Epson ET-3850 Wi-Fi Card Compatibility: Understanding the J26H006.B05 and Replacement Options

Customer Question:
I’ve been looking on your site for the vertical Wi-Fi card (model J26H006.B05) that fits the Epson ET-3850. I saw you make direct replacements for this model, but I haven’t been able to find any in stock. Do you know when these cards will be available again? And what is the price for one?

Answer:

First, let’s clarify the batch number “J26H006.B05.” That B05 designation is simply a batch or production code, not a specific model or variation that affects compatibility. It often confuses users into thinking they need to match this exact code, but that is not the case. Our replacement cards are designed to be functionally equivalent across multiple batch codes, including the “B” and “C” series, so there's no need to worry about a perfect match with the B05 version.

You can see this demonstrated in the third product image on the page for our 4-Pin Vertical Wi-Fi Card Replacement Module for Epson (https://bchtechnologies.com/products/4-pin-vertical-connect-epson-wifi-j26h006-gp-11n-bt-combo-wireless-lan-mini-usb-module-ecotank-et-2700-series-expression-premium-xp-series?_pos=2&_sid=fa0518887&_ss=r). That module works with many Epson EcoTank and Expression Premium models, including the ET-3850.

Regarding pricing and availability, although I cannot provide live inventory updates in this message, you can check the product listing directly on our site or sign up to be notified when it’s restocked. If it's currently listed, that means we have some units available. If not, rest assured that we do restock in batches regularly.

Please note that we focus on the technical compatibility of the connector interface (which in this case is the 4-pin vertical type), not the batch suffix like B05, B02, or C01.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we're unable 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. Therefore, it may take a few weeks before we can arrange for your printer to drop it off. Our services are structured to repair either the 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 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 the most efficient approach. Additionally, YouTube may suggest relevant videos from other channels that can assist you.

Thank you again for reaching out to us—we truly appreciate your continued support and involvement in the BCH Technologies community.
