Torsion Spring for Timing Belt (CR Encoder Scale) - Epson WF-7720 WF-7710

Yes, you can easily make your own with a washed out water bottle but these come ready to go and are a better quality plastic. I won’t be using mine as a waste tank since I have a my CISS but will be using the bottle for my maintenance and cleaning solutions.

I can’t say enough about this company! Sent my main board in for repair and they were fast and the cost was reasonable. They are also quick to respond. This is not the first item I’ve purchased from them and won’t be the last. Also, the YouTube videos are a must to watch!

I have an old Epson ET-2750 eco tank printer, which I have used for years, and since it is uses refillable ink tanks, have used very little ink over the years. I love this printer because I can print lots and lots of pages, including double-sided at very low cost, and it is very reliable. I recently had a paper jam, which is very unusual. When I took off the back panel to clear the jam, I accidentally dropped it on the floor, and when I replaced the back panel, the printer jammed every time I tried to print double-sided. I found a small plastic piece on the floor that fit on one end of the roller, but didn't realize I was missing the other end. I eventually noticed that there was a gear on the back panel next to where the roller fits into the panel. I deduced that I must be missing a gear to pop into the end of the roller, to mesh with the gear on the panel. I couldn't find the missing gear anywhere, and figured my cats must have lost it or my wife might have swept it up when sweeping the floor, and discarded it. Through a Google search, I found BCH Technologies, ordered the part from them, it fit perfectly, and now I can print double-sided again on my faithful old Epson printer. I very much appreciated being able to get the missing part from them. I thought the price for the part and shipping was high for such a small part, but that was the only down side.
