Chapter 33-23.1.2 Functional Block Diagram 0006-2838F-3-23.1.3 Image Processor PCB 0006-4284It controls the machine as a whole, and communicates directly with all PCBs except the sensor PCB and modularjack PCB.Drive Control BlockThe drive control mechanism acts on the reader motor and the ADF motor by the work of the ASIC and motor driveIC.Control Panel Control BlockThe control panel control block receives the state of control keys while sending/receiving data in serialcommunication with the control IC of the control panel PCB. Also, it sends LED and LCD signals to the control panelMemb-rane LCD Speaker *2J7 *3 /J8 *3 /J10 *4Telephone lineTo power supplyTransmissionModularJackPCB*2DeliverysensorNCU PCB*2Fixing assemblyPower supply PCBSwitchingregulatorCartridgeDC controller PCBFixing heater control blockHigh-voltage control blockDrive control blockSensor detectionImage processor PCBinterface blockLaser control blockHorizontal sync signal controlScanner motor controlCartridge detection mechanismToner level detectionmechanismKey detectionand LCD/LEDdriveLCDfunctionSerialcommunicationcontrolControl panelPCB 2-Line/4-Lineconversion circuitDial pulsegenerationcircuitLine voltageconversion circuitOff-hookdetectioncircuitImage processor PCBDrive control blockControl panel control blockImage processing control blockSensor detectionMemory functionESS controlCommunication control blockSpeaker control *2J403J4030 J4020J402J401 J1/J2/J6 J103/104 J204/201J315 J81 *2 /J320 *2 /J321 *3 J301/302 J303/304J404AnalogprocessorPCBContactsensorSensor PCBReader motorADF*1Laser scannermotor driverScannermotorFanManual feed pickupsolenoidManual feed traypaper sensorCassette pickupsolenoidLaser driver/BD PCBOriginalsensorRegistrationsensorADF motorJ317J501J503J504J502J601J310J3102J311 *1J3112J3113J3114J3110J316J801 J3120 J3124 J3081J312 J309 J307 J314 J308CommunicationControlUSB serialnumber noticefunctionSmoothingPrinter ControllerPCBParallel I/FUSB I/FJ701J318J109J7 J206 J252 J251J2521J651J202/J203J106/J108J205/J207/208/J209J105/J107/J907 *4 /J911 *3 /J912 *3ReceptionJ1051PS3PS102PS10PS103PS11J652J6521PCPS4Contact sensorhome positionsensorPS1ADF(copyboard cover)open/closesensorPS2PS6PS7OriginaldeliverysensorPS8SL2SL1FM1M4M3M2Main motordriverMainmotorJ3123M1Cassettepaper sensorPaper leadingedge sensorPS101LGL papersensorJ4 J102 *2Reader unit slidedetecting switch*1 : If equipped with ADF functions.*2 : If equipped with fax functions.*3 : If equipped with fax functions and 230V model.*4 : If equipped with fax functions and 120V model.SW1SW2Sensor relayPCBJ653J6531HSToner bottlesensor Humidity sensorWaste tonerfull sensorWaste toner fulldetection functionToner supply coveropen / close switch
