Introduction

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.

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

Indicates an item intended to provide notes assisting the understanding of the topic in question.

Memo

Indicates an item of reference assisting the understanding of the topic in question.

REF.

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.»

1.2.5 Safety

1.2.5.1 Safety of the Laser Light

Laser light can prove to be hazardous to the human body. The machine’s laser unit is fully enclosed in a protective housing and external covers so that its light will not escape outside as long as the machine is used normally.

1.2.5.2 CDRH Regulations

The Center for Devices and Radiological Health of the US Food and Drum Administration put into force regulations concerning laser products on August 2, 1976. These regulations apply to laser products manufactured on and after August 1, 1976, and the sale of laser products not certified under the regulations is banned within the Untied States. The label shown here indicates compliance with the CDRH regulations, and its attachment is required on all laser products that are sold in the United States.

1.2.5.3 Handling the Laser Unit

1-19

Chapter 1

The laser scanner unit emits invisible laser light inside it. If exposed to laser light, the human eye can irreparably be damaged. Never attempt to disassemble the laser scanner unit. (It is not designed for servicing in the field.)

Warning labels are affixed to the top cover of the laser scanner unit and the inner cover inside the front cover of this machine.

1.2.5.4 Safety of Toner

The machine’s toner is a non-toxic material made of plastic, iron, and small amounts of dye.

Do not throw toner into fire. It may cause explosion.

Toner on Clothing or Skin

1.If your clothing or skin has come into contact with toner, wipe it off with tissue; then, wash it off with water.

2.Do not use warm water, which will cause the toner to jell and fuse permanently with the fibers of the cloth.

3.Do not bring toner into contact with plastic material. It tends to react easily.

1.2.5.5 Point to Note about Fire

It is dangerous to throw lithium batteries and parts and components containing flammable substances, such as cartridges, etc., into fire. Such parts and components must be disposed of in accordance with local laws and regulations.
