2006 Fuji Xerox DocuCentre-II C3000 Copier Service Manual, Draft2 Edition (P/N SM-TC100179-0-01-0)

Fuji Xerox service manual for the DocuCentre-II C3000 digital copier, Draft2 Edition, issued July 2006, Material No. SM-TC100179-0-01-0. It covers field service for the main unit and the documented paper-handling, finishing, and fax options.

• Fault isolation: Status-code Repair Analysis Procedures (RAPs), power-on diagnosis, paper-jam troubleshooting, and image-quality analysis with defect samples and test patterns.

• Imaging and development: ROS replacement, developer housing and material replacement, print drum service, IBT module and belt replacement, and second BTR contact-arm service.

• Scanner and DADF: IIT/IPS PWB replacement, CCD optical-axis alignment, IIT calibration, carriage adjustment, and document-feeder registration, height, and skew adjustments.

• Paper handling: MSI feeder service, feed/nudger/retard roll replacement, registration-unit removal, and separate procedures for Two Tray and Tandem Tray Modules.

• Control electronics: MCU and ESS PWB replacement, NVM read/write, HFSI counter management, component-control diagnostics, HDD testing, and firmware loading and upgrading.

• Finishing and fax: Finisher-B and Finisher-A transport, stapler, and stacker repairs, plus installation procedures for Fax Kit A and Fax Kit B.

• Electrical reference: Functional-chain wiring diagrams, Block Schematic Diagrams (BSD), wire nets, plug/jack location views, and illustrated replacement-parts lists.

This manual was written for maintenance service personnel authorized by Fuji Xerox.

Status Codes and Image Quality

Service-call procedures connect reported symptoms with jam, failure, and shutdown histories. The TRIM checklist and periodical-replacement tables cover cleaning tasks, replacement intervals, and counter references for wear items.

Separate IIT and IOT entry RAPs help distinguish a scanner-side defect that appears only on copies from an output-side fault that also affects prints.

Image-quality diagnosis covers color misregistration, ghosting, low density, missing colors, and repeating bands or spots. The defect samples and test-pattern references support comparison with the machine's actual output.

The 010-320 Heat Roll Over Temperature RAP includes fault-specific handling of NVM location 744-004 after repair, alongside fuser and circuit checks.

Component Replacement and Alignment

The disassembly chapter pairs removal and replacement illustrations with REP and PL references. Developer service extends to replacing the material inside the housing and updating its HFSI counter; IBT coverage includes the cleaner, belt, and module.

Scanner adjustments distinguish CCD-to-lens optical-axis alignment from IOT image registration. Optical-axis alignment is specified after lens or CCD replacement, or when directed by the service documentation.

Two Tray and Tandem Tray Modules have separate feeder and control-board procedures. Finisher coverage reaches the staple assemblies, transport belts, stacker drives, and Finisher-A tamper mechanisms. The accessory chapter distinguishes Fax Kit A (EC100738) from Fax Kit B (EC100739).

Control Boards and Customer Data

The board-replacement sections warn that replacing the ESS and MCU PWBs with their EPROMs at the same time can disable the machine through loss of serialization and billing data. They also identify EPROM pin breakage as a risk during careless removal or installation.

Save-and-restore procedures address service, factory, and customer settings. The service-call precautions explain handling of customer information stored on PWBs and HDDs, while the general section provides NVM tables, component-control tests, and software-upgrade procedures.

The service precautions address electrical isolation, moving drive components, and protection of static-sensitive electronics.

Wiring, Connector Locations, and Parts

Diagram coverage includes Laser Control and Scanning, Development and Toner Dispense Control, Fusing Heat Control, and Finisher-A DC Power and Interlock Switching. Wire Net DC COM (+5VRTN)-3 and the plug/jack views provide connector and circuit-location references.

Exploded parts-list plates identify replacement part numbers and cross-reference the related repair and adjustment sections.

A Preview of Fuser Checks and Image Registration

These examples are a small selection of the manual's electrical test and alignment data. The 010-311 fuser RAP specifies control and rear thermistor resistance of 3 kΩ or higher, rather than a fixed 3 kΩ reading.

For A3 paper, the IOT image-registration section gives lead-edge registration of 10.0 ± 0.5 mm and side-edge registration of 8.0 ± 0.5 mm on both sides.

Text Search, Diagram Detail, and PDF Contents

Search and diagram access: Service text is searchable; text inside wiring-diagram images is not. There are no embedded PDF bookmarks, and small connector, pin, and wire-code labels require zooming.

The download is one printable, English-language 1,030-page PDF. That total includes 1,004 numbered chapter pages, 10 opening pages, and 16 chapter-divider and blank reverse pages; these are all part of the same service manual.
