3 Control at Time of Energy Save Mode
3.1 Outline
The machine is equipped with energy save mode (hereafter, ESS) used to save on power
the machine consumes in standby state.
The machine turns on the ESS mechanism for the following:
[1] When the machine has remained in standby for a specific period of time*.
• As determined in user mode. (standby time: 3 to 30 min; 15 min factory default)
[2] When the Energy Save key in the control penal is pressed.
3.2 Control
The ESS mechanism is controlled by the image processor PCB, and is controlled as fol-
lows (for ESS1/ESS2 control, see 2.2.4 in Chapter 7):
[1] When the machine has remained in standby state for a specific period of time,
If the machine has remained in standby state for a specific period of time at the end of
which the ESS mechanism is set to go ON (as set in user mode), the ASIC on the image
processor PCB generates the ESS control signal, which is used to cut off the supply volt-
age sent to the remote ON/OFF system.
In ESS1 control, however, 24VR2 to the DC controller PCB is retained for control of the
fixing heater.
[2] When the Energy Save key in the control panel is pressed,
If the Energy Save key on the control panel is pressed, the ESS input signal will be sent
to the ASIC on the image processor PCB.
Based on the control signal, the ASIC sends the ESS control signal, which in return will
be used to cut off the supply voltage to the remote ON/OFF control system.
In ESS1 control, however, 24VR2 to the DC controller PCB is retained for control of the
fixing heater.
Memo
Power Consumption in Standby
Normal standby : about 30 W
ESS1 control : about 20 W
ESS2 control : about 4.8 W
