Question:
The printer is a DTG L805, and the mainboard got shorted out due to an ink spill. While some functions are working after replacing the mainboard, I have another strange problem: My printer remained stuck with the paper light on. Does this new board require any software to be loaded on? Do you have any guides or resources that could help troubleshoot this issue? I’m tech-savvy, but I can’t find anything on this, and nothing is labeled. Any advice on this would be much appreciated. Thank you!

I appreciate your reaching out and am sorry for the long reply. I fully relate to your frustration with a non-functional printer and am always trying to be general and specific. You make it possible to continue this work, and we are all so grateful for your support, especially our channel on YouTube, https://youtube.com/@bchtechnologies. Your involvement allows us to improve our technical skills, and it's always lovely to hear that we're doing something good for users like you!
For example, you encountered an "Epson L805 paper light problem after mainboard replacement." That could mean a few things, but let’s examine the most likely causes and how to resolve them.
First, the answer is whether the new board needs software is that the mainboard may need some software installed or configured correctly. Some printers, including many Epson models, particularly the L805, require specific firmware and software configurations to function correctly. Without these features, some functionalities may not behave as intended, for example have sensors like the paper feed sensor. Check if there was pre-installed software when you purchased the mainboard or if you need to download and install the appropriate firmware for your model. The firmware will sometimes completely change the way your printer behaves.
Now, about the paper light is on: This can indicate several things. In cases where the board was previously shorted out, that short may have damaged the sensors or wiring near the paper feed. The bulk of the troubleshooting of this problem is figuring out if it is the new mainboard or a problem with the control panel wiring.
You’ll want to check one important detail: whether or not your control panel has been rewired to the OEM control panel. Epson printers have different error light patterns depending on configuration, and some models, like yours, might have had the control panel rewired. This makes interpreting error codes and light signals more challenging. The paper light pattern on an OEM control panel may indicate a different fault than one custom-rewired.
To help you with installation, troubleshooting, and other repairs, you can check our website and search for the L805. We have repair references and guides to help you understand these problems. The step-by-step instructions should clarify things and walk you through fixing the error. Please check out our site, BCH Technologies—L805 Repair Resources.
We cannot provide remote troubleshooting or printer repair support because printer issues are somewhat involved, especially in electromechanics and wiring. Our local diagnostic facility offers in-person evaluation and repair service, details of which can be found on our printer repair service page. Since this tends to be first come, first served, please remember that it may take a couple of weeks before we can get your printer in for service.
We offer the repair of the entire printer or parts and will guide you on the next moves. That's very true, but our rates aren't the most affordable. You should always seriously consider resolving the issues yourself through online self-help! You can start by checking out our YouTube channel, which has many great troubleshooting videos that may address problems like yours.
