2. Basic Sequence of Operations at Power-On (2/2)The following sequence applies when the surface temperature of the fixing roller is75°C at power-on and, in addition, the ambient temperature is 17°C or more.Figure 2-104Charging wire cleaningmotorINTRPower ONPre-transfer chargingassembly DCPre-transfer chargingassembly ACTransfer chargingassemblySeparation chargingassembly DCSeparation chargingassembly ACPre-exposure LEDBlank exposure LEDFixing main heater (H1)Fixing sub heater (H2)Main motor (M1)Primary charging assemblyDeveloping bias DCDeveloping bias ACSurface potential controlScanning lamp (LA1)......VD VL1 VL2WMUP195 C(200 C)CNTR1 CNTR2 LSTR STBY200 C(205 C)WMUPRControlled to200 C (210 C)The difference from the basic sequence of operations (1/2) is that WMUPR is executed until the surface temperature ofthe fixing roller reaches 200 C (210 C) by not ending LSTR in 10 sec after the end of potential control (CNTR1,CNTR2).The value within parentheses applies when the ambient temperature is 17 C or less and, in addition, the surfacetemperature of the fixing roller at power-on is 75 C or less.The value outside the parentheses applies when the surface temperature is 75 C or more.COPYRIGHT © 1997 CANON INC.
