Technical Documentation Scope

The 2008 Canon MP630 / MP638 service manual delivers essential technical specifications for maintenance and diagnostic support. It covers major components including the logic board, scanner unit, paper feed mechanism, and carriage assembly. Chapters clearly break down the system error code structure—separating Operator Call from Service Call classifications—alongside detailed flowcharts for mechanical issues like carriage errors or paper jams. Before proceeding with any internal checks, always ensure the device is completely disconnected from power to prevent electrical shock.

This OEM service publication outlines specific disassembly sequences for the external housing and operational panel. High-resolution imagery maps out internal components and complex cabling layouts. Get straight to work with the instant download provided directly upon purchase.

Diagnostic and Calibration Reference Values

Calibration data is thoroughly documented for multiple hardware conditions, such as logic board replacements, paper feed roller changes, and print head adjustments. You will find precise reference values for grease application using FLOIL KG-107A on the carriage rail and Easy-Scroll Wheel base. The manual defines print head alignment parameters for both standard manual and automatic methods, while also establishing ink absorber counter thresholds managed via the Service Tool. Finally, the internal inspection flow provides standard verification patterns to confirm print output quality and proper mechanical operation following any parts swap.
