Canon Pro9000 Mark II Service Manual (P/N QY8-13CH-000)

Deciphering alternating LED blink cycles instantly isolates faulty sensors before you even remove the external housing, directly increasing your shop's turnaround efficiency. This official 56-page Canon Pro9000 Mark II OEM PDF publication (P/N QY8-13CH-000) is the definitive reference used for the 031509 build, providing the exact technical data required for successful logic board replacement and detailed printer maintenance.

By detailing specific Service Tool V1.030 operation procedures, this documentation allows you to bypass authorized repair centers. It directly reduces bench time by providing the exact workflows to clear fatal lockouts—such as the service call error 5B00 (ink absorber full) or a carriage lift mechanism failure—and complete critical bench repairs without relying on trial-and-error parts swapping.

Component Diagnostics and Teardown

Designed for qualified technicians and serious DIY mechanics, this manual details 21 sensor function diagnostics, 34 error-display diagnostic codes, and 15 major component replacement procedures.

You get complete disassembly sequences for the external housing, carriage unit, ASF unit, purge unit, and platen assembly. To ensure successful shop-level maintenance, the documentation covers the removal, installation, and diagnosis of these critical internal components and system errors:

• Logic board assembly
• Paper feed motor unit
• Spur base lift unit
• Feed roller assembly
• Timing slit strip film
• Print head and ink tanks
• Sheet feed unit
• Front door unit, inner cover unit, carriage motor, pressure roller assembly, LF/EJ timing sensor unit, timing slit disk feed film, rear tray holder R unit, eject encoder sensor
• Operator call errors, service call lockouts, B200 VH monitor errors, 5100 carriage encoder faults, 6000 line feed errors, 5C00 purge cam sensor failures, 6502 ink tank position errors, 5400 internal temperature errors, 6A00 AP position sensor faults

The technical documentation goes far beyond basic text, utilizing component location views, nozzle check pattern charts, grease application views, LF/Eject correction pattern layouts, EEPROM information print samples, service test print charts, CD-R check pattern prints, and standard inspection flow charts to guide your workflow. It specifies precise grease application points and dictates exact milligram amounts for highly specific lubricants, including MOLYKOTE PG641 and FLOIL GP-1000R, alongside crucial applications for FLOIL KG-107A, EU-1, and MOLYKOTE HP300, across 25 distinct locations.

Specification and Initialization Settings

Critical alignments and post-repair settings are clearly mapped out. Adjustments cover logic board replacement parameters and ink absorber counter initialization. The included verification flow chart ensures standard inspection protocols are met regarding proper printing, communication, and carriage locking for safe transport.

Stop outsourcing complex calibrations to specialized facilities. This document outlines the step-by-step diagnostic and calibration procedures to perform high-level service tasks directly from your bench, eliminating expensive workshop labor fees:

• Waste ink absorber counter resetting
• EEPROM initialization and destination settings
• LF/Eject correction pattern calibration
• Automatic and manual print head alignment
• CD/DVD print position sensor correction
• Paper feed motor belt tension adjustment
• CD/DVD detection sensor light volume correction

Additionally, detailed diagnostic routines are included for PictBridge and USB communication issues, carriage lift sensor malfunctions, and CD-R tray detection problems. You will also find EEPROM information print data essential for ROM version identification and ink system function checks.

• Factory benchmarks dictate EEPROM initialization and destination settings take a precise 1-minute service workflow.
• Capacitor discharging requires approximately 1 minute before logic board removal to prevent electrical damage.
• The eject roller shaft adjustment plate must be precisely aligned during platen unit installation to prevent shaft bending.

Please remember that internal printer maintenance involves moving parts and sensitive electrical components. Always verify your technical skill level and consult a certified professional before performing complex service to ensure personal safety and prevent equipment damage.
