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 field. Theref ore, 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 improvem ent or other purpo ses, and maj or 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."

The delivery accessories for the machine can be divided into three patterns in accordance with the available functions.

- In case a large amount of delivery processing or a several types of delivery processing (e.g., staple, punch) are necessary: system configuration 1 for the delivery
accessories.

- In case some delivery processing (e.g., staple) is necessary: system configuration 2 for the delivery accessories.

- In case some delivery processing (e.g., three-system sorting) is necessary: system configuration 3 for the delivery accessories.
