    INTRODUCTION

    2 Outline of the Sevice ManualThis Service Manual contains basic information needed to service the DADF-D1in the

    field, conducted for the purpose of maintaining its product quality and a specific level ofperformance.

    This Service Manual consists of the following chapters:

    Chapter 1 General Description, shows the features and specifications of the machine,as well as the names of parts and how to operate it.

    Chapter 2 Operations and Timing, explains the mechanical and electrical systems ofthe machine by function in relation to the principles of operation and timingat which they are driven.

    Chapter 3 Mechanical Systems, shows how to disassemble/assemble the machineand make adjustments.

    Chapter 4 Maintenance and Inspection, provides tables of periodically replacedparts and consumables/durables and a scheduled servicing chart.

    Chapter 5 Troubleshooting, contains troubleshooting tables and diagrams of electricalparts, lists of VRs, LEDs, and check pins by PCB, and an outline of self-diagnosis.In addition, an appendix is added to offer a general timing chart, list of sig-nals/abbreviations, general circuit diagrams, and PCB diagrams.

    INTRODUCTION

    The following rules apply throughout this document:As a rule, the descriptions in this documentation are based on the following:1. As needed, the work of each function and its relationship with electrical and me-

    chanical parts are explained; where applicable, the timing at which associated partsare driven are also outlined.In a diagram, the symbol indicates a path of mechanical drive; the symbol

    accompanied by a notation indicates the flow of an electrical signal.The expression power-on means turning on the power switch, closing the frontdoor, and closing the delivery door so that the parts of the machine are supplied withpower.

    2. In a digital circuit, the state of a signal is indicated by 1 if its voltage level is highand by 0 if low. The level of voltage, however, differs from circuit to circuit.The machine uses a CPU; however, since the internal functions of a CPU is outsidethe scope of a service person, detailed explanations are omitted from descriptions. Inthis document, a circuit diagram may cover from sensors to inputs of a controllerPCB or from outputs of a controller PCB to loads, or it may be a functional diagram.

    The descriptions of the machine are subject to change for product improvement, and ma-jor changes will be communicated in the form of Service Information bulletins.

    All service persons are expected to be fully familiar with the contents of this ServiceManual and Service Information bulletins to develop a good understanding of the machine,equipping themselves with the ability and skill to identify faults and to maintain the machinein good order.
