Resolving Connection Issues on Epson L1800 DTF Printer with Replaced Mainboard

Question:
My Epson L1800 DTF printer main board got shot, and I replaced it recently. The printer powered up typically but printed a test page, and nothing happened. When I checked the printer settings on my computer, the printer address said "not connected." I confirmed that the USB cable is plugged into the printer and computer. Is this normal, or is there another step I need to take?

A mainboard replacement in a printer essentially makes that printer "new" to your computer, and there can be a few potential hurdles. Now let's run through how to troubleshoot and solve the issue correctly:
 
Check Physical Connections
Certain modified printers, like the Epson L1800 DTF, frequently have a USB link diverted to the printer’s external shell for access. 1. Connect this external USB cable to the new mainboard. An incorrectly connected or loose cable might not recognize the printer in the PC.
 
Reinstall Printer Drivers
Because the mainboard replacement alters the printer's identity, your computer may consider it a new device. Printers can be connected to the computer automatically, and their corresponding drivers are usually installed automatically. Still, this process succeeds only partially or fails altogether in many cases, requiring manual intervention.
Reinstall the latest drivers for your model from Epson’s official website.
Again, please follow the installation instructions, making sure the printer is connected while doing so.
 
Verify and Modify the Port Configuration
A replaced mainboard typically registers the printer with your computer under a new port number. This can block your software from contacting the printer.

  • Please check the setup program (if available for your model) to see what port number your printer uses.
  • In your RIP (Raster Image Processor) software, please update the port to match the new port number. This process ensures that the software issues its commands to the correct port.

Try a Different Cable or Port
Disconnecting these devices can sometimes fix USB connection issues. Other causes could be failed USB cables or computer USB ports. Try switching cables or plugging it into a different USB port, just in case.
After performing all these steps, your Epson L1800 should reconnect successfully so that you can continue printing.
 
It's a hands-on problem type, so addressing printer issues is a mess. We’re sorry, but we cannot provide remote troubleshooting, advice, or support for printer repairs. We cannot offer a physical exchange (other than a third party). However, we have a local diagnostic (https://bchtechnologies.com/printer-repair-service), but due to the volume of requests, we take them first come, first serve, and it could be a while before your printer gets dropped off.
We repair complete printers or parts with clear instructions on how to help. Our rates might not be the best in the industry, and we always recommend that you check out self-help as well, look for videos on our YouTube page (https://youtube.com/@bchtechnologies) or search for specific topics using the search box.
Thank you again for your inquiry and your support of BCH Technologies. We’re here to help. Please reach out again if you have more questions!
