Symbols Used

This documentation uses the following symbols to indicate special information:

Symbol Description

Indicates an item of a non-specific nature, possibly classified as Note, Caution, or Warning.

Indicates an item requiring care to avoid electric shocks.

Indicates an item requiring care to avoid combustion (fire).

Indicates an item prohibiting disassembly to avoid electric shocks or problems.

Introduction

Memo

REF.

Indicates an item requiring disconnection of the power plug from the electric outlet.

Provides a description of a service mode.

Provides a description of the nature of an error indication.

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. 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."

Chapter 2

2.2.1 Delivery to the No. 1 Delivery Slot

0001-1087

The machine delivers paper to its No. 1 delivery slot as follows:

1) Paper arrives from the host machine. A specific period of time after the leading edge of the paper reaches the fixing

outlet sensor (PS13), the No. 1 delivery solenoid (SL1) goes on to prompt delivery to the No. 1 delivery tray.

The machine delivers paper to its No. 2 delivery slot as follows:

1) Paper arrives from the host machine. A specific period of time after the leading edge of the paper reaches the fixing

outlet sensor (PS13), the No. 2 delivery motor (M1) starts to rotate; then, the paper moves past the No. 2 delivery

sensor (PS1A) and the No. 2 delivery tray full sensor (PS2A) to reach the No. 2 delivery tray.

The machine delivers paper to the No. 3 delivery slot as follows:

1) Paper arrives from the host machine. A specific period of time after the leading edge of the paper reaches the fixing

outlet sensor (PS13), the No. 2 delivery motor (M1) and the No. 3 delivery motor (M2) start to rotate.

2) When the paper has moved past the reversal sensor (PS4A) and its trailing edge reaches a specific point in relation

to the reversing roller, the No. 3 delivery motor (M2) stops once; thereafter, it starts to rotate in reverse after a

specific period of time. At the same time, the No. 3 delivery motor (M2) goes on, and the paper moves past the

No. 3 delivery sensor (PS5A) to reach the No. 3 delivery slot.

The machine moves paper as follows when making a double-sided copy (print):

1) Paper arrives from the host machine. A specific period of time after the leading edge of the paper reaches the fixing

outlet sensor (PS13), the No. 2 delivery motor (M1) and the No. 3 delivery motor (M2) start to rotate.
