Fix Epson ET-8550 Not Booting Up After DTF Upgrade

Question:
I recently converted my Epson ET-8550 printer to DTF, and it keeps turning on and off. The control panel comes on, but the printer doesn’t start doing its checks. What is wrong, and how do I fix it?
 
Answer:
Thank you for your question. I am very sorry for the late response. I know how urgent and annoying printer problems can get, especially when they break your flow. I want to ensure your concerns get the attention they deserve and are answered thoroughly. We at BCH Technologies appreciate your continued engagement and support, especially on our YouTube channel (https://youtube.com/@bchtechnologies). Even though it is very late now, your response allows us to polish our technical insights and broaden our horizons.
 
As for your Epson ET-8550 printer problem:
Judging from your video, the control panel is usually turning on. At this point, the printer typically starts its boot sequence, where it runs a test of all the components before entirely booting. But in your case, the process stops short, and the printer simply cycles on and off repeatedly. Based on these symptoms, the most probable cause is a firmware malfunction at the printer's end.
 
Understanding the Problem
Firmware is the essential software that enables the printer’s hardware components to communicate with each other. The printer will not complete its boot-up process if the firmware file is corrupt (this can happen during conversions, such as DTF changes). Unfortunately, if the printer cannot fully boot, it also cannot accept a firmware update through conventional means, which leaves it in this endless loop.
 
Possible Solutions

• Professional Firmware Recovery: To fix this problem, you’ll probably need the help of a professional repair service. They have the specialized hardware to flash the printer’s firmware directly to the mainboard. It requires physically getting into the device and using proprietary hardware and software to flash the firmware.
• Warranty Options: If your printer is still under warranty, contact EPSON Support (https://epson.com/support) to initiate a warranty claim. Make sure you explain the problem and how recently you made any modifications, as that could affect warranty coverage.
• Preventive Measures After Conversion For upcoming conversions, whether for DTF or similar processes, I suggest that you install all of the latest firmware and drivers prior to any undertaking like this. Following the conversion instructions to the letter also reduces the risk of firmware-related troubles.

Additional Note
Printer problems are challenging to troubleshoot because they are very hands-on in nature. So, we cannot do, you know, remote troubleshooting, suggestions, support for printer repairs. We also have a local diagnostic facility where we provide an in-person diagnostic and repair service (https://bchtechnologies.com/printer-repair-service). But keep in mind, due to the sheer volume of submissions, our storefronts work on a first-come, first-served basis, so it can take several weeks before you can leave your printer with us. We offer full printer or individual part repairs and outline a simple how-to-go-about-it. That said, we also understand that our repair rates may not be feasible for everyone. As such, we also recommend self-help via online research.
