INTRODUCTION

This Service Manual contains the bsic facts and figures about the plain paper copier NP6218, and is compiled to serve as a handy reference for servicing the machine in the field.

The NP6218 is designed to enable fully automated copying work and may be configured with the following accessories:

1. Cassette Feeding Module-B2*

2. Cassette Feeding Module-A2*

3. Control Card IV N

4. ADF-E1

5. Staple Sorter B2/D1

6. MS-B1

7. Remote Diagnostic Device II

This manual is limited to the descriptions of the NP6218, Cassette Feeding ModuleB2/Cassette Feeding Module-A2. * May not be available in some areas but discussed in this manual.

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

Chapter 9

Maintenance and Servicing

provides tables of periodically replaced parts

and consumables/durables and scheduled servicing charts.

Chapter 10

Troubleshooting

provides tables of maintenance/inspection, standards/adjustments, and problem identification (image fault/malfunction).

Appendix contains a general timing chart and general circuit diagrams.

In addition to the above chapters, this SERVICE MANUAL contains a set of

appendixes consisting of a general timing chart and general circuit diagrams.

A separate document entitled SERVICE HANDBOOK is also available for

troubleshooting problems in the copier.

The following rules apply throughout this volume:

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 pow er switch, closing the front door, and closing the delivery unit door, which will result 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 contents of this manual may be updated from time to time to reflect improv ements rendered to the copier; a Service Information bulletin will be issued as necessary to cover major changes.

All service persons are expected to be thoroughly familiar with the information contained in this manual, SERVICE HANDBOOK, and Service Information bulletins, for quick response to the user’s needs.

System Configuration

ADF-E1

Sends originals one by one from a stack set on its tray

Stapler Sorter B2/D1, MS-B1

Automatically sorts or (page collation) or groups up to 10 sets of copies; with the sorting function, the sorted copies may automatically be stapled. (Not applicable to MS-B1.)

Control Card IV N

Allows the user to control copy volume.

Cassette Feeding Module-A2

Adds additional two cassettes.

Cassette Feeding Module-B2

Adds an additional cassette.

The NP6218 may be configured with the following systems options:

CHAPTER 1 GENERAL DESCRIPTION

I. FEATURES

The copier becomes ready to make copies as soon as it is turned on. When fitted

with options, it provides a maximum of four paper sources.

1. Multiple front loading and multifeeder for space saving.

• The cassette may be slid out to the front for paper supply work.

• With the adjustable cassette and the multifeeder, various types of paper may be used.

2. Office amenities and ecology.

• The copier is equipped with a heating mechanism, which makes the copier ready for copying work at power-on without wait time.

• The copier is designed compact, enabling effective use of office space.

• The use of roller charging has proved to reduce the generation of ozone significantly. (1/100 to 1/1000 compared to other Canon copiers)

• As the pick-up mechanism, center-reference is adopted in consideration of the use of recycled paper.

• A significant number of parts are made of plastic in an effort to promote recycling.

• The copier is designed as a clamshell type to facilitate clearing of jammed paper.

3. Dependable high image quality.

• The new HQ (high-quality) toner ensures faithful reproduction of solid black, text, and photos.

• In addition to Canon’s own single-component toner projection development method, the use of auto image control (AIC) ensures stable reproduction of images.

4. Practical basic features.

• As many as 18 copies (A4, horizontal) may be made per minute.

• Copies may be as large as A3/Ledger or as small as A5/STMT, accommodating postcards.

• The AE mechanism promises enhanced reproduction of newspapers or diazo originals.

• Using page separation mode, a book may be copied with its left and right pages processed separately.

• Copies may be made in zoom between 49% and 204%.

• The zoom fine-adjustment mechanism ensures better control for faithful reproduction of originals.

• The auto power-off mechanism helps further saving of energy.

• The interrupt mechanism enables cutting in on a continuous copying session.

CHAPTER 1 GENERAL DESCRIPTION

C. Making Two-Sided/Overlay Copies (manual)

You can make two-sided or overlay copies by manually feeding paper. You must,

however, keep the following in mind when making such copies:

q Be sure to orient the paper the same way for both sides when turning it over. w Make sure that the paper has not absorbed moisture. e Make sure that the paper has no curling. r After copying on the first side, sufficiently cool the paper; then, correct any curling

before feeding it for a second time.

t Use paper of 60 to 128 g/m y Correct any curling on postcards or thick paper (128 g/m

second side.
