2005 Canon iR2020/iR2016 Copier Service Manual (P/N 0011–0899)

This Canon service manual, dated October 3, 2005, covers the iR2020/iR2016 digital copier family, including the J-series and i-series variants identified in its sections. Regional installation and accessory information addresses North American, Latin American, European, and Asian configurations.

• Reader repair: Contact image sensor, reader controller PCB, and scanner motor replacement, with CIS output correction and ADF reading-position adjustment.

• Image formation: Laser scanner unit removal, drum and developing assembly replacement, transfer charging roller service, and charging and developing bias control.

• Fixing system: Fixing film unit and pressure roller disassembly, film-speed control, thermistor monitoring, heater protection circuits, and related error diagnosis.

• Paper handling: Cassette and manual-feed pickup assemblies, registration roller and clutch replacement, separation components, and configuration-specific paper paths.

• Diagnostic tests: Error and jam code tables, sensor status checks, D-RAM tests, print patterns, and modem/NCU transmission and reception tests.

• Controllers and accessories: Image processor, DC controller, and power supply PCB replacement, plus Card Reader-E1 registration and reader/cassette heater installation.

• System upgrades: Service Support Tool procedures for system, BOOT, and PCL software, with the connection requirements for Finisher-U1 updates.

Canon issued this manual for qualified service personnel working on technical theory, installation, maintenance, and repair.

Reader and Image Formation Repair

After board replacement: The image processor PCB procedure includes restoring service-label values, CIS inter-channel output correction, and ADF reading-position adjustment where fitted. Adjustment values are stored on the image processor PCB; replacing the reader controller PCB does not require the same data entry.

Developing assembly: Coverage extends to mounting alignment and the developer idling mode used after replacement. The installation chapter also explains this mode for low-temperature, low-humidity conditions that can produce light initial copies.

The drum handling notes identify a specific damage risk when the left door is not fully open during removal or installation. CIS replacement also requires inter-channel output correction through SCAN TEST, which matters when investigating uneven image output.

Fixing and Paper Feed Service

The fixing chapter goes beyond complete-unit replacement, showing access to the film assembly, pressure roller, springs, spacers, and sensor holder. Temperature-control explanations distinguish warm-up, paper-present, and sheet-to-sheet operation, along with cooling and slowdown behavior.

Paper-feed coverage includes cassette size detection, pickup solenoids, the registration clutch, and manual-feed separation pad replacement. Maintenance references identify replaceable durables, their part numbers and estimated service lives, and the associated DRBL-1 counters.

Electrical and Jam Diagnostics

Jam entries distinguish delayed arrival from paper remaining at a sensor. The Sensor Layout Drawing and Roller Layout Drawing support that logic, helping technicians identify the affected feed section before selecting an assembly for inspection.

Paper Path Drawings show routes with Duplex Unit-A1 and Finisher-U1 installed. Electrical drawings include the Image Processor PCB connector layout, high-voltage bias circuits, and the fixing heater protection schematic.

Service-mode coverage adds NORMAL and LATCH sensor monitoring, jam/error history reports, component counters, and ROM information.

These machines contain high-voltage components and laser sources. Follow the manual's electrical isolation and laser precautions before internal service.

Optional Equipment and Upgrade Requirements

J-series limitation: The iR2020J/iR2016J cannot be expanded with print or transmission functions. For the iR2020/iR2016, the accessory configuration identifies UFRII LT Printer Kit-J2, PCL Printer Kit-J1, and the Super G3 FAX Board-T1/FAX Panel-A1 combination.

Firmware procedures require a PC with Service Support Tool and the applicable system software. Finisher-U1 updating uses Downloader PCB FY9-2034 and an RS-232C connection. General fax faults beyond the product-specific entries are referred to the separate G3/G4 Facsimile Error Code List (Rev. 2).

A Sample of Power Supply Ratings and Protection Limits

These entries are a small selection of the manual's electrical reference data. The power supply's 24 V output has a rated current of 5.5 A and an output-voltage tolerance of +10%/-5%.

The table separately specifies an overcurrent-protection trigger of 8.0 A for that output.

Text Search, Bookmarks, and PDF Contents

Search and diagram detail: Service text supports PDF search, although text in some sample reports has search limitations. Embedded bookmarks cover all chapters and many subsections. The fixing heater schematic requires zoom to read small connector and pin labels.

One printable, English-language PDF contains 334 pages. The total includes 22 pages of cover and front matter, 15 chapter divider pages, 35 further blank or header-only pages, and two closing pages.
