There are two main printhead technologies commonly used in inkjet printers:
Thermal Printheads:
Thermal printheads use tiny heating elements to rapidly heat the ink, creating vapor bubbles that expand and force ink droplets onto the paper. This technology is commonly found in consumer inkjet printers, such as those from HP and Canon.
Piezoelectric Printheads:
Piezoelectric printheads utilize piezoelectric crystals that change shape when subjected to an electric current, precisely ejecting ink droplets without requiring heat.
Micro Piezo is a proprietary piezoelectric inkjet technology developed by Epson.
Epson primarily uses piezoelectric technology in its printers, including consumer, professional, and industrial models. Some high-end models feature PrecisionCore, an advanced variation of piezoelectric technology that enhances speed and accuracy.
Piezoelectric Applications:
Found in lighters, igniters, transformers, microphones, filters, sensors, inkjet printheads, and medical devices.
Fun Fact: Did you know that the word Piezo comes from the Greek word piezein, meaning "to press" or "to apply pressure"?
