The benefits of Heat-Free Technology

Ink ejection technology that determines productivity, print quality, and environmental performance

Epson's proprietary Micro Piezo inkjet technology doesn't use heat in the ink ejection process, and it's this Heat-Free Technology that separates our printers from the competition. This Heat-Free Technology serves as a common platform for all Epson inkjet printers, whether for the home or office.

This core technology allows Epson's inkjet printers to deliver productivity and print quality equal to that of laser printers, which currently dominate the office market. They also help to reduce users' TCO* and environmental impact.

Comparison with laser technology

The laser printing process is complicated, comprising of preheat, charging, exposure, development, transfer, and fusing steps. Fine toner powder is transferred to a sheet of paper through contact and fused with a combination of heat and pressure.

In contrast, Epson's piezo inkjet printers are simple, non-contact systems. They deposit ink droplets on media without heating the ink, so they are durable, require only infrequent parts replacements, and generate little waste. Even if paper does jam, it can be removed easily and safely because there are no hot parts. The fact that they do not use heat also means that they use less power.

Comparison with other inkjet technologies

The thermal inkjet systems used by most other printer companies need to heat the ink to boiling to fire it through the printhead. They then need to wait for the ink to cool to a certain temperature before they can print again. This need to wait means that printing speeds can fall sharply especially when continuously printing high-density patterns that use a lot of ink because the printheads are continuously heated and need time to cool down.

On the other hand, Epson's Heat-Free Technology prints via the action of piezoelectric actuators, which mechanically eject droplets of ink as they flex back and forth under an applied voltage (piezo displacement), so they are able to maintain consistent high speed even when printing high-density patterns.
