Chapter 22-12.1 Basic Construction2.1.1 Outline of Electric Circuit 0010-3889Electric circuits of this machine are controlled by the reader controller PCB and image processor PCB. The ASICs on the reader controller PCB and image processorPCB detect the signals received from the host machine to output the signals that drive DC loads such as motors and solenoids at the predetermined timings. Thereader controller PCB and image processor PCB do not have a memory area; data (service mode, etc.) is stored in the image processor PCB.F-2-12.2 Basic Operation2.2.1 Drive Mechanism and Signals 0010-3892This machine is a document feeder exclusively for stream reading.This machine uses two motors to pick up and feed document paper.T-2-1The drive mechanism and signals are shown below.F-2-2Name (symbol) FunctionFeed motor (M1) Feeds documents.Pickup motor (M2) Separates and feeds documents.MotorADF driver PCBReader controller PCBSolenoidSensor+24VASIC(IC2)ImageprocessorPCBJ410CN10J412CN1+3.3VJ411CN2J403 J404J308 J309PI5PI4PI8PI11PI3PI7PI62PI2PI1
