Inkjet Printers: The great invention of Epson TFP print head

Epson F-series printer is adopting exclusive PrecisionCore™ TFP® print head technology which is a great impetus to the printing quality.It would be extremely difficult for another company to replicate Epson's PrecisionCore printheads.

That is because only Epson owns the innovative technologies that are essential for the manufacture and assembly of Micro TFP print chips, the heart of our Precision Core printheads.

A TFP actuator is an extremely thin piezo element formed on a silicon substrate. The piezo element contracts when a voltage is applied to it. This movement provides the power to drive ink, which flows into the ink flow path, from the nozzle plate.

Thin film piezo technology is used to form piezo elements on a silicon wafer in uniform, one-micrometer-thick films. High-quality ceramic crystals that have consistent orientation are formed by sintering using Epson's own crystallization process.

These TFP actuators provide extremely precise control over droplet size and placement and astonishingly accurate prints. That is because their uniform crystal structure means that they maintain uniform displacement when they contract and because the extreme thinness of the piezo film allows for larger contractions and, thus, larger displacement.
