INTRODUCTION

The descriptions in this Service Manual are based on he following rules:

1. In each chapter, the uses of the function in question and its relationship to electrical and mechanical systems are discussed and the timing of operation of its associated parts is explained by means of outlines and diagrams. In the diagrams, the symbol

represents a mechanical path, while the symbol

with a name next to it indicates the flow of an electric signal. The expression “turn on the power” means turning on the power switch, closing the front cover, and closing the delivery cover so that the machine will be supplied with power.

2. In circuit diagrams (digital), a signal whose level is High is expressed as being ‘1’, while a single whose level is Low is expressed as being ‘0’; the level of voltage, however, varies from circuit to circuit. The machine uses CPUs, whose internal mechanisms cannot be checked in the field, and, therefore, are not explained. In addition, the machine’s PCBs are not intended for repairs at the user’s and, therefore, are explained by means of block diagrams: two types are used, i.e., between sensors and inputs of PCBs equipped with a control or drive function and between outputs equipped with a control or drive function and loads; in addition, functional block diagrams are used at times.

Changes made to the machine for product improvement are communicated in the form of a Service Information bulletin as needed. All service persons are expected to go through all service documentation including the bulletins and be equipped to respond to the needs of the field (as by being able to identify possible causes of problems).

CHAPTER 1 GENERAL DESCRIPTION

2 Safety

2.1 Safety of Laser Light

Laser light can be harmful to the human body. The machine’s laser unit is sealed in a protective housing and external covers to prevent escape of laser light to the outside of the machine, protecting the individuals around the machine from the harmful effects of laser light as long as the machine is used in normal ways.

CHAPTER 1 GENERAL DESCRIPTION

2.2 CDRH Ordinance

The Center for Devices and Radiological Health of the US Food and Drug Administration

put into effect an ordinance to govern laser products on August 2, 1976.

The ordinance applied to laser products produced on August 1, 1976, and the sale of laser

products is banned in the US without certification under the ordinance.

The following is the label indicating compliance under the CDRH ordinance, and it must

be attached to all laser products sold in the US.

F01-202-01

A different description may be used for a different product.

CHAPTER 1 GENERAL DESCRIPTION

2.3 Handling Parts Associated with the Laser Unit

Do not introduce a screwdriver or the like (i.e., with a high degree of reflectance) into the laser path when servicing the areas around the laser unit.

Also, remove watches, rings, and the like to prevent laser light from reflecting to your eyes.

Extra attention is called for when servicing the inside of covers to which the following label is attached.

The machine is equipped with a shutter to cut off the path of laser light. The shutter operates in conjunction with the hopper assembly, and remains open as long as the hopper is set in the machine, closing when the hopper assembly is slid to the front.

It is even more important to heed the foregoing points when the hopper assembly is inside the machine or when a shutter opening tool is fitted (after sliding out the hopper assembly).
