1999 Canon NP6512/6612/7120/7130/7130F Service Manual (P/N FY8-13GB-000)

This 1999 revision serves as the primary reference for the 14B-series image formation architecture. It outlines the factory setup, diagnostic logic, and component breakdowns for the complete range of desktop copiers—from the 250-sheet to 500-sheet cassette models. Navigating the internal circuitry of commercial copiers involves exposure to high-voltage blocks, making standard workshop safety precautions essential when reviewing these factory schematics.

• Documents the 1999 Canon NP6512, NP6612, NP7120, NP7130, and NP7130F series.
• Official Canon publication P/N FY8-13GB-000, Revision 0, August 1999.
• Features 56 individual wiring diagrams and 27 detailed timing charts for image formation cycles.
• Includes 12 specific circuit board pinout tables for the DC controller PCB.
• Provides 426 pages of technical breakdown covering mechanical, electrical, and optical system principles.

Operational System Data

The publication details the functional construction of the copier. It breaks down the image formation, exposure, and pickup/feeding blocks. Chapters deliver deep insight into the electrical circuitry and microprocessor-driven control signals routed between the DC controller PCB and the composite power supply. The manual provides a complete overview of the SURF fixing assembly and primary charging roller. It also outlines the scanner drive assembly along with its mirror and lens mechanics, mapping out the logic behind zoom functions and reproduction ratio adjustments.

Technical data anchors the documentation. It illustrates exact electrical parameters and mechanical tolerances for each machine. The main motor process speed is specified at 96 mm/sec, with defined operating conditions strictly between 7.5°C and 32.5°C. Primary charging roller DC bias hits -1376 V in image areas. The text provides specific adjustment values for different density modes. Fault code logic is heavily documented. For instance, it breaks down the E010 main motor fault code logic and E220 scanning lamp activation errors. This data is critical for isolating issues within sensor arrays, solenoids, and high-voltage circuit blocks.
