2000 Canon C2050/C2020/iR C2100/C2100S Service Handbook & Parts Catalog Manual Set (P/N FY8-23B9-000)

This technical reference combines Canon's Service Handbook, P/N FY8-23B9-000, Revision 0, with the Parts Catalog, P/N FY8-31ER-000, Revision 0-01, for the 2000 Color imageRUNNER C2050/C2020 and iR C2100/C2100S.

• Reader service: Scanner drive cable routing, scanning lamp adjustment, CCD replacement settings, and reader controller PCB replacement procedures.

• Printer and duplex feed: Image registration, manual feed tray timing belt installation, paper-width adjustment, and duplex sensor checks.

• Fixing unit: Web replacement follow-up, fixing roller replacement settings, nip width checks, and skew correction.

• Electrical diagnosis: Photointerrupter voltage and state tables, PCB check points, connector references, wiring diagrams, and system timing charts.

• Service modes and fault codes: DISPLAY, I/O, ADJUST, FUNCTION, OPTION, TEST, and COUNTER references, plus copier and accessory self-diagnosis tables.

• Controller updates: DIMM ROM removal and installation, firmware downloading, service-label data restoration, and controller version compatibility.

• Parts identification: Exploded assembly drawings, plain/duplex applicability notes, connector lists, and numerical part-number indexes.

This set is suited to copier repair technicians familiar with service-mode diagnosis, electrical measurements, and specialized PCB test equipment.

Reader and Print-Quality Adjustments

Maintenance and inspection routines cover the Reader Unit, Printer Unit, and cassette pedestal, with scheduled service at 50,000-print intervals. Estimated replacement lives are listed for scanning lamps, air filters, transfer belts, rollers, and the fixing web.

Scanner coverage includes drive cable routing, lamp intensity adjustment, standard white plate data, and CCD-related settings. New-lamp adjustment is distinguished from adjustment after reinstalling an existing lamp; replacement follow-up includes auto gradation correction and head shading where specified.

Printer adjustments cover image margins and non-image widths from the cassettes, manual feed tray, side paper deck, and duplex unit. Drum unit and transfer belt replacement follow-up includes the associated service settings.

The LED exposure section covers mounting, cleaning, and post-replacement head shading. Its handling illustration identifies the lens surface and aluminum lens base as areas where touching can cause image faults.

Fixing, Paper Feed, and Electrical Fault Isolation

Fixing coverage separates web replacement after an E005 indication from routine replacement. Nip and skew illustrations support roller pressure checks, while manual feed procedures address timing belt placement and paper-width reference registration.

Photointerrupter tables connect sensor names to connector terminals, voltage readings, and I/O addresses. This lets a technician compare a paper-path sensor's electrical state with its service-mode indication when narrowing down a feed or duplex fault.

The Reader Unit General Timing Diagram, Printer Unit General Circuit Diagram, and Cassette Pedestal General Circuit Diagram show circuit connections and signal paths. Signal definitions include the CONT0 through CONT3 scanner-motor current-control lines; separate location drawings identify sensors, motors, and PCBs.

Service Modes and Controller Firmware

Status displays, jam and error histories, adjustment screens, test prints, component operation checks, and external-controller interface settings are documented separately. Error tables describe likely causes and detection conditions for copier faults, including E000 and E810, plus DADF, finisher, saddle stitcher, sorter, and PDL board faults.

Controller replacement sections address RAM initialization, service-label data restoration, and matching ROM versions across the reader, DC, and system controller PCBs. Downloading procedures call for a PC running the Copier Service Support Tool and an IEEE 1284-compliant bi-Centronics cable; interruption during a write can leave the DIMM unusable.

The appendices list solvents, oils, and special tools. Work around high-voltage supplies and heated fuser units requires electrical isolation and handling precautions appropriate to the service task.

Exploded Parts Drawings and Configuration Matching

The catalog includes the Color Image Reader-A1 and copier/printer assemblies, with CP2150/2120 listings. Separate sections cover the Cassette Feeding Unit-U1, Plain Pedestal-B1, Power Supply Unit-L1, Power Supply Unit-M1, and PDL Board-A1.

Assembly Location Diagrams, figure keys, quantities, and indexes connect components to their part numbers. Plain and duplex-type applicability notes distinguish paper-handling configurations before ordering.

Environment PCB Check Values: A Brief Preview

These examples are a small selection of the handbook's electrical test data. The environment measurement PCB check, performed with TKN-0457 in place of the sensor, specifies a 24 ± 2.4 V supply between J1-1 (+) and J1-2 (-).

Under that test setup, the documented ANALOG display readings are 25 ± 5°C for TEMP and 40 ± 10% for HUM. The separate sensor comparison procedure uses the TKN-0456 calibrating tool.

Searchable Text, Wiring Detail, and PDF Contents

Text search and circuit labels: Both publications have searchable body text. The file has no embedded PDF bookmarks, and small connector and pin labels in the full-page wiring diagrams require zooming.
