Question:
The new mainboard I got for my Epson L1800 printer is incompatible with my power supply connector, which is not the same as my present power supply. So, what should I do with the L1800 mainboard?
Answer:
Thanks for your inquiry and question about the mainboard power supply of Epson L1800. Sorry I have taken so long to write to you. These types of printer hardware issues are always urgent, and I want to make sure we do it right. At BCH Technologies, we appreciate your support—especially via our YouTube channel (https://youtube.com/@bchtechnologies).

Well, here’s your concern well-addressed.
The Power Supply Issue Explained
Your existing power supply is a third-party power supply designed for the old version of 1390 mainboard (C655). It also requires a power supply with more pins than the usual L1800 (CB53) or the new version1390 (also CB53) mainboard connectors. The L1800 mainboard could be used in a 1390 printer if its power supply was 3-pin. Or, you simply get an OEM 3-pin power supply.
Recommended Solutions
Install an L1800-Compatible Power Supply:
- The easiest solution is to swap it out with a power supply for the L1800. For your safety and reliability, we suggest installing an OEM L1800 power supply.
- You can purchase a compatible power supply from BCH Technologies, such as the Epson EPS-135 Power Supply if you use 110v power: (https://bchtechnologies.com/products/epson-eps-135-power-supply-for-l-1800-1430-1400-1390-r2000-no-return).
- The EPS-135 only supports 110V input power. In most parts of the world (including Europe), the primary supply voltage is 220V, so make sure you purchase a power supply that is 110/220V compatible.
- Using the wrong authorized voltage will damage the power supply and the mainboard.
- Though third-party power supplies might be more convenient, they can be of poorer quality or less reliable than OEM parts. This can cause performance issues, which can be the reason for some mainboard damage in the future.
The 1390 and the L1800 printers have two versions of mainboards, and the power supply is not that compatible. Confirm the version of the mainboard you’re buying to ensure a seamless setup.
Why OEM Parts Are Recommended
OEM (Original Equipment Manufacturer) parts are the same as those created especially for your printer. OEM power supplies are designed to maintain the exact voltage and consistent operation while minimizing hardware failure.
