Epson EcoTank ET-2750 ST-2000 Mainboard - CG22 Main-B - Logic Formatter Motherboard Mainboard
$59.99
The mainboard offered here is compatible with both the Epson ST-2000 (the corporate version of the EcoTank ET-2750) and the ET-2750 model. Essentially, the ST-2000 and ET-2750 are identical. Upon connection to a computer, they can be identified as either the ST-2000 or the ET-2750. You can download suitable drivers for these models from the Epson website.
EXAMPLE. If you have an ET-2750 printer with a malfunctioning mainboard and replace it with the one in this listing, the system may recognize it as an ST-2000. In such a case, you'll need to visit Epson.com to download the ST-2000 drivers, after which your printer should be good to go (your printer will be a ST-2000 from now on).

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.
