How to Connect the BCH Micro Diaphragm Pump for DTF/DTG Printers: Understanding JST Connectors and Compatibility

Customer Question:
Does the BCH Micro Diaphragm Pump for DTF/DTG printers have connectors that allow it to be plugged directly into a printer's control board? If not, where can I find compatible 2-pin connectors?

Answer:

Now, let’s dive into your question about the Micro Diaphragm Pump for DTF/DTG printers (24V, 3W, 100–200 ml/min) [https://bch-youtube-fan-store.myshopify.com/products/micro-diaphragm-pump-for-dtf-dtg-printers-white-ink-management-system-24v-3w-100-200-ml-min].

Pump Compatibility and Connectors

The diaphragm pump does not universally come with connectors suitable for direct plug-in to every kind of mainboard. Here's the breakdown:

• If you use an OEM Epson mainboard (for example, from an L1800 or similar Epson printer), these boards typically do not provide a 24V output connector for external components like pumps. Epson’s factory boards are designed for particular internal components and often lack the flexibility to directly integrate third-party devices like our diaphragm pump.

• If you are using a third-party controller board—such as those used in DTF conversion kits—the situation might be different. The pump we supply includes a JST SM connector, a 2-pin male connector commonly used in hobby electronics and printer modifications.

  • JST SM Connectors are polarized and include a locking mechanism to prevent accidental disconnection. They are ideal for DC devices like our pump.

  • If your third-party board supports 24V outputs and includes a compatible female JST SM port, you can plug the pump in directly.

  • If your board doesn’t have the JST SM port, you may need to adapt the connection using pigtails or matching 2-pin JST connectors.

For a detailed overview of different types of JST connectors (SM, XH, PH, etc.), their pin arrangements, and how they interface with control boards, we highly recommend our comprehensive guide: Comprehensive Guide to Common JST Connector Types [https://bchtechnologies.com/blogs/news/what-are-those-connectors-called-on-a-mainboard-comprehensive-guide-to-common-jst-connector-types].

These are widely available online if you're looking to source JST connectors. Try searching for "2-pin JST SM connector male and female pair with leads" on websites like Amazon, eBay, or electronics-specific retailers like DigiKey or Mouser.

Power Supply Considerations

Please ensure your board can deliver 24V at approximately 3W (around 125mA current draw). Supplying incorrect voltage could damage the pump or reduce its efficiency.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we cannot 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. It may take a few weeks to get your printer to drop it off. Our services are structured to repair a whole printer or specific parts, with clear instructions on how to proceed. 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 once again for your interest and support. We appreciate your continued engagement and hope this information gives you a clear path forward.
