2007 Canon PIXMA MP970 Printer Service Manual & Parts Catalog

The 2007 Canon PIXMA MP970 Service Manual and Parts Catalog covers error-code diagnosis, component replacement, adjustment, and repair verification for the MP970 multifunction printer. Both publications carry Canon U.S.A. copyright 2007.

• Error diagnosis: Operator Call Errors, Service Call Errors, and symptom-based troubleshooting for print quality, paper feeding, scanning, and network printing.

• Mechanical repair: Photo-guided removal of the external housing, scanner unit, document cover, and operation panel, plus printer-unit separation from the bottom case.

• Logic board and ink system: EEPROM initialization, destination settings, ink absorber replacement and counter management, and checks following logic board replacement.

• Print and feed adjustments: Automatic and manual print head alignment, paper feed motor adjustment, LF/Eject correction, and platen-unit service checks.

• Scanner and controls: Document pressure plate adjustments, Film Adapter Unit troubleshooting, and button, LCD, and Easy-Scroll Wheel testing.

• Parts identification: 14 illustrated parts figures with exploded views, component numbers, harness connections, and assembly details for repair planning.

Canon identifies this publication as reference material for its authorized service facilities; its internal repair and service-mode procedures are intended for service personnel.

Diagnostics and System Maintenance

The error tables connect LCD messages and LED blink cycles with fault conditions and likely replacement parts. Carriage error 5100, line-feed error 6000, and purge-cam sensor error 5C00 have separate entries, helping you distinguish these fault areas before selecting parts.

EEPROM and ROM/RAM errors are covered alongside ink-tank recognition, scanner home-position, and paper-eject encoder faults. Symptom-based troubleshooting addresses banding, missing colors, smeared output, carriage noise, and scanning defects.

Network troubleshooting separates USB test printing from LAN-setting checks. The manual identifies the main logic board as the location of the network function and includes LAN resetting and settings-information display.

Component Removal and Repair Precautions

Photographic documentation shows removal access and cable harness routing around the scanner, operation panel, and printer unit. The bottom-case separation procedure explains access to the screw beneath the purge unit.

Replacement notes cover the carriage unit, platen unit, and timing slit strip, disk, and eject films, with the associated adjustments and operation checks. The lubrication reference specifies FLOIL KG-107A (tool number QY9-0057-000), application points, and quantities for the carriage mechanism and Easy-Scroll Wheel.

Servicing internal electronics carries shock risks; verify that the unit is disconnected from its power source before opening the casing. The repair notes also warn that residual capacitor charge can damage the logic board and that the LCD hinge flexible cable is vulnerable during panel removal.

Service Settings and Post-Repair Checks

Logic board replacement is tied to EEPROM settings, ink absorber counter handling, ink system function checks, and print verification. The manual distinguishes retaining absorber usage data after a board change from resetting the counter after absorber replacement.

The LF/Eject correction flowchart supports adjustment after feed-roller, logic-board, or platen-unit replacement. Left margin correction includes cassette and duplex-printing flowcharts, although the service-mode table marks this function as not used in servicing.

Destination settings distinguish regional CD/DVD-print support, including US and Canadian settings without disc printing. Service test prints, EEPROM information prints, and ink absorber counter printouts provide verification records; the button and LCD test also covers wheel response and display flicker adjustment.

Parts Catalog and Connection Views

The catalog includes External Covers & Scanner Unit, Card Board Ass’y & IrDA Board Ass’y, Purge Unit, and Paper Feed & Carriage Lift Part illustrations. It identifies print head QY6-0062-010 and logic board assembly QM3-2237-000 as replacement components.

Electrical coverage consists of cable-routing photographs and connector references in the parts views; circuit-level schematics are not included. Transportation notes address carriage restraint, scanner locking, and print-head protection after repair.

PDF Search, Navigation, and Page Count

Main text and parts lists are searchable, and 46 embedded bookmarks cover both sections; some flowcharts, drawing labels, and test-print samples are not searchable. Small connector labels in the parts views are easier to read when zoomed in, and printed service pages 42 and 43 appear in reverse order. The 55-page PDF contains the 47-page Service Manual (45 numbered pages, cover, and contents) plus the 8-page Parts Catalog (seven numbered pages and cover), with all cover and contents pages included in the total.
