Printer Too Noisy Fixing HP M402d & Restoring Auto Duplex
🔧 Fixing HP LaserJet Pro M402d – Loud Noise & Duplex Printing Issue
In this video, I repair an *HP LaserJet Pro M402d* printer sent to me by a customer. The printer has two major issues:
✅ *Loud noise when printing*
✅ *Automatic duplex printing not working* (because the duplex clutch was removed)
🔹 I will *disassemble the printer**, **replace the worn-out intermediate gears* in the fuser unit, and **install a new duplex clutch**. After the repair, the printer will run smoothly with reduced noise and fully restored duplex printing!
