INTRODUCTION

This Service Manual provides basic facts and figures needed to service the plain paper copier NP6045 in the field. The NP6045 is designed to enable automated copying work and may be configured with the following system components:

1. Stapler Sorter-E2, Stapler Sorter-G1, Sorter-E1, Sorter-G1

2. RDF-H1

For descriptions on the system components, see their respective service manuals.

This Service Manual covers the copier only, and consists of the following chapters: Chapter 1

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 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 reasons, 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.

System Configuration

Stapler Sorter-G1 In addition to the functions of a 20-bin sorter, automatically staples sorted copies.

Sorter-G1 Is a 20-bin sorter capable of automatic sorting and grouping.

Sorter-E1 Is a 20-bin sorter capable of automatic sorting and grouping.

Stapler Sorter-E2 In addition to the functions of a 20-bin sorter, automatically staples sorted copies. Further, it swings out copies to the front for removal, and is equipped with a multiple stacking function, in which two or more sets of copies may be delivered to a single bin.

RDF-H1 Feeds originals one by one from a stack to the copyboard for copying.

CHAPTER 1 GENERAL DESCRIPTION

I. FEATURES

1. The NP6045 is capable of making as many as 45 copies (A4, horizontal) every minute.

2. It uses newly designed pick-up and feeding mechanisms so that it not only helps save space, but it also is less susceptible to jams.

3. It provides high durability and high image quality required of high-speed copying. The use of the Canon-unique A-Si (amorphous silicon) photosensitive drum ensures high durability while the single-component toner projection mechanism promises high-quality images for a long time.

4. It is equipped with a large-size liquid crystal display, offering easy-to-understand instructions.
