2007 Canon imagePROGRAF iPF8000S Large-Format Printer Service Manual (P/N DU7-1245-000)

Canon’s service manual for the imagePROGRAF iPF8000S covers technical theory, installation, maintenance, and repair. The document is identified as DU7-1245-000, Rev. 0, October 2007.

• Ink delivery and recovery: Ink tank and subtank operation, purge-unit servicing, maintenance-cartridge handling, and automatic or manual ink draining.

• Carriage and media feed: Carriage and ink-tube removal, feed-motor installation, encoder handling, and adjustment requirements after component replacement.

• Printhead calibration: PF-03 replacement, optical-axis correction, paper-gap calibration, feed-roller eccentricity adjustment, and head management sensor alignment.

• Control electronics: Main controller, carriage relay, and head relay PCB connector locations, pin assignments, signal functions, and board-replacement procedures.

• Service diagnostics: Service-mode maps, sensor and switch I/O displays, error histories, consumable counters, diagnostic printouts, and firmware update procedures.

• Installation and transport: Stand, basket, and optional media take-up installation, relocation preparation, ink-draining requirements, and post-installation print checks.

Canon wrote this manual for qualified service personnel learning the printer’s technical operation and performing installation, maintenance, and repair.

Carriage, Ink Delivery, and Adjustment Work

The disassembly chapter provides illustrated flows for the carriage, ink tube, purge, and ink tank units. Additional notes address feed-motor timing-belt installation, feeder handling, the linear encoder, and the head management sensor. Other disassembly sequences refer to a separate Parts Catalog that is not included in this PDF.

After parts replacement: Carriage and multi sensor work is linked to OPTICAL AXIS correction and GAP CALIB. Feed-roller and encoder replacement calls for LF TUNING, with LF TUNING2 documented as the manual alternative. The head management sensor has a separate NOZZLE CHK POS. adjustment.

The adjustment table connects replaced components to their required calibration, helping technicians select the appropriate checks for paper-feed accuracy and head-to-media measurement after repair. Media settings also address skew-check sensitivity and platen vacuum strength.

Ink-system coverage explains subtank supply, pigment agitation, suction, capping, wiping, and maintenance-cartridge monitoring. Manual ink drainage is documented for situations where electrical or firmware faults prevent normal operation.

More than 40 mechanical illustrations show component locations and assembly details. The carriage-removal notes identify the linear scale as particularly vulnerable: scratches can cause malfunction.

Control Electronics, Diagnostics, and Diagrams

The technical reference follows image processing, bidirectional print control, hard-disk job storage, and communication between the main controller PCB and sensor circuits. Service-mode I/O displays identify individual sensor and switch states, while separate tables distinguish warnings, errors, and service-call conditions.

PCB replacement: The main controller and maintenance cartridge relay PCB retain settings and usage information for transfer during replacement. Replacing both together can lose the information needed to configure the replacement boards.

Firmware update procedures cover the GARO Firmware Update Tool and L Printer Service Tool. Interface specifications include signal-level and connection information for USB, Ethernet, and optional IEEE1394.

Electrical references include the General Circuit Diagram sheets, Power Supply Block Diagram, Print Signal Sequence, and Print Drive Timing diagram. The Color Calibration Print Chart and Printhead Adjustment Patterns support interpretation of calibration output. Connector tables identify pin numbers, signal directions, and functions for the main controller and relay boards.

Installation, Transport, and Maintenance

Relocation tables distinguish movement across a level floor from truck, air, sea, and upright transport. They explain differences in ink handling, maintenance-cartridge preparation, carriage securing, and separation of the printer from its stand.

Consumables tables pair part numbers with service-life information and counters. Cleaning coverage addresses ink mist, paper dust, platen vacuum holes, and borderless-printing ink grooves.

The lubrication table distinguishes light Molykote PG-641 application on the carriage joint-base rail and rib from specified Permalub G No. 2 quantities elsewhere. The service-tool list also identifies cover switch tool QY9-0103-000.

Internal power-supply work and lifting the printer require the electrical and handling precautions described in the manual.

Selected Head-Height and Operating Specifications

These examples are a small selection of the manual’s clearance and operating data. The carriage-height table lists 2.0 mm (Standard) for plain paper, coated paper, and fabric banner, and 2.6 mm (Highest) for canvas.

These media-specific values accompany the explanation of automatic carriage-height control. The operating specification also lists printing noise at approximately 50 dB(A) or less.

Searchable PDF and Circuit-Diagram Access

Text search, bookmarks, and diagram detail: The PDF contains searchable text and bookmarks for chapters and the appendix. The Error Table and Service Call Table sub-bookmarks have incorrect destinations; those tables begin on PDF p. 322 and PDF p. 328, respectively. Small circuit labels require zooming for comfortable reading.

The download is a single, printable 338-page PDF in English. The total includes the front matter, the nine-page appendix comprising a divider and eight circuit-diagram sheets, and the back cover.
