2007 Canon imageRUNNER C3380 / C3380i / C2880 / C2880i Service Manual (P/N DU7-1192-010)

• Covers Canon imageRUNNER C3380, C3380i, C2880, and C2880i multifunctional console systems and Cassette Feeding Unit Y1/Y2/Y3 configurations. An 811-page PDF of Canon service manual DU7-1192-010, Revision 1 (June 2007).
• Reader and laser sections cover CIS and laser scanner unit replacement, reader controller PCB service, and the associated shading and calibration adjustments.
• Process unit and intermediate transfer belt (ITB) unit removal, drum replacement, and transfer-cleaner service are documented alongside toner supply and waste-toner detection controls.
• Paper-feed repair addresses cassette pickup, feed and separation rollers, manual feeding units, registration control, and the duplexing path, with jam-detection logic.
• Fixing unit, fixing film unit, and pressure roller replacement procedures include nip width confirmation, temperature-control descriptions, and protective functions.
• Error-code tables and service-mode references cover jam/error histories, sensor I/O displays, and PART-CHK operation tests for motors, fans, clutches, and solenoids.

System Architecture and Operations

This documentation breaks down the main controller board functions, image processing data flow, and power-on and print-job sequences. The Connections Among Major PCBs diagram maps the board interconnections; Flow of Image Data for SEND Functions traces the transmission processing path. Separate sections address fax transmission and reception.

Controller repair coverage includes main and sub PCBs, SRAM, boot ROM, image memory, and HDD replacement. Network troubleshooting includes PING checks using remote, loopback, and local host addresses.

E602 Diagnosis, MEAP, and Software Recovery

The HDD sections distinguish E602 subcodes for drive recognition, WriteAbort, and file-system faults, with partition-specific recovery procedures. MEAP coverage extends to application and license management, safe mode, and backup/restoration through the Service Support Tool (SST).

SST procedures also cover reader and DC-controller backup data. The upgrading chapter documents system-software installation, HDD formatting, and USB updating. System-software files and service tools are separate requirements for these procedures.

Image Quality and Electrical Fault Tracing

PASCAL automatic gradation correction is covered alongside color-displacement correction and toner-density control. Secondary-transfer roller replacement has its own TNR-COAT conditioning procedure.

The Full Page Halftone and Grid test prints support diagnosis of density, transfer, and registration defects. Appendix references include General Timing Chart sheets for reader and printer operation and General Circuit Diagram wiring sheets covering power, controller, high-voltage, and fixing circuits. Exploded-view diagrams and assembly drawings accompany the component replacement sections.

The repair notes warn that closing the right cover with the process unit out of position can let the secondary-transfer high-voltage contact puncture the ITB. Incorrect installation of the fixing shutter assembly can also damage the fixing film.

Technical Specifications and Maintenance Data

Specification tables cover operating conditions, power consumption, memory configurations, supported media, registration tolerances, and electrical reference values for secondary transfer bias generation. Maintenance coverage includes durables and consumables, replacement guidelines, service-life counters, and scheduled cleaning and inspection of reader and printer units. Different fixing-film part numbers are listed for the regional supply-voltage versions.

The special-tools references identify the CA1 test sheet (FY9-9030) for image checking and adjustment and the D-10 test sheet (FY9-9129) used for CCD gain correction.

Accessory Configurations and Coverage

Installation procedures cover Card Reader-C1, which requires Card Reader Mounting Kit-B1, plus Voice Guidance Kit-B1 and Voice Operation Kit-A1. DADF-L1 installation includes reading-position, reproduction-ratio, and white-level adjustments.

The accessory compatibility table identifies specific mounting restrictions: neither voice kit can be combined with Document Tray-J1, and the two voice kits cannot be installed together.

Finisher-Z1, Finisher-Y1, and Saddle Finisher-Y2 are addressed through system configurations, paper paths, error diagnosis, and service-mode settings. This is the main-unit service manual, not a set of separate finisher teardown manuals.

Keep in mind that working with high-voltage generation blocks and laser scanner assemblies carries inherent risks; always ensure power is isolated and standard workshop safety protocols are followed before inspecting internal electrical circuits.
