Restore smooth drive train transmission and eliminate gear grinding errors with this Import-Grade Belt Drive Gear for HP LaserJet Pro M202 and M226 series printers. In HP’s desktop monochrome printer architecture, the main drive motor uses a combination of precision gear trains and drive belts to distribute mechanical power across the paper pickup, registration assembly, toner cartridge drive, and fuser unit simultaneously.
Mechanical Wear & Operational Failure Modes:
Over high page print volumes or following sudden paper jam clear attempts:
- Tooth Stripping & Wear: Plastic gear teeth undergo high friction stress, resulting in worn-down, chipped, or completely sheared teeth along the belt-drive engagement surface.
- Axis Spline Cracking: Heavy load friction can cause the central mounting core to crack or expand, causing the gear to spin freely on its shaft without turning the drive belt.
- Drive Slippage & Noise: Stripped teeth cause the drive motor to slip under load, resulting in loud clicking or metallic gear grinding sounds during initial warmup or page printing.
Key Symptoms Solved:
- Loud Grinding / Chattering Noise: High-pitched chatter or gear slipping sounds coming from the main motor side frame during engine startup.
- Drive Train Paper Jams: Paper stops abruptly before entering the fuser due to lost drive power transmission.
- Main Drive Motor Lockup: The main motor spins, but paper transport components remain completely static.
- Missing Print Engine Motion: The printer initializes electrically, but the mechanical drive fails to cycle properly.
Manufactured with high-density polyoxymethylene (POM / Acetal) industrial plastic, this precision molded replacement gear provides low friction, heat resistance, and precise tooth engagement for long operational life.
