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.

Great products for maintaining a dtf machine. The filters are too small for my xp600 machine All the products are good, some are too small for my needs but that's my fault. Filters are too small for my A1 dtf machine. I can still use the syringes but I really needed larger capacity to be efficient maintaining my commercial machine. Quick shipping, products are always quality and packaged very well. I've learned so much from all of the videos. Thank you!

Huge money and time saver!! I've been refilling my cartridges for a long time, but with my daughter becoming a teacher, printing has grown exponentially. After lots of research and pondering options, I decided to go with the Spongeless kit. I watched the YouTube videos several times before doing the conversion. It's not an easy process and requires patience, but it was the best decision ever! After the conversion, we were able to print about 300 pages without any issues, and the refilling process was super easy. Highly recommended if you have the patience and skills.

I'm such a happy customer thank you! Finally!! Beautiful prints from ink I installed on my own! As someone who recently ditched HP after years of paying for a subscription I had enough of over charging and the control of the company over a printer I bought! So I bought a Canon just to have issues with ink suppliers. And then i.found Kevin's YouTube and my confidence grew that i.could buy this kit and refill my own ink! It came so nicely packaged yesterday and within 40 min, I reviewed the video 🤪, I was printing! Now I want to go sponge less! You can't lose by buying this kit, and Kevin is a phenomenal teacher! Thank you so much it only took til 46 yrs old to learn!
