INTRODUCTION

The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specific functions and the re-

lationship 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 sig-

nal.

The expression “turn on the power” means flipping on the power switch, closing the

front cover, and closing the delivery unit cover, 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 ma-

chines 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 Ser-

vice Manual and all relevant Service Information bulletins and be able to identify and isolate

faults in the machine.

Important!

Be sure to turn off the main power switch and disconnect the power plug before starting

to disassemble the machine; in addition, keep the following in mind for the work:

1. In printer mode, turning off the main power switch can result in the loss of data being

processed. Check to make sure that the Execution/Memory lamp on the control panel

is off before operating the main power switch.

2. Do not turn off the main power switch while downloading is taking place. Otherwise,

the machine may become disabled.

3. The cassette heater and the drum heater remain powered as long as the environment

switch and the heater switch are on (even when the main power switch is off).

4. Not all power is removed when the front cover is opened if the main power switch is

on, requiring care.
