Symbols Used

This documentation uses the following symbols to indicate special information:

Symbol Description

Indicates an item of a non-specific nature, possibly classified as Note, Caution, or Warning.

Indicates an item requiring care to avoid electric shocks.

Indicates an item requiring care to avoid combustion (fire).

Indicates an item prohibiting disassembly to avoid electric shocks or problems.

Indicates an item requiring disconnection of the power plug from the electric outlet.

Indicates an item intended to provide notes assisting the understanding of the topic in question.

Memo

Introduction

REF.

Indicates an item of reference assisting the understanding of the topic in question.

Provides a description of a service mode.

Provides a description of the nature of an error indication.

Introduction

The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with refer­ence to the timing of operation.

In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol , the arrow indicates the
direction of the electric signal.
The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in
supplying the machine with power.

2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".(The voltage value, how­ever, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the fi eld. Ther efore, the operations of the microprocessors
used in the machines are not discussed: they are explained in terms of fro m sensors to the input of the DC controller PCB and from the output of the
DC controller PCB to the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be com­municated in the form of Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be
able to identify and isolate faults in the machine."
