Canon FM1-D805-010 2ND TRANSFER H.V. PCB

For technicians and service centers that demand exacting OEM-grade repair components, the Canon FM1-D805-010 2nd Transfer High Voltage PCB stands apart as a precision-engineered board specifically tuned for the second transfer stage in Canon electrophotographic imaging devices. Unlike generic high-voltage boards that approximate voltage curves, this unit delivers the precise kV output and timing required to pull toner from the transfer belt onto paper with uniform density, preventing faded patches, ghosting, or incomplete transfer across the page. Built on a robust FR-4 substrate with a mixed-signal layout, it integrates power regulation, feedback sensing, and digital control in a single compact assembly, ensuring stable operation even under continuous print loads.

Highlights

• OEM part number FM1-D805-010, guaranteeing exact fit and electrical compatibility with designated Canon laser printers and MFPs.
• High-voltage output in the kilovolt range, precisely calibrated for second transfer bias in Canon imaging systems.
• Mixed-signal circuitry combines high-voltage generation, current sensing, and logic interface for reliable closed-loop control.
• RoHS compliant construction with multi-layer FR-4 board for durability and thermal stability.
• Multiple multi-pin connectors for secure power and signal integration, designed for internal chassis mounting.

In daily use

Installed inside a compatible Canon device, this board silently manages the second transfer voltage during every print cycle. When the printer is powered on, the board receives device-specific DC input and converts it to the high-voltage potential needed at the transfer roller. Its sensing circuits monitor output and adjust in real time to compensate for environmental changes such as humidity or paper type, maintaining consistent image quality. Because it is a direct replacement for the original component, installation follows standard service procedures—remove the old board, secure the new one with the existing screw mounts, and reconnect the harnesses. The result is a restoration of factory print performance without the need for firmware changes or calibration beyond routine service adjustments.
