Chapter 12, "Maintenance and Inspection," : Table of periodic replacement parts and

consumables replacement targets, periodic service list and parts to be cleaned during a

customer service call.

Chapter 13, "Troubleshooting," : Standards / adjustments, operation failure counter-

measures and delivery failure countermeasures

Appendix : General timing chart, general circuit diagram, etc..

The explanations in this manual are based on the following principles.

1. Each chapter gives an overview of each function's purpose, role and the connection

between the electrical and mechanical systems as well as the operation timing of

each part.

In the outline diagram, the

flow.

In the explanation of this units digital circuit, "1" is indicated when the signal's volt-

age level is high, and "0" is indicated when it is low. However, the voltage value will

differ depending on the electrical circuit. Furthermore, the * in the signal value

[DRMD*] shows the DRMD signal is "0" and ON.

In each chapter, [Power supply ON] indicates the power supply SW has been turned

"ON", the front door, etc., has been shut, and power is being supplied to the copier.

2. This unit utilizes micro processors, however, due to the impossibility of checking the

micro processor's internal operation, an explanation of the micro processor's opera-

tion has been omitted. Furthermore, assuming that internal repair of the print circuit

board will not take place on the customer's premises, the explanation of the circuit in

the print circuit board's circuit is limited to an outline explanation using a block dia-

gram. Consequently, the electrical circuit explanations consist of 2 types, from the

sensors to the main circuit board's input section, and from the main circuit board's

output section to the load, and block diagrams by function.

Changes of the contents made for the sake of product improvements will be notified

in Service Information (Technical Information).

Gaining a sound and thorough understanding of the copier through careful reading

of this service manual and the subsequently issued Service Information (Technical

Information) bulletins is the only way to develop the technical skill necessary to prolong

product quality and functionality and the practical ability to be able to determine the

cause of breakdowns.
