Replacement Duplexer Feeding Gear (DFG) for Epson ET-8550 ET8550 Duplxer
$12.99 $19.99
This Duplexer Feeding Gear (DFG) is a newly developed non-OEM replacement for the outer section of the Spur Gear Duplex in the duplex unit. As the critical component responsible for driving the entire duplex system, the DFG connects to the drive shaft of the intermediate roller, ensuring seamless rotation and efficient paper feeding. Due to its pivotal role, this gear is subject to wear and tear and may frequently break under heavy usage-making a reliable replacement essential.
How It Works:
Power Transmission: The DFG gear receives power indirectly through a complex series of gears, beginning with the sun gear that drives the inner (larger) gear of the Spur Gear Duplex.
Drive Shaft Connection: Once the inner gear is powered, it transfers rotation to the DFG, which then powers the drive shaft of the intermediate roller.
Duplex System Operation: As the key driver of the duplex unit, the DFG gear enables the intermediate roller to rotate in sync with the paper feed mechanism, allowing paper to reverse and reposition smoothly for double-sided printing.
Features:
Precision Fit: Compatible with Epson ET-8500/L8160 and ET-8550/L8180 series printers.
High Durability: Built from robust materials to withstand the frequent stress of powering the duplex system, reducing the risk of breakage.
Enhanced Design: Designed to prevent common issues found in OEM gears, providing longer service life and improved reliability for high-demand duplex printing.
Installation Advice:
The DFG gear should be carefully aligned with both the inner gear of the Spur Gear Duplex and the drive shaft of the intermediate roller. Proper installation ensures effective power transfer and optimal performance of the duplex unit. Regular inspection of the gear can help catch early signs of wear, especially in high-use environments.
Compatibility:
Models Supported: Epson ET-8500/L8160 and ET-8550/L8180 series.
Location: Spur Gear Duplex, as the external gear in the duplex transmission system.
Why Choose This Replacement DFG Gear?
The DFG gear is essential for maintaining duplex functionality, ensuring smooth and consistent paper handling. This durable replacement part is designed to withstand the demands of frequent duplexing, providing a cost-effective solution to common gear breakage issues and extending the overall lifespan of the duplex unit.

Worked perfectly Followed video instructions and refilled the cartridge successfully. I skipped the cleaning part which meant there was some dried ink causing print issues. I went back and soaked the cartridge in warm water like suggested, now it prints perfectly!
