INTRODUCTION

This Service Manual provides the basic facts and figures about the plain paper

copier NP6330 needed for servicing it in the field.

The NP6330 is designed to enable full automation of copying work, and may be

configured with various accessories.

(For detailed descriptions of sorters, ADFs, RDFs, and controllers, see their

respective Service Manuals.)

This Service Manual covers the NP6330 and the pedestal, and is organized as

follows:

Chapter 1

Chapter 9

Installation

introduces requirements for the site of installation, and

shows how the copier may be installed using step-by-step instructions.

Chapter 10

Maintenance and Inspection

provides tables of periodically replaced

parts and consumables/durables and scheduled servicing charts.

Chapter 11

Troubleshooting

provides tables of maintenance/inspection,

standards/adjustments, and problem identification (image fault/malfunction).

Appendix contains a general timing chart and general circuit diagrams.

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 door, which results in supplying the copier 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 copiers 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 copier.

System Configuration

The NP6330 may be configured with the following accessory:

iii

Stapler Sorter-D2/MS-B1

Automatically sorts (page collation) and groups up to 10 sets of copies. In addition to sorter functions, is equipped with stapler sorter functions which automatically staple sorted copies. (Not applicable to MS-B1.)

ADF-E1

Feeds a stack of originals one by one to the copyboard for copying.

RDF-F1

Feeds a stack of originals one by one to the copyboard for copying. In addition, automatically turns over each two-sided original.

Paper Deck Pedestal-M1 (1 paper deck)

Adds 1500 sheets of paper.

Sorter-E1

Automatically sorts (page collation) and groups up to 20 sets of copies.
