How to Send Your Epson ET-8550 Mainboard for Repair After Error 031006

Question:
I watched your video about replacing F1 and F2 fuses on the Epson ET-8550 to fix the Error 031006 issue. I'd like to send my ET-8550 mainboard in for repair. How should I contact your company to let you know that I'm sending it?

Answer:

Now, regarding your question-there's actually no need to contact us directly before sending your mainboard. We've made the process simple and streamlined. You can go straight to our Fast-Track Mainboard Repair Service page at BCH Technologies Mainboard Repair Service (https://bchtechnologies.com/collections/printer-repair-service/products/fast-track-mainboard-repair-l1800-xp-15000-et-15000-wf-7610-7620-wf-7110-wf-7710-7720-et-8550-et-2720-et-2750printer-mainboard-formatter-board-motherboard-troubleshooting-and-repair).

Once you place your order on that page, you'll receive all the necessary shipping information and instructions on how to send in your ET-8550 mainboard for service. After we receive your board, our technicians will perform diagnostic testing to determine the issue-often related to blown F1 or F2 fuses, which can cause the Error 031006. We'll then carry out the repair or replacement of the damaged components and test the board before returning it to you.

Many customers experience this issue after a power surge or when installing a Continuous Ink Supply System (CISS). These small fuses act as circuit protection for the power lines on the mainboard. If they are blown, the printer may display Error 031006 or even fail to power up at all. While some users can replace these fuses themselves using a fine-tip soldering iron and a compatible fuse (usually 2A-3A surface-mounted), sending it to our repair facility ensures professional-level diagnostics and repair accuracy-especially if other power management ICs are affected.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service through our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis, so there might be a short waiting period before your printer or board can be processed. Our services are structured to repair either an entire printer or specific parts, with detailed instructions on how to proceed. However, we understand that professional repair can be costly, so we also recommend trying self-help methods. You can start by visiting our YouTube channel (https://youtube.com/@bchtechnologies) and using the search icon next to "About" to look up terms like "ET-8550 fuse" or "Error 031006."

Thank you once again for your patience, and for being part of the BCH Technologies community. We truly appreciate your trust and continued support in our mission to help printer users troubleshoot and learn more effectively.
