Ricoh N6076045B / AZ240092FL is a high-voltage power supply board, typically used in Ricoh multifunction printers (MFPs) or copiers. This module is responsible for generating and regulating high-voltage outputs required for image development processes such as corona charging, transfer, and fusing. Description: The board consists of multiple transformers, HV regulation sections, and filter components, often split into multiple zones for main charge, transfer, and bias voltage control. It includes shielding for noise-sensitive components, heat sinks, and EMI suppression circuits. Technical Specifications: Manufacturer: Ricoh Part numbers: – N6076045B (main identifier) – AZ240092FL (variant or subassembly code) Board function: High-voltage power supply unit (HVPSU) Input: Low-voltage DC (from main power supply or PFC board) Output: High-voltage DC (commonly in the range of 500V–2kV depending on application) Main sections: – Flyback transformers – Opto-isolators and HV diodes – EMI/RFI filters – HV output terminals (likely wired or routed to transfer/charge assemblies) Application: Used in Ricoh laser printers or copiers for: – Primary charge – Transfer bias – Toner/developer bias – Fuser control Construction: Includes grounded metal shielding for HV zones, thermal pads, and high-isolation PCB spacing Please review pictures carefully and let us know if you have any questions!
