Can a Procolored F13 Use an Epson L1800 Mainboard with Ethernet?

Question

I own a Procolored F13, and I understand that its internal printer platform may be based on the Epson L1800. I do not think Procolored used custom firmware, but one of the boards in my machine only has a USB printer port. Is it possible to replace that board with an L1800 board that has Ethernet, and would it be plug-and-play?

Answer

The short answer is: before assuming your Procolored F13 is based on an Epson L1800, I would first verify whether the internal printer is actually closer to an Epson 1390/1400-style platform. Many DTF and UV printer manufacturers use Epson-based mechanics, but the advertised model or outside branding does not always tell you exactly which internal Epson platform is being used.

In your case, my first guess would actually be that the printer may be based on an Epson 1390 platform rather than a true L1800. There are a few ways to check.

One practical way is to look at the carriage assembly. If the CR carriage is full width and wide enough to accept a cartridge-style assembly, that is often a sign that it is a 1390-style setup. The carriage layout can give you a clue because the 1390 and L1800 platforms may look similar from a distance, but there are differences in carriage design, cabling, and board configuration.

Another way is to inspect the mainboard number. If your mainboard is marked C655 MAIN, then you are likely dealing with a 1390-style board. If the board is marked CB53, then you need to look more closely at connector CN22. If CN22 is mounted with a full socket, that usually points toward a 1390-style configuration. If the board is CB53 and nothing is mounted at CN22, then it is more likely to be an L1800-style board.

This distinction matters because, while the L1800 and 1390 families are related in many ways, they are not always safely interchangeable in real-world converted printers. Even when connectors appear similar, the firmware, sensor expectations, carriage behavior, motor control, paper-feed logic, and error handling may not match perfectly. A board can physically fit and still create strange problems.

In general, yes, it is possible to replace a damaged mainboard with another compatible mainboard, but I would be careful about mixing an L1800 board into a 1390-based printer. From experience, using an L1800 board in a 1390-style printer can lead to many odd errors. These may include carriage movement errors, sensor errors, communication errors, initialization failures, or other behavior where the printer powers on but does not complete its startup sequence correctly.

The main issue is that the printer is not just a collection of plugs. The mainboard expects a specific hardware environment. It is looking for certain sensors, cables, carriage behavior, encoder feedback, motor responses, and sometimes a specific control-panel or sub-board configuration. If one of those expectations does not match, the printer may stop with an error even though the board technically powers on.

For example, if the board expects one type of carriage or sensor configuration but the printer has another, the machine may fail during initialization. If the board expects a different paper-feed or ASF behavior, it may produce feed-related errors. If the encoder strip, CR motor, PF motor, or sensor wiring does not match the board's expectations, the printer can also throw general communication or mechanical errors.

Regarding Ethernet, I do not recall the standard Epson L1800 mainboard commonly being an Ethernet-equipped board. The L1800 is generally known as a USB-connected printer platform. Some related Epson models or third-party control setups may have network options, but I would not assume that an "L1800 board with Ethernet" will be a simple plug-and-play upgrade for your Procolored F13.

Even if you find a board with an Ethernet port, that does not automatically mean it will work with your printer body. The firmware and board layout still need to match the mechanical platform. Network capability is only one part of the board. The more important question is whether that board correctly supports your carriage, sensors, motors, ink system, and any modifications Procolored made for the F13.

If your goal is simply to add Ethernet or Wi-Fi printing capability, I would not replace the printer's mainboard just for that purpose. A much safer and easier option is to use a USB print server. A USB print server allows a USB-only printer to be shared over Ethernet or Wi-Fi, depending on the print server model. In that setup, the printer still uses its original USB interface, but the USB print server acts as a network bridge.

That approach is usually much less risky than changing the mainboard. Replacing the board could introduce compatibility issues, while a USB print server leaves the printer's original electronics intact. However, with DTF printers, RIP software, and converted Epson platforms, you still need to make sure the print server supports the type of USB communication your software requires. Some RIP programs or printer utilities work best with a direct USB connection, so you may need to test carefully.

If your original board is defective, another option is to repair the existing mainboard instead of replacing it with a questionable substitute. We do offer mainboard repair services, and that can sometimes be the better route if the printer was working correctly before the board failed. Repairing the original board keeps the printer's configuration the same and avoids the risk of introducing a mismatched board.

So, my recommendation would be:

First, identify whether your printer is actually based on the 1390 or L1800 platform. Check the carriage width, the mainboard marking, and the CN22 connector area if the board is marked CB53. If it is a 1390-style printer, I would avoid installing an L1800 board, because it may create many errors. If the board is truly L1800-based, then replacing it with a matching L1800 board may be possible, but I still would not assume Ethernet compatibility unless the board, firmware, and printer configuration are confirmed to match.

Second, if the only reason for the board swap is to add Ethernet, I would use a USB print server instead. That is usually the cleaner solution. It gives you network access without disturbing the printer's internal electronics.

Third, if your current board is damaged, consider repairing the original board or replacing it with the exact same board type. Matching the board model is far safer than trying to upgrade to a different platform.

Addressing printer issues can be a complicated affair because many of these problems require hands-on inspection. For that reason, we are not able to provide remote troubleshooting, remote diagnosis, or step-by-step repair support for printer repairs. We do offer an in-person evaluation and repair service through our local diagnostic facility, BCH Technologies Printer Repair Service [https://bchtechnologies.com/printer-repair-service]. Because demand is high, we operate on a first-come, first-served basis, so it may take a few weeks before we can accept your printer for drop-off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. However, we understand that our rates may not be the most economical option for every situation. For that reason, we highly recommend starting with self-help and online research. You can begin by checking YouTube or visiting our channel homepage, BCH Technologies on YouTube [https://youtube.com/@bchtechnologies]. Use the search icon next to "About" on the right-hand side of the menu bar to look for specific videos. I receive dozens of questions every day asking for videos on specific topics, and after creating videos for more than nine years, it is difficult to remember every single one. YouTube's search function is usually the fastest way to find the most relevant video, and it may also suggest helpful videos from other channels.

Thank you again for reaching out and for supporting BCH Technologies. I hope this helps you avoid an unnecessary board swap and gives you a safer path for adding network printing or repairing the existing board.
