy Saving key is pressed or the time set with the "Sleep Mode Timer" of the Settings has elapsed. This is a temporary energy saving state before entering sleep mode. Basically, no homing (initialization) of peripheral devices is performed. The bottom plate of the paper feed tray is raised. The fusing lamp is turned OFF.
5	Engine OFF (Sleep mode)	Entered from Quiet state with the internal timer. The relevant power systems (24V, 12V, 5V) are turned OFF at the same time as the fusing lamp. When receiving a fax or printing is performed in engine OFF state, the warm-up is started and printing is performed while the backlight of the operation panel is turned OFF.
6	STR state (Sleep mode)	Supplying of power and clock to the CPU and peripheral chips on the controller board is stopped.
7	Pre-recovery	The Pre-recovery state is entered from STR state when the Proximity Sensor (S49) detects the presence of a person. This is the Energy Saving state where the power of the operation panel and HDD is ON and the power of the engine is OFF, but the backlight of the operation panel LCD is off.

Device state for each Energy Saving state

State	Energy Saving LED	Operation panel LCD	Engine (Printer/Scanner)	HDD	CTL
Standby/Printing	ON	ON	ON	ON	ON
Printing state/Panel OFF	ON	OFF	ON (Only scanner is in Quiet state)	ON	ON
fusing OFF	ON	ON	ON (Both printer/scanner are in Quiet state)	ON	ON
Quiet state	ON	OFF *ON1**	ON (Both printer/scanner are in Quiet state)	ON	ON
Engine OFF	Blinking gradually *ON1**	Sleep *OFF or ON1**	OFF	OFF *ON1**	ON
STR state	Blinking gradually	Sleep	OFF	OFF	STR
Pre-recovery	ON	OFF *ON1**	OFF	ON	ON

*1 When [Energy Saving Recvry. for Business Application.] is [On (Energy Saving)], ON/OFF is determined by the internal timer of the Smart Operation Panel.

The transition of the operation panel to Energy Saving when [Energy Saving Recov. for Business Application] is [On (Energy Saving)]

Normally, the Energy Saving state of the operation panel LCD changes in step with the energy saving state of the MFP/LP main machine, but to support the scenario where an application that does not use the engine (printer/scanner) is executed from the operation panel, the Energy Saving state of the operation panel is transitioned through the three states ON, OFF, and Sleep with its internal timer when [Energy Saving Recov. for Business Application.] is [On (Energy Saving)].
