Canon imageCLASS MF6500 Series Service Manual Set (2006)

The Service Manual explains how the printer works and documents component replacement. The Portable Manual brings together service settings, adjustments, jam codes, and test modes for quick reference. The Basic Guide covers everyday operation and owner maintenance.

Scope: The MF6570 appears in the firmware compatibility table. Canon covers the factory-adjusted laser scanner at the assembly replacement level. The set excludes the parts catalog, Starter Guide, Advanced Guide, Scanner Driver Guide, Service Support Tool software, and firmware files. The Service Manual refers technicians to the separate G3/G4 Facsimile Error Code List (Rev. 2) for additional fax codes.

PDF Search, Bookmarks, and Download

Text search and diagram labels. All three PDFs have searchable text and chapter bookmarks. Small connector labels in the service diagrams are readable when zoomed. Some passages in the Service Manual’s fixing-control chapter display garbled characters.

The ZIP contains three printable English-language PDFs totaling 512 pages. The total includes the covers and date pages, 56 blank pages, and the Basic Guide’s appendix.

Feeder, Fuser, and Controller Service

These selected topics show the types of repairs and checks covered. The service material also includes drum-cleaning settings and service-mode parts counters.

• Reader and document feeder: Contact sensor and reader motor replacement, feeder drive access, and removal of ADF pickup and feed rollers, separation pads, solenoids, and sensors.
• Paper path and fuser: Cassette and multipurpose pickup components, registration clutch, duplex drive, transfer charging roller, fixing film unit, and pressure roller.
• Circuit boards: Replacement procedures for the image processor, DC controller, power supply, network, modem, and fax line interface boards.
• Fault diagnosis: Machine and fax error codes, main-body and ADF jam tables, error-history reports, and service tests for memory, scanning, printing, modems, sensors, and the operation panel.
• Electrical and mechanical references: Main-body and ADF cross-sections, a functional block diagram, power-distribution diagrams, and component maps keyed to connector numbers.

Canon wrote the service publications for qualified printer technicians. The Basic Guide is for operators handling routine use, cleaning, and jam removal.

Model and Hardware Differences

The Basic Guide covers fax and PC faxing on the MF6550, MF6560, and MF6580. PCL5e and PCL6 printing apply to the MF6560 and MF6580. Network functions and Remote UI apply to the MF6580.

The service references distinguish controller boards by PCL and network configuration and identify voltage-specific fixing units. They also identify the optional Cassette Unit-M1 and show where the Hand Set CT-25 is standard or optional.

Calibration and Firmware After Repair

Factory procedures cover CIS shading correction, ADF skew and magnification, side and leading-edge registration, and duplex parallelism after fixing-unit installation. The service tools listed include the NA-3 Test Chart FY9-9196 and digital multimeter FY9-2002.

Image processor board replacement calls for model-matched system and boot firmware, PCL firmware where fitted, and language files via the Service Support Tool. Canon also documents restoring service-label values and read-position adjustments. USB export and import preserve the address book and user settings around an all-clear.

An interruption during flash-ROM writing can prevent startup and require image processor board replacement. Repeated power-supply resets while a short remains can blow the board’s internal fuses.

Jam Diagnosis and Electrical Checks

Fault tables distinguish fixing-temperature faults E000–E003, main motor fault E010, and laser beam detection fault E100, along with controller, network, and modem communication faults. Fax diagnostics cover NCU relay checks, DTMF, G3/V.34 modem tests, and telephone-line signal detection.

The System Dump List, JAM/ERR LOG REPORT, and Service Label document communication results, jam history, firmware configuration, and saved adjustments. The sensor and actuator lists tie faults to component locations, part numbers, and connector jacks. For example, a 0104 paper pickup delay points to registration sensor SR11, which the component map traces to J202 on the relay board.

For internal service, Canon specifies disconnecting mains power and observing the fixing-unit heat and laser precautions.

Operation, Network Settings, and Maintenance

The Basic Guide explains panel controls, sleep and auto-clear timers, document limits for the platen and ADF, and media requirements for the cassette and multipurpose tray. It covers copy, scan, and print operation, plus speed dialing, group dialing, fax reporting, memory reception, and destination restrictions. MF6580 settings include TCP/IP, LPD and RAW printing, SNMP, and IP and MAC access filtering.

Owner maintenance covers Canon Cartridge 106 replacement, toner status, fuser roller and ADF cleaning, and document and paper jam removal. Canon distinguishes starter and replacement cartridge yields and identifies the ISO/IEC 19752 test basis. Reference tables also give operating conditions, scan and print resolution, and print speeds by paper type and size.

ADF Alignment and Power-Supply Values

For the LaserBase models listed in the service chapters, Canon specifies an ADF skew difference of 0 ± 1.5 mm between two measurements on an A4 or Letter test copy. The horizontal registration target on a feeder test copy is 10 ± 2 mm.

The power-supply board table gives the 24 V rail an output tolerance of +10%/−5% and an overcurrent protection threshold of 7.0 A.
