## Summary description

Replacement mainboard (logic board) OKI 45724902 designed for OKI B412 series printers. It serves as the printer’s central control board, handling communications, print job processing and device interfacing. Use this genuine mainboard to restore functionality after board failure, enabling reliable printing performance and compatibility with original hardware.

## Long description

Replacement mainboard for OKI B412d, B412dn and B412dtn series printers. This printed circuit assembly is the central control board that manages communication between the printer’s interfaces, processes incoming print jobs, and coordinates mechanical and electronic subsystems to restore normal device operation after a board failure. The mainboard is compatible with the listed OKI models and intended to return original functionality when fitted according to manufacturer procedures.
Advantages
The mainboard restores full control-layer functionality, including job spooling, interface handling and status reporting, enabling the printer to resume reliable operation with original firmware and hardware compatibility. Using a direct replacement board avoids extended diagnostics of multiple subsystems and can be more time- and cost-effective than replacing the entire printer. The board is designed to match the physical connectors and mounting points of the OKI B412 series for straightforward installation by a qualified technician.
Suitable for
Repairing OKI B412d, B412dn or B412dtn printers with board-level failure
Service centers performing mainboard replacement and firmware restoration
IT departments restoring networked monochrome printers in small offices
Technicians replacing a defective logic board to recover device functionality

How to use
Power off the printer and disconnect it from the mains before starting any repair. Remove the printer covers to access the internal electronics following the service manual instructions for the OKI B412 series. Carefully disconnect ribbon cables, connectors and any attached modules, noting their positions. Unfasten the mounting screws and extract the defective mainboard. Install the replacement board by aligning connectors and mounting points, secure with screws, reconnect all cabling, reinstall covers and power on. After installation, verify firmware version and device settings; if required, perform firmware reinstallation or configuration using the manufacturer’s tools to restore network and printing parameters.
Usage recommendations
Installation should be performed by a trained technician or service center familiar with OKI printers. Use antistatic handling precautions and follow the OKI service documentation. After replacement, run basic diagnostics and test pages to confirm functionality. If network or firmware issues persist, consult official OKI support for firmware images and configuration guidance.
