Key Features

• Channels and Nozzles: Boasting 8 channels and 180 nozzles per channel, this printhead ensures precision in every droplet.
• Drop Size: With a 3.5 picoliter drop size and Variable-Sized Droplet technology, it guarantees exceptional print quality.
• Latest DX7 Model: As Epson’s recent release (2nd coded) in the DX7 series, the F189000 promises cutting-edge performance.

Printhead Versions

We offer three versions: ‘Not Coded’, ‘1st Coded’, and ‘2nd Coded’. Ensure you select the correct version for compatibility, as they are not interchangeable. This encrypted version seamlessly integrates with new printhead control boards on recently manufactured printers.

Note: The head ID alone cannot determine the head type; it’s crucial to check if the old printhead is 2nd coded before any new head installation.

What is “Micro-Piezo” technology?

“Micro-Piezo” refers to a specific technology used in inkjet printing, and it is often associated with the brand Epson products. Let’s break down what “Micro-Piezo” means:

1. Micro-Droplet Formation:

   • Micro: Indicates that the droplets of ink ejected by the printhead are very small, typically in the micrometer range. This allows for precise and detailed printing, contributing to high-resolution output.

2. Piezo-Electric Elements:

   • Piezo: Stands for piezoelectric, a material property that changes shape when an electric field is applied. In the context of inkjet printing, this usually refers to piezoelectric crystals or elements.

3. How Micro-Piezo Works:

   • In a Micro-Piezo inkjet printhead, tiny piezoelectric elements are positioned behind each ink nozzle. When an electric current is applied to these elements, they deform or change shape. This deformation creates pressure within the ink chamber, forcing a small droplet of ink to be expelled through the nozzle onto the printing surface.

4. Benefits  of Micro-Piezo technology:

   • Precision: Micro-Piezo technology allows for precise control over the size and placement of ink droplets, resulting in sharp and detailed prints.
   • Versatility: It can handle a wide range of ink formulations, making it suitable for various printing applications, including text, graphics, and even high-quality photo prints.
   • Durability: The absence of heating elements, as seen in other inkjet technologies like thermal inkjet, can contribute to the durability of Micro-Piezo printheads.

5. Applications of Micro-Piezo:

   • Micro-Piezo technology is commonly used in a variety of printers, including those designed for home and office use, as well as industrial and large-format printers.
