Customer Question:

Will this Epson power supply work with the ET-4850 printer? Also, is it a 24V DC unit?

Referring to this product:
Epson Power Supply for ET-4750, ET-15000 (No Return)

Answer:

Clarifying the Power Supply Compatibility for the Epson ET-4850

To address your question directly:

The Epson ET-4850 uses a 3-prong power supply connector. In contrast, the power supply linked in your question—which is designed for the ET-4750 and ET-15000 models—uses a 2-prong connector. These two configurations are not physically compatible, and attempting to use an incorrect power supply could result in electrical damage or complete failure to power the device.

Additionally, regarding the voltage:
Epson printers like the ET-4850, ET-4750, and similar models do not use 24V DC power supplies. Instead, they are built to operate with a 42V DC power supply. This voltage standard is consistent across most mid-range and high-end Epson EcoTank printers.

In summary:

• ET-4850 power supply connector: 3-prong

• Linked power supply: 2-prong — not compatible

• Voltage: Epson uses 42V DC, not 24V DC

• Result: The power supply in question is not suitable for your ET-4850.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, 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. So, it might take a few weeks before we can get your printer to drop it off. Our services are structured to repair either 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.

Thanks again for reaching out and trusting us with your technical questions. Your continued support means the world to us, and we hope this information helps you move forward with your printer repair or upgrade journey.
