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
signal shows the mechanical drive transmission.
When the
signal is shown with a signal name, it indicates the electric signal
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.
