Troubleshooting and Identifying Printhead Connection Boards for the Enjoycolor 3A+R DTF Printer

Question: Do You Have the Board for My Enjoycolor 3A+R DTF Printer and How Can I Test It?

Attached are photos of the board and its location on the printer. I need to know if you have this board. Also, how can I test the board to see if it's my problem? The data strip is a 9-pin 15cm on both the board end and the printhead end. Does this mean I have an L1800 printhead?

Answer:

Thank you for contacting us at BCH Technologies. We are grateful for your engagement and support, particularly with our YouTube channel [https://youtube.com/@bchtechnologies]. Your feedback plays a crucial role in further developing our technical expertise.

The board you are referring to converts an L1800 printhead connection to an L805 connection. This indicates that your printer uses an L1800 printhead, but the manufacturer has converted it to use an L805 printhead, which is generally cheaper.

If you have an L1800 printhead, you can remove this conversion board and connect the cables directly to the L1800 printhead. We do have this board available, and it will be put on sale shortly. However, it is important to note that the board might not be the root cause of your problem.

To test if the board is causing the issue, follow these steps:

1. Check Connections: Ensure all cables and connections to the board are secure and free from damage.
2. Inspect for Damage: Look for any visible signs of damage on the board, such as burnt components or broken traces.
3. Use a Multimeter: Test the continuity of the connections using a multimeter to ensure that the signals are passing through correctly.
4. Swap Components: If possible, swap the board with a known working one to see if the issue persists. This can help determine if the board is faulty.
5. Firmware and Software: Ensure that the printer's firmware and any related software are up-to-date, as sometimes issues can be related to software rather than hardware.

If after these steps you determine that the board is functioning correctly, the issue might lie elsewhere. Common problems include faulty printheads, issues with the mainboard, or problems with other components in the printer's electronics.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. For instance, resolving a simple clog might involve advice on unclogging procedures. However, if the printer remained inactive during downtime, a comprehensive service for the ink system could be necessary. Situations like a "paper jam" can arise from hundreds of potential causes, and solving such an issue has become something of an in-office jest. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility [https://bchtechnologies.com/printer-repair-service]. Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks before we can get your printer to drop it off or mail it to us. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed if you opt for mail-in or local drop-off services. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage [https://youtube.com/@bchtechnologies]. Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thank you again for reaching out to us. We appreciate your interest and support.
