Epson Micro Piezo Technology
What is an Epson Micro Piezo print head?
“Micro Piezo” is the name of the multi award-winning, proprietary piezoelectric technology that is used in
heads of all Epson inkjet printers which has made them renowned for their high quality output and relia
well as low running cost.
Since the introduction of the technology in 1993 till today, Epson has been the only company tha
piezoelectric print head throughout its inkjet printing device range – from the smallest personal photo p
the largest industrial system.
How does an Epson Micro Piezo print head work?
To push ink out from the print nozzles, an Epson Micro Piezo inkjet print head uses what are kn
“piezoelectric” materials that bend when an electrical charge is passed through them.
Using piezoelectric technology, the amount of ink pulled into and expelled out of the nozzles can b
accurately controlled by varying the electrical charge given to the piezoelectric elements. This enables t
head to eject ink droplets in a range of precisely controlled sizes.

Resolution Epson Micro Piezo print heads allow for precisely sized drops of
ink of up to five different sizes to be ejected onto the medium,
resulting in sharper, grain-free prints with smoother tonal
transitions.

Compatibility
The low temperature operation of Epson Micro Piezo print
heads make them compatible with a wide range of inks,
including dye and pigment types, solvent inks, and ultraviolet
cure inks.
Limited ink options due to

thermal inkjet printers.
Durability Epson Micro Piezo print heads run much cooler than thermal
inkjet ones and can provide reliable operation for the life span
of the printer. Therefore, no Epson ink cartridge needs a print
head attached, making them more affordable, and
environmentally friendly.

Epson Micro Piezo print heads use less power than thermal
inkjet pint heads because the piezoelectric method of ink

Epson’s Variable Sized Droplet Technology (VSDT)
Variable Size Droplet Technology (VSDT) refers to the capability of Epson’s Micro Piezo print head technol
by varying the electrical charge given to the piezoelectric elements. This enables Epson’s printers to achie
1.5 picoliters. Epson Micro Piezo technology’s ability to achieve such superior precision results in shar
images - key qualities strongly associated through the years with Epson’s renowned photo-quality prints.
Epson’s Micro Piezo Advantage
The two most commonly used inkjet printing systems in the market are Epson’s
Micro Piezo technology and thermal inkjet printing.
In an Epson Micro Piezo system, ink is ejected by precisely controlled mechanical
pressure.
On the other hand, thermal inkjet technology works by rapidly heating resistors
built behind the print head’s nozzles to vaporize the ink, creating a bubble which
expands so quickly that the ink literally explodes out of the nozzle onto the paper.When the bubble cools and collapses, the resulting vacuum pulls more ink into the
print head from the cartridge.
