CHAPTER 8 EXTERNALS AND AUXILIARY CONTROL SYSTEMCOPYRIGHT © 2002 CANON INC. 2000 CANON iR1600/iR2000/iR1610/iR2010 SERIES REV.0 MAR. 20028-63 Control at Time of Energy Save Mode3.1 OutlineThe machine is equipped with energy save mode (hereafter, ESS) used to save on powerthe 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 ControlThe 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 ofwhich the ESS mechanism is set to go ON (as set in user mode), the ASIC on the imageprocessor 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 thefixing 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 sentto the ASIC on the image processor PCB.Based on the control signal, the ASIC sends the ESS control signal, which in return willbe 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 thefixing heater.MemoPower Consumption in StandbyNormal standby : about 30 WESS1 control : about 20 WESS2 control : about 4.8 W
