Original Power Supply Board for HP LaserJet Pro MFP M126nw / M128fn / M128fw — Imported

Get your HP LaserJet Pro MFP back to life with the PRM Original Power Supply Board. This is a genuine original board — not a compatible copy — sourced from original equipment and imported directly. One board fits the entire M126/M128 series.

Looking for an HP M126nw power supply or HP M128fn power board? This is the correct power supply board for the entire M126/M128 range.

When Do You Need a New Power Supply Board?
The power supply board converts mains AC power into the regulated DC voltages that run every component inside your printer — the formatter, fuser, motor, scanner, and WiFi module. When it fails, the entire printer is affected. Replace your power supply when you see:
- Printer completely dead — no lights, no display, no response when pressing the power button
- Printer turns on briefly then shuts off immediately
- Random shutdowns during printing — printer dies mid-job
- Fuser error messages — the power supply feeds the fuser heater; a weak supply causes temperature errors
- Burning smell from the power supply area (not from the fuser)
- Printer takes unusually long to warm up or never reaches ready state
- WiFi module not powering on — printer drops off the wireless network (M126nw / M128fw)
- Flickering display or lights dimming during printing
- Scanner lamp not turning on during scan/copy
- Tripping your office power switch when the printer turns on

If you've checked the power cable, tried a different wall socket, and the printer still won't power on or keeps shutting down — the power supply board is almost certainly the cause.

1. One Board Fits the Entire M126/M128 Range: This power supply board is compatible across the HP LaserJet Pro MFP M126a, M126nw, M128fn, and M128fw. Same board, same connectors — works in all models whether USB-only, WiFi, or fax.

2. Original, Not Compatible: This is a genuine original HP power supply board — the same board that came inside your printer from the factory. Original boards offer exact voltage regulation and long-term reliability that compatible copies cannot match. For a critical component like the power supply that feeds every part of your printer, original is the right choice.

3. Fixes the "Dead Printer" Problem: The most common power supply failure symptom is a completely dead printer — no lights, no response. Before you discard a perfectly good printer, a power supply replacement brings it back to life for a fraction of the cost of a new printer.

4. Resolves Fuser Errors Without Replacing the Fuser: Many fuser errors on the M126/M128 are actually power supply problems — the board can't deliver enough power to heat the fuser properly. If you've already replaced the fuser and still get temperature errors, the power supply is the fix.

5. Restores WiFi and All MFP Functions: The power supply feeds every component — formatter, fuser, motor, scanner, WiFi module. A failing supply can cause seemingly unrelated problems across print, scan, copy, fax, and wireless connectivity. A new board restores stable power to everything.

6. Easy Installation: Disconnect the printer from mains power, remove the side/rear panels, unplug the connectors from the old power supply board, swap in the new one, reconnect all cables, and reassemble. 20-30 minutes for any printer technician. Basic screwdriver needed.

7. Tested Before Shipping: Every PRM power supply board is tested for correct voltage output before dispatch. Backed by our testing warranty.
