Micro-Type Inkjet Printers

What is Inkjet Printers?

Inkjet printers are a type of printer that uses tiny droplets of ink to produce images and text on paper or other materials. Inkjet printers are commonly used in homes and offices for printing documents, photos, and other graphics.

Types of Inkjet Printers

Inkjet printers work by spraying microscopic droplets of ink onto paper or other materials through a printhead. The printhead contains a series of nozzles that release the ink droplets onto the page. The size and location of the droplets are carefully controlled to produce sharp and detailed images and text.

How does a Inkjet Printer Work?

There are two types of inkjet printers: thermal inkjet and piezoelectric inkjet. Thermal inkjet printers heat the ink to create tiny bubbles that force the ink onto the page, while piezoelectric inkjet printers use electrically charged crystals to push the ink onto the page.

Piezoelectric Inkjet

Piezoelectric printing technology uses piezoelectric material as the main active element inside the print head. The material produces a phenomenon known as the piezoelectric effect, in which a (natural) substance generates an electric charge when it is subjected to an external force. Another effect, the inverse piezoelectric effect, also occurs when an electric charge acts on the substance, causing the substance to deform (move).

Piezo printheads feature PZT, a piezoelectric material that has been electrically polarized. All piezo printheads work in this same way, deforming the material in order to eject ink droplets. A printhead is an integral part of a printing system with nozzles that eject ink.

Piezo printheads consist of an active component called an actuator, with a series of lines and channels forming a so-called “fluid pathway”, and some electronics to control the individual channels.

The driver consists of parallel walls made of PZT material, forming channels. An electric current is applied to the ink channels, causing the channel walls to move. The movement of the walls of the ink channels creates acoustic pressure waves that force the ink to exit the nozzles at the end of each channel.

NICEJET A400-40Si Inkjet Printer

The NICEJET A400-40Si inkjet printer uses unique ink viscosity and liquid level detection technology for high print quality with more anti-migration and yellow inks than similar machines. It has a fully disassemblable nozzle design to solve the nozzle clogging problem and reduce operating costs. Furthermore, it’s designed with a magnetic non-contact high voltage switch to avoid machine failures caused by poor contact after long-term use.
