Introduction

The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specific functions and the relationship between elec-

trical 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 field.

Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained

in terms of from 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."
