Canon iR8500 / iR7200 Factory Service Manual – 2001 (P/N FY8-13H3-010)

Canon’s factory service manual for the 2001 iR8500 and iR7200 covers installation, maintenance, troubleshooting, and repair. This is Revision 1 (P/N FY8-13H3-010), issued in August 2001.

Searchable Text and Chapter Bookmarks

Text search and diagram detail: The manual text is searchable, and bookmarks open the chapters, Service Mode, and Error Code sections. Text inside software screenshots is image-based. Small pin, connector, and signal labels in the appendix circuit diagrams are readable when zoomed in.

The download is one printable 813-page PDF, including the front cover, copyright page, publication credits, and back cover.

Reader, Print Engine, and Paper Path Service

These selected procedures and references show the work covered in the manual. Other sections cover relocating the copier and list the solvents and oils used in service.

• Reader and scanner: Step-by-step removal and installation, scanner-drive cable and mirror positioning, original-size detection, shading correction, and CCD gain adjustment.

• Print engine: Twin-laser and beam-detect (BD) unit service, process-unit and drum disassembly, charging-wire setup, developing-system service, surface-potential checks, and fixing and delivery adjustments.

• Paper feed and duplexing: Deck, cassette, manual-feed, vertical transport, and registration service, with roller orientation and pressure checks, belts, solenoids, and duplex assembly work.

• Side Paper Deck-M1: Pickup and lifter troubleshooting with checks for the drive belt, clutches, switches, and deck driver PCB.

• Electrical diagnostics: Model-specific PCB input/output diagrams, component maps, sensor tests, and error-code references for isolating copier and controller faults.

• Controller and firmware: HDD and board replacement, system software and ROM upgrades, and settings backup and restoration with Canon’s Service Support Tool.

Canon wrote this manual for qualified copier service technicians.

Reader Differences and Option Coverage

Both copiers share GP605-derived print-engine hardware. The iR8500 converts four CCD channels to two, detects dust during stream reading, and has scanner-motor cooling. Its CCD adjustment procedures address the visible line that can appear at the sensor seam after CCD/AP or reader-controller board replacement.

The iR7200 uses the iR5000i/6000i exposure design. Its reader section covers the xenon lamp, scanner motor and cable, CCD/AP board, and reader controller.

The iR8500P appears in shared installation procedures, and the iR8500B appears in the installation package list. The iR8500 uses the DADF-J1, while the iR7200 uses the DADF-D1. Internal service for the DADF, finisher, folding unit, and inserter requires the respective option manuals. This volume covers installation of the Card Reader-D1, NE Controller-A1/B1, Copy Data Controller-A1, and Network LIPS Printer Kit-B1.

Image Faults and Paper Jams

Image-fault tables cover light, fogged, lined, spotted, blank, solid-black, poorly fixed, and misregistered copies. Image-position adjustments are documented for printer, book, and ADF modes. Separate tables address power loss, scanner and lamp faults, toner feed, jams, double feeding, and wrinkles.

The Side Paper Deck-M1 construction and control diagrams help trace a pickup failure from the mechanical drive to the clutch circuit or driver board. Photointerrupter checks identify the connector, voltage, and Service Mode I/O state. The manual also provides a separate environment-sensor test.

Controller Recovery and Scheduled Maintenance

The main-controller chapter covers startup, image processing, memory control, power modes, and counters. The HDD doubles as image memory for sorting. System software must be reloaded after HDD formatting to avoid E602-0002. The software sections cover Remote UI, language modules, BOOT ROM, and DIMM/ROM upgrades, including how to match software to the copier model and COPY/PRINTER configuration.

The Service Support Tool backup lets technicians restore user, service, and machine data after main-controller board replacement. Service Mode covers COPIER display, I/O, adjustment, function, option, test, and counter menus, plus FEEDER, SORTER, and BOARD. Scheduled-service charts and work procedures identify consumables, durable parts, and items due for replacement.

Diagrams, Special Tools, and Repair Notes

The appendix pairs general timing charts and circuit diagrams with a signal list. Other diagrams show four-channel CCD data transfer, twin-laser exposure, and the image-formation sequence. The Special Tools Table lists the FY9-3040 mirror positioning tool, FY9-4008 laser power checker, FY9-3041 potential-sensor tester electrode, FY9-3014 environment-sensor meter, and factory image test sheets.

Reader repair notes explain how contact can contaminate or damage the lamp and optical surfaces and why No. 1 and No. 2 mirror positioning matters during cable replacement. Post-replacement instructions cover the controller boards, HDD, high-voltage DC PCB, laser unit, and matched potential sensor and control board.

Electrical and Laser Safety

These copiers contain high-voltage charging circuits, laser components, energized heater circuits, and a hot fixing assembly. Disconnect the wall plug before disassembly. Laser, high-voltage, and live-circuit work is for qualified service personnel.

Fixing Nip and Laser Check Examples

For the lower fixing roller pressure check, the center nip width on the A3 test print is 9.0 ± 0.5 mm with both rollers fully heated. At the two points 10 mm in from the paper edges, the nip widths should differ by no more than 0.5 mm.

For the twin-laser check, the specified power checker and digital multimeter should give a reading of 9–11 mV for each beam.
