Listing details
Review the original listing for condition, specifications and included components.
Up for sale is a genuine OEM HP DC Controller PCB Board Assembly, pulled cleanly from a working HP Color LaserJet Pro MFP M476dn printer. This logic board has been fully inspected and is guaranteed to be stable and operational.
The DC Controller coordinates all internal engine operations, paper timing, and low/high voltage sequencing. If your printer is locking up, failing to boot past the initial splash screen, displaying cryptic 50.xx/79.xx firmware errors, or losing communication with components despite a good power supply, replacing this board is the definitive fix.
Key Features & Details
Tested & Working: Safely removed from a functioning machine and verified responsive.
Genuine OEM Part: Original HP internal assembly component stamped RM2-8028 / RM1-8030, ensuring accurate sensor timing calibrations and firmware compatibility.
Condition: Clean board with all multi-pin rib ribbon connectors and edge terminal pins intact.
Compatibility
This DC controller fits multiple models across this shared engine architecture, including:
HP Color LaserJet Pro MFP M476dn / M476nw / M476dw

HP LaserJet Pro 300/400 Color MFP M375nw / M475dn / M475dw
Tech Note: When installing a replacement DC controller board, ensure the printer is completely unplugged.
