Canon imageRUNNER 5075/5065/5055 Service Manual (P/N DU7-1213-000)

• Official publication and model coverage: Canon's 799-page PDF, publication DU7-1213-000, February 2007, Rev. 0, covers the imageRUNNER 5075, 5065, and 5055. Model-specific tables also reference the iR5075N, iR5065N, and iR5055N and separate certain high-voltage parts, procedures, and service data between the 5075 and 5065/5055 groups.
• Image-system repair: Covers the CCD reader, scanning lamp and drive cable, laser scanner, photosensitive drum, corona charging units, developing assembly, transfer/separation system, and drum cleaner, with removal, replacement, potential-control, shading, density, and image-position procedures.
• Paper path and fixing service: Details the integrated right/left decks, cassettes 3 and 4, manual feed, registration, duplexing, reversal/delivery, and IH fixing system, including jam detection, roller/motor/sensor replacement, fixing-roller and heater service, cleaning-web work, and related adjustments.
• Controller and software work: Includes main controller PCB, SDRAM, boot ROM, HDD, video PCB, DC controller, and power-supply replacement, plus MEAP/SMS application and license management, e-RDS communication troubleshooting, backup/restore, HDD formatting, and system-software downloads with Canon's Service Support Tool.
• Factory diagnostics and adjustments: Provides detailed machine, SEND, finisher, and ADF error/jam codes; DISPLAY, I/O, ADJUST, FUNCTION, OPTION, TEST, and COUNTER service modes; faulty-image checks; component maps; test prints; and adjustment data for the reader, image formation, fixing, and pickup systems.
• Installation and accessory setup: Walks through site checks, unpacking, host-machine assembly, scanner/fixing/developing/pickup installation, toner stirring, cassette and deck setup, image-margin adjustment, network testing, Card Reader-C1 and imageWARE Accounting Manager setup, document-tray installation, and Voice Guidance Kit-B1 installation.
• Technical drawings and reference data: Named references include the Wiring Diagram of the Major PCBs, Flow of Image Data diagrams, Arrangement of Rollers and Sensors, Distribution of Power and the Switches, General Timing Chart, and appendix General Circuit Diagrams.

Hardware Configuration and Machine Setup

Canon issued this service manual for qualified personnel learning the machines' technical theory, installation, maintenance, and repair. Its service-mode, laser, high-voltage, and software procedures are suited to technicians with copier repair training and the specified test equipment, not to beginners working without electrical and mechanical service experience.

The 120V configuration pages map the supported Finisher-AD1, Saddle Finisher-AD2, Puncher Unit-AT1, Document Insertion Unit-E1, Document Insertion/Folding Unit-F1, Paper Deck-AD1/AE1, DADF-S1, fax, printer, security, and transmission options. Full installation coverage in this volume is limited to the host machine, Card Reader-C1, Document Tray-K1/M1, and Voice Guidance Kit-B1. The external finishers, puncher, insertion/folding equipment, DADF, and add-on paper decks require their own accessory service literature for internal repair or complete installation procedures.

Specification, Maintenance, and Service Detail

The specification tables cover paper sizes, weights, feed sources, output speeds, image margins, resolution, capacity, memory and HDD configuration, regional power requirements, operating environment, dimensions, and weight. Maintenance material includes periodically replaced parts, durables and consumables, scheduled service charts for the reader and printer units, cleaning points, and post-replacement standards.

Canon's special-tool list identifies the FY9-3009 mirror positioning tool, FY9-9196 NA-3 Test Sheet, FY9-3012 potential-sensor electrode, FY9-3014 environment-sensor checker, and FY9-3038/FY9-3039 tester extension pins, along with specified cleaners, greases, and lubricants.

The manual flags two repair traps: striking the HDD against the counter-memory PCB during removal can cause impact damage, while inserting the pre-transfer charging assembly at an angle can scratch the photosensitive drum. It also requires the controlled shutdown sequence before power removal because interrupting HDD access can produce an E602 fault. Follow Canon's grounding and power-isolation requirements before internal service; the laser, high-voltage charging system, and induction-heated fixing unit require trained handling, and the laser scanner is not field-adjustable.
