Ink-System Repairs and Service-Mode Checks

These are selected service procedures and references from the manual. It also covers hard drive erase options and a firmware download mode that bypasses initialization.

• Carriage and ink-system service covers disassembly and reassembly of the carriage, ink tube, purge, and ink tank units, with automatic and manual ink-draining procedures.
• Post-replacement adjustments cover the multi sensor, feed roller, head management sensor, and carriage motor. Separate routines handle head registration and paper-gap calibration.
• Electrical fault tracing is supported by connector drawings and pin assignments for the main controller, carriage relay, and head relay PCBs.
• Service-mode diagnostics cover sensor inputs, nozzle discharge, printhead contacts, and memory. Warning, error, and service-call tables link faults to checks and corrective actions.
• Maintenance and transport cover cleaning the paper path, tracking consumable parts, and preparing the printer for different moves and shipping conditions.

Canon wrote this manual for qualified personnel responsible for printer installation, maintenance, and repair.

Ink Delivery and Carriage Service

The Overview of Ink Passage traces the LUCIA EX system from the PFI-304 or PFI-704 tanks through the subtanks and supply valves to the two PF-05 printheads. It also shows the waste-ink route to the maintenance cartridge. The purge-unit section explains glycerin-assisted wiping and how the suction pump draws ink during filling and cleaning.

The Carriage Unit Disassembly Flow shows which assemblies must come out to reach the carriage. The repair notes cover carriage-belt installation, feed-motor timing-belt tension, release-lever gear alignment, valve motor removal, and manual uncapping. Moving the carriage while the heads are capped can press the cap rubber against the nozzles and damage them.

Canon refers technicians to a separate Parts Catalog for general disassembly and reassembly sequences and numbered parts layouts outside the main units covered here. Red screws mark factory-adjusted locations that are off-limits for field disassembly.

Calibration and Fault Diagnosis

The adjustment section identifies the work required after part replacement. It calls for a new multi-sensor reference plate (QL2-3279-000) when replacing the carriage unit or multi sensor and documents OPTICAL AXIS and GAP CALIB. Feed-roller eccentricity has separate automatic LF TUNING and manual LF TUNING 2 routines. The service menu also distinguishes the old and new feed roller types.

PRINT INF explains how to read fault histories, printhead records, and parts counters. The OPT SENS OUTPUT checks help distinguish a degraded multi sensor from incompatible media or interference from outside light. Clear film has its own check criteria.

Control Boards, Firmware, and Service Tools

The Printer Diagram, Print Signal Sequence, and Power Supply Block Diagram show how power and control signals move through the printer. The electrical reference includes board layouts, pin tables, and the Serial ATA hard-drive interface. Conductive ink can damage energized boards. Disconnect power before opening the chassis and observe Canon’s precautions around moving parts and exposed electrical components.

PCB replacement mode preserves settings and counters when the main controller PCB or maintenance cartridge relay PCB is replaced. Canon specifies replacing the boards separately. Firmware coverage includes startup and shutdown, printhead overheating protection, and updates over USB or a network using the imagePROGRAF Firmware Update Tool or L Printer Service Tool. The e-Maintenance/imageWARE Remote section covers e-RDS communication tests and error logs.

Lubrication drawings show where grease is applied. The tool list identifies the cover switch tool (QY9-0103-000), MOLYKOTE PG-641 grease (CK-0562-000), and PERMALUBE G-2 grease (CK-0551-020).

Paper Path, Cleaning, and Transport

The Structure of Feed Roller Unit shows how the drive components move the media. The paper-path section explains roll back tension, pinch-roller operation, and automatic cutting. The optional take-up unit has separate coverage for motor control and paper-detection sensors. Reference tables list media limits, electrical ratings, and installed dimensions.

Maintenance tables link waste-ink absorbers and fan units to part numbers and service counters. Cleaning procedures cover the platen, borderless printing ink grooves, and maintenance-jet tray. Transport guidance distinguishes same-floor moves, truck transport, air or sea shipment, cold-weather shipment, and end-on handling. The procedures address ink drainage, consumables, carriage restraint, and reinstallation checks according to the move.

Sample Multi-Sensor Readings and Purge-Unit Limits

For clear film, the OPT SENS OUTPUT reference lists a normal regular-reflection gain of about 10–60 and a media output reading of about 500–600 when the multi sensor and media are functioning normally.

The service-call table associates E141-4046 with 50,000 or more recovery rotations. That entry identifies purge-unit replacement and a parts-counter reset as the applicable service work.
