How to Convert an Epson EcoTank to a Sublimation Printer (Which Models Actually Work)
Last Updated:
Quick answer: Converting an EcoTank means draining or bypassing Epson's own ink and refilling the tanks with third-party dye-sublimation ink. It works because EcoTank printers use a piezoelectric print head that doesn't need to heat the ink, but it means using ink Epson didn't design the printer for, so it's worth understanding the tradeoffs before you start.
Which EcoTank Models Are Commonly Converted
Small shops most often convert the Epson EcoTank ET-2800 and similar ET-2760/ET-2803-series models because they're inexpensive, widely available, and use the same four-tank ink layout. We reviewed the ET-2803 specifically in our honest EcoTank ET-2803 review, which covers print quality and running costs before you decide whether to convert one.
How the Conversion Works
In practice, most sellers either flush the factory ink completely and refill with sublimation ink, or buy a printer new and fill it with sublimation ink from the very first setup so the two inks never mix. A ready-made sublimation ink set, such as Hiipoo sublimation ink for EcoTank printers, is formulated to run through the same piezo heads without clogging, paired with sublimation paper and a heat press to finish the transfer.
The Warranty Question
This is the part sellers most often ask about, and the honest answer is: using non-Epson ink is generally outside what Epson's standard printer warranty is designed to cover, since the warranty assumes Epson-branded ink. Epson doesn't market EcoTank printers as sublimation devices, so we'd recommend checking the current warranty terms on Epson's EcoTank product page for your specific model before converting, rather than relying on general internet advice (including ours). Many small shops decide the cost savings are worth accepting that risk, since a converted EcoTank is a fraction of the price of a dedicated sublimation printer.
Is Converting Worth It, or Should You Buy Sublimation-Ready?
If you'd rather skip the warranty question entirely, our guide to the best sublimation printers for small businesses covers ready-made options like the Epson SureColor F170 and Sawgrass SG500 that come sublimation-ready with no conversion needed.
